I cannot believe how amazing this product is. I am 56 years old and have been dying my hair since I was 16 and at this age I had just accepted the fact that my hair will forever be dull, brittle and lifeless. And then I came across this product and it has forever changed my life. My hair is back to where it was before I started dying it. It is soft like silk, healthy, and so shiny. And if possible it seems like it is still getting better and better with every use. I will definitely be a customer for life. Thank you so much for creating a product that is going to change everyone’s life who uses it. I make sure I tell everyone about this product. Every time I look in the mirror I still can’t believe how amazing my hair looks now.

I do regular, tight 3b spiral perms to my naturally thick bone-straight hair every 4-6 months for about 10 years now—I’ve also bleached the bottom twice plus dyed it grey for an ombré effect. For what I put it through, it should look fried and crunchy (it has before), but Olaplex helped do a lot of damage control.
K18, however, is a different beast. This stuff actually makes my hair feel healed, it’s nuts—my ends that feel usually a little brittle feel super soft and “moisture-filled” from the inside, closer to virgin hair texture, I keep touching my hair. Olaplex and protein treatments definitely do help my hair, but K18 is a different feeling, it does feel Iike it’s restoring my hair closer to virgin hair, makes it break less, and gives it a healthy-looking luster.
One important caveat is that it *did* make my curl perm straighter after the 2nd use and I notice my ends aren’t as tightly curled. K18 team, definitely let your customers know just as an FYI ! Great stuff overall though
Teresa C.
A miracle in a bottle - especially during COVID lockdowns!
Alexandra R.
Truly cannot live without k18! I used to be bleach blonde and began to transition back to my natural color due to breakage. K18 absolutely saved my hair during that process. I still use it every week!
Peggy R.
This product is fantastic , it makes my hair feel silky and it now shines like never before. I highly recommend it !
Peggy R .
Jen G.
I lift my base color and add balayage, heat style often; as a result, I thought that I had to live with the ensuing damage. K18 is transformative! I saw a noticeable difference after the first use. Application couldn't be easier, and there was no weighed down feel after use. 3 months of dedicated Olaplex use couldn't compare with the results from my first use of K18. I am amazed, total HG hair product. Even my blonde is shiny!
I also received excellent customer service when the dispensing pump on my bottle wasn't working. You guys already have an incredible product, but the care and attention to customers is the icing on top. I'm a customer for life and will be sharing my find with all thr beauty lovers in my life!
Lisa C.
This is without a doubt the product I have ever used! I get my hair colored every three weeks and this has restored my hair to what it looked like when I was a teenager (40 years ago)
You will not be disappointed in fact you’ll be sorry you didn’t know about it sooner!
Rachel B.
My hair had bad breakage from using Olaplex and not offsetting with hydrating products. This is a MIRACLE product. My hair has never ever felt so soft. I honestly can’t stop touching. Thought it was just going to be another gimmick but holy cow this legitimately works. Price is pretty steep so won’t keep using it after my trial is done but highly recommend to get you back on track!
Rebekah
I have to say.... I rarely leave reviews so this alone speaks to me, but this is an amazing product. I’ve kicked dying my hair to the curb this year, to give it a break during this pandemic, but my hair is very damaged from the middle and down from bleaching it over and over. It detangles my hair like nothing I’ve ever used in my life, and I can see and feel a difference in the texture of my hair. I put a four on the review because I haven’t finished the recommended uses to kick off the treatment, since I don’t know how it will be long-term. You guys should seriously create a detangling maintenance spray or something, because... have mercy, this makes my hair feel like I’m combing through butter
Amanda M.
Been using olaplex for years and this stuff does “something special”. Instantly smooths hair and makes it shine.
God o.
I have used so many different products, this is the first time I feel a product is actually healing my hair.
Renee S.
I had a terrible bleach experience, I went from brown to blonde and was overprocessed with lots of breakage. 2 rounds of K18 treatments (at home), one trim, and one retone later I was transformed! I truly believe this mask saved my hair. A few years ago, I went to Hawaii and my hair got really dry after hotel shampoo + pool water + ocean water + daily washes, and it took half a year for my hair to recover. Wish I had K18 back then!!
Meg B.
It worked just “okay”. But my main objection is the price. Too damn much for a little better than mediocre product.
Victoria L.
I was lucky to buy early from Good Morning America Deals. I love it so much. It has changed my hair. Soft and manageable. It is totally Awesome!
Cris
This mask transformed my hair!
Princess L.
It made my hair super soft and easy to detangle
Fiorella G.
The leave-in mask has been a lifesaver for my hair! I’ve gone through multiple rounds of bleaching in order to get a silver/light brown hair color and the mask has made my hair noticeably softer. I can’t wait to stock up again. Definitely worth it.
Kristen W.
This is what I was dealing with. After doing tons of research, I found this glorious masque. I've used it 8 times now and I can completely tell a difference in texture, fly aways, and general condition. Prior to application, I use a clarifying shampoo and then apply the masque. Within in 4 minutes I experience a full transformation and can detangle with ease. If your hair needs repair, buy this product. Really. It works.
Jenna
Didn’t help me with any of my hair damage, the 4 minute rest made no sense when I had the style it in my hair which always weighed my fine hair down and made it look greasy and was just too expensive for doing nothing to my hair
Marlene W.
Used about 6 times so far but hair gets really frizzy by the afternoon. Would like to try the serum but looks like it is not available to the public. I asked my colorist to order but she will not. If I were to get the serum from you I could apply it myself before the coloring. Thank you! Desperate to get my course hair to look like the models in your photos!
Maria O.
I bought the biggest one for treatment but i didn't see anything in
Special, expensive not as effective as they say,
Christine G.
I will never be without this stuff again. It's hard to tell when you're first using it, but once you go back to shampooing/conditioning regularly, what a difference! My hair is so shiny and silky. People keep commenting on it. I share this product with every one of them. Thank you for making my hair amazing again!
Elizabeth N.
I wish it came in a much bigger bottle! I have long, thick hair and go through a bottle very quickly!
Sally D.
This conditioner takes care of any frizzies! It works as advertised. I love what it does for my long fine hair.
Azi F.
Amazing product so glad I found it!!! I keep recommending it to freind after friend
Donna K.
Just didn't work for me.
Louise W.
Great product- can't wait to buy more!!!
Stacey J.
This is a good product but people with fine hair need to know that you can get TOO much keratin and it will cause your hair to be brittle, break and feel like straw. I've done this and didn't realize that you can over use this product (or any keratin product). It would be helpful if you put this into your product info.
Stella J.
I had a horrible hair experience that caused some serious damage to my hair. I tired this product and it worked good. I noticed a difference. But as damaged as my hair was I don’t think it did enough on its own. So I paired it with olaplex shampoo and conditioner and was alternating with olaplex no3. That made a huge improvement and fast. My stylist was quite impressed with the improvement (my hair was really bad).
Carmen C.
Amazing transformation product!
Alexa L.
The product made my hair stick together. My hair is bleached and very dry and brittle. I didn't see any difference in my hair after using the product as directed for 2 weeks.
Irene B.
Excellent product. No more frizz.
Monica W.
less breaking and hair is silky. I will definitely keep using this product.
Atlantis L.
I have fine, dry hair that has been damaged by decades of highlights, chlorine and sun damage. Most “repair” treatments just weigh it down or make it look greasy. Your product took those decades away and returned my hair to its original texture. It’s baby soft and light and strong. This stuff is amazing.
Renee C.
My hair gets better every time I use it. This stuff is my hairs holy grail. So smooth and frizz free. I use twice a week. Keeps my hair on point. Will definitely be ordering my third bottle soon. Thank you!
Linda H.
Just try it. This product really is better than Olaplex. My ends are much healthier with less breakage and more shine. A little bit goes a long way in just 4 minutes.
Nancy D.
I love this product! I would love to buy the serum online. I don’t go to a salon that sells this product..
Angela F.
didn't see a difference at all, used it 6 times as directed and didn't notice any change in my hair
Candice W.
Unfortunately, this did absolutely nothing for my hair. It makes it look somewhat better upon initial application, but no more than any other substantially more affordable serum/conditioner etc.
Sarah B.
I thought my curls were ruined. There were inch-long straight pieces at the end of every stringy curl. K18 is restoring my curls.
I’ve used it for about three washes and I’m ordering more.
Sarah S.
I bought this for my own bleached hair and it worked wonderfully.
I tried it my mom’s mature ubleached was hair and it made it look thicker and soft with a beautiful texture and shine after 1 use
Nothing can truly repair damaged hair, but this stuff makes it look perfect.
I can’t wait to see how good it looks after regular use.
Jenny T.
I cannot say enough about this company. In an earlier review, I rated it 3 stars because the tubes weren't sealed properly. The company reached out and generously replaced all my tubes and more. The product is definitely making a significant different on my hair and now I can say it's the second best thing about the company. Customer service is HUGE for me and this company made me a very satisfied customer -- for life!
Suze M.
great product!! keep my hair softy and easier to style
Elaine B.
My hair is shiny , healthy and strong!
i can visibly see the difference!!
Galina G.
It’s the product is ok in my opinion. A little too pricey for the amount you get. I didn’t see that much difference to results of using a good a good deep conditioner.
Sandi L.
I thought my over-dyed hair dreams were over until I tried this stuff. It SAVED my hair! I would recommend this to anyone with exhausted hay-hair that just wants to feel pretty again. Let the giant squirrels get close because today is a new hair day!
Genie L.
It's worked wonders on my dry hair. Would be great if you can develop a shampoo that complements it!
Dawson K.
My hair was recently really really lightened. This product has definitely kept it from being fried.
Gretchen A.
I’m obsessed with this product. This product creates texture and volume while repairing your hair and making it healthy. I have fine coloured hair and not a lot of it and this makes my hair have so much vol7me. I’m so grateful to my colourist for introducing me to this product.
Lisa B.
I love this product! My hair is very dry and coarse, the hair mask makes a huge difference! The mask is very expensive so I don’t use it as much as I’d like.
Molly B.
It really seems to help my stressed, fine, color treated hair
Mia T.
My hair has been so damaged by bleaching it, I didn't know what to do. My hair literally rebound after using this product the 3 recommended times. Nothing else works.
Lauren T.
Thought the product was great! My hair seemed damaged from having to color every 3-4 weeks. Now it feels much healthier and looks fuller and seems to have more body.
Sally D.
Best smoothing and shining product I’ve ever used! I have dry coarse hair with no shine-this has changed my hair!
Barbara M.
I got scammed! This was perhaps one of the worst products I have ever used. I only use very good products for my hair including all Olaplex 3,4,5,6, New wash ,Oribe .
This product actually made my hair dry and course ! Don’t get ripped off like I did . The price is insane for the amount you get that you literally can’t even see how much is in bottle.
Carolyn C.
I use as instructed although my hair feels like it needs it after 2 days
Lindsey E.
This stuff is amazing. Eliminates frizz and has made my hair silky soft.
Billie J.
My hair is curly but when it dries it is frizzy. I have spent a small fortune trying to find a product so I could wash and let dry without styling. This product is amazing! I usually dry with big barrel dryer but I don’t have to. I would recommend this product to every one. I would like to try the serum but I can’t find where to order it.
Ce T.
Absolutely love this product. I do wish there were a window or indicator on the larger size to let us know when to buy more.......just sayin, come on we don't want to run out and it's pricey so timing os everything.
Tisa zito Z.
great product just waaaaaay to expensive. I dont know many people who can afford this even with a $10 off coupon. I would bring the price down if you want customers to stick around. It does work though.
Christine C.
I thought the tubes would be bigger or last a little longer for the cost
Nicola W.
This has actually been a game-changer. I am 46 years old, I highlight and keratin my hair. This thickened my hair and made it look lustrous again, like I was 30! I have used Plex products before and this was totally different. I would recommend this to anyone.
Karen R.
Did not experience the results I expected.
Penny M.
I am a hair dresser.. found it way to expensive, for my self and to use on customers. I did see some difference.. but I think the price is way too high. Thank u
Audrey F.
Due to age and damage, my hair was breaking off near the root. This product has definitely helped.
Carolyn B.
Awesome product.
Andrea S.
The product is amazing. It definitely changes your hair for the better. Well worth the money. You are worth it.
Laura M.
Love this product, my hair can handle anything. I spend a lot of time in the ocean, which leaves my hair dry and corse. Not anymore❤️
Sunday W.
I’m so happy with my results. My hair is so strong, soft & manageable. I’m a customer for life!
Graciela F.
I wanted to like it. It's a small container. I think its too expensive. I used it twice but just seems I could get more for the amount paid. I did not see anything spectacular about this. I can put mayonnaise and get bouncy hair! I think I would have to buy more to determine if really that good but no, it's not happening during this pandemic. Money is tight and I spent money. I was not ecstatic or thrilled. I may give another competitor a chance when the time is right. thank you for allow me to "try" with promo code but I cant afford to keep using this to see long term outcome. Good Luck everyone
Ingrid H.
Made my hair very dry and frizzy
Beverly S.
I love the way my rather frizzy, wavy hair feels and looks when I use this product. One of the best things is cutting out the conditioner step when I wash my hair. I'm sold!!!!!
Claudia B.
I thought it would be a better product to rap air my hair
Felice R.
This worked for my hair well better than Olaplex
Lisa D.
I'm not noticing any difference.
ANNIE H.
Hair feels great after shower, gets all the dryness and tangles out of processed hair. Would be great if I could see how Much product is left to know when to reorder.
Annie
Kay P.
Love how it makes your hair feel new soft and alive. Not happy with size and how many uses you get for such a high price used 3 pack to try it out then bought the pump I loved it so much but it only last 5 shampoos
Gaye H.
My hair was in terrible condition.i read about your product and following the directions precisely,especially less is more’,and could instantly see an improvement! I would recommend this product to anyone,with hair in any condition!
sheila c.
this product works great, a little bit goes a long way and really makes my hair soft, shiny and healthy
Sharon B.
This stuff is a game changer. I have used it 4 times now and cancelled my hair appointment. The curl is so defined and my texture is so soft. I have very thick hair so that means a lot to me... Can run my fingers through it without getting caught up.
Rebecca S.
In only a few applications, It has brought my hair that had been affected by sun, color, tint and styling back to the soft, youthful, smooth feeling and looking hair I’ve been longing for!! I’m excited to see how wonderful the hair will be with additional use. This is by far, the BEST product I’ve had the good fortune to try!
Tina Jovanna D.
I am amazed. This stuff is the real deal, way better than olaplex and I use the entire line.
Bethany T.
I think it does wonders for the hair however it doesn’t last very long, using 2-3 pumps every 3 washes I am already out. So extremely pricey for only a few weeks worth of use.
Jeannette D.
Back in January 2020 a hairdresser bleached my hair so bad is was breaking off, dry and just horrible. I was devastated tried so many products and stumbled on this.
After my second use I honestly could not believe the texture it was soft and smooth felt like my hair again. THANK YOU!!! I am now a Loyal customer.
Nan R.
So far I’ve used three tubes. I think it’s really amazing, so much so that I ordered the larger container. I took one star off due to the fact if I Really wanted to get this all over my hair, I would have had to have used All 3 tubes in one setting if not more, and, I just received the larger container, held it up to the light and it’s only 2/3 full!! I’m sure it’s done by weight but the size makes you think you’re actually going to get enough to do your thick hair correctly. Very disappointed. Wayyyy to expensive unless you have super thin hair. But it Does work :)
Renee C.
This stuff is absolutely amazing. I have never had a product that I’ve ever been this happy with. My hair was so dry and brittle. After one use my hair had an amazing shine and softness I haven’t felt in years. Absolutely no crispy edges and ends. Incredible. I get to keep my platinum color for good. Finally, at 50 I have hair off a 20 year old!
Roux L.
My hair feels like one dry lock of hair
ann d.
Contains Propylene Glycol!! Second ingredient, which means it has more of that any helpful ingredients. PG has no redeeming qualities.
Ce T.
I saw results with the first use. Now, 5 treatments in, my hair is so much smoother, shinier and softer.
Sirel M.
I have over processed, chemically damaged, fryed hair. I just received my first order, let me tell you my hair feels amazing, looks healthy and manageable. Love It! I highly recommend this product. The only regret I have is that I only order the starter kit. I will be ordering the bigger bottle. Thank you, thank you and thank you!
Ana A.
I like the product I saw results on the second use. Of course on the second use I used the rest of the product because I have long hair. I just wish it was a bigger container for the length of my hair. Other than that is a good product!
JESUS H.
My hair felt like it had a film on it, made it feel almost sticky and looked super dull. All the reviews made it seem like the greatest thing ever, but fell short in my book.
Adalia B.
I used for first time at home and leave my hair looking healthy on the first time. No conditioner required just shampoo towel dry and really work for me. Last week I went to do my hair to the salón and I asked my hairdresser to use this product and she say it does what it promises boom good product, expensive but works.
Maria G.
A colleague of mine recommended this product to me. I was complaining that my hair was dry from washing it So often but that I was working out and couldn’t not wash it. My mom and I both tried this product and it had TRANSFORMED our hair. It’s not soft and healthy and feels stronger. Best hair product out there !
Karmen F.
My hair got FRAZZLED over quarantine as I continued to bleach and dye it (what else was I supposed to do with all my spare time?!). My hair was melting off in chunks when wet, especially around my face and ears. My hair crunched when dry, and had no movement at all. I saw a video on the website of a lovely lady with pink hair (like mine!) saying that she could keep her pink hair long with this product, and I said SIGN ME UP, it can't hurt! It was a good choice. For my hair, I use 4 pumps, one for each section, without using conditioner in-shower, and WHAM. My hair has that good, slippery hair feeling after I put it in, you know what feeling I mean. No stickiness, no crunchiness, no oiliness. Just slick, clean, moisturized hair. I'm addicted. My hair isn't back to the length I want YET, but this is going to help me get there! I already see the difference!
valerie s.
Not impressed at all. Total waste of money. I've used it four times and it has done nothing but make my hair frizzy. Very disappointed.
Marla K.
I have used it Twice and I love how it makes my hair feel -wonderful
Erica w.
I waited to use it 4 times to write this review. I followed the instructions but I honestly did not see any difference in my hair at all. It was very expensive. I feel it is a complete waste of money. I have course dry hair and I would not recommend this product.
Robin G.
Love how my hair feels!
Yvette N.
This was 50ml, yet I got a total of 4 pumps from this container. This is disappointing as I was just starting to see results after 2 applications. Did I get a defective container?

Angela F.
didn't see a difference at all, used it 6 times as directed and didn't notice any change in my hair
Candice W.
Unfortunately, this did absolutely nothing for my hair. It makes it look somewhat better upon initial application, but no more than any other substantially more affordable serum/conditioner etc.
Sarah B.
I thought my curls were ruined. There were inch-long straight pieces at the end of every stringy curl. K18 is restoring my curls.
I’ve used it for about three washes and I’m ordering more.
Sarah S.
I bought this for my own bleached hair and it worked wonderfully.
I tried it my mom’s mature ubleached was hair and it made it look thicker and soft with a beautiful texture and shine after 1 use
Nothing can truly repair damaged hair, but this stuff makes it look perfect.
I can’t wait to see how good it looks after regular use.
Jenny T.
I cannot say enough about this company. In an earlier review, I rated it 3 stars because the tubes weren't sealed properly. The company reached out and generously replaced all my tubes and more. The product is definitely making a significant different on my hair and now I can say it's the second best thing about the company. Customer service is HUGE for me and this company made me a very satisfied customer -- for life!
Suze M.
great product!! keep my hair softy and easier to style
Elaine B.
My hair is shiny , healthy and strong!
i can visibly see the difference!!
Galina G.
It’s the product is ok in my opinion. A little too pricey for the amount you get. I didn’t see that much difference to results of using a good a good deep conditioner.
Sandi L.
I thought my over-dyed hair dreams were over until I tried this stuff. It SAVED my hair! I would recommend this to anyone with exhausted hay-hair that just wants to feel pretty again. Let the giant squirrels get close because today is a new hair day!
Genie L.
It's worked wonders on my dry hair. Would be great if you can develop a shampoo that complements it!
Dawson K.
My hair was recently really really lightened. This product has definitely kept it from being fried.
Gretchen A.
I’m obsessed with this product. This product creates texture and volume while repairing your hair and making it healthy. I have fine coloured hair and not a lot of it and this makes my hair have so much vol7me. I’m so grateful to my colourist for introducing me to this product.
Lisa B.
I love this product! My hair is very dry and coarse, the hair mask makes a huge difference! The mask is very expensive so I don’t use it as much as I’d like.
Molly B.
It really seems to help my stressed, fine, color treated hair
Mia T.
My hair has been so damaged by bleaching it, I didn't know what to do. My hair literally rebound after using this product the 3 recommended times. Nothing else works.
Lauren T.
Thought the product was great! My hair seemed damaged from having to color every 3-4 weeks. Now it feels much healthier and looks fuller and seems to have more body.
Sally D.
Best smoothing and shining product I’ve ever used! I have dry coarse hair with no shine-this has changed my hair!
Barbara M.
I got scammed! This was perhaps one of the worst products I have ever used. I only use very good products for my hair including all Olaplex 3,4,5,6, New wash ,Oribe .
This product actually made my hair dry and course ! Don’t get ripped off like I did . The price is insane for the amount you get that you literally can’t even see how much is in bottle.
Carolyn C.
I use as instructed although my hair feels like it needs it after 2 days
Lindsey E.
This stuff is amazing. Eliminates frizz and has made my hair silky soft.
Billie J.
My hair is curly but when it dries it is frizzy. I have spent a small fortune trying to find a product so I could wash and let dry without styling. This product is amazing! I usually dry with big barrel dryer but I don’t have to. I would recommend this product to every one. I would like to try the serum but I can’t find where to order it.
Ce T.
Absolutely love this product. I do wish there were a window or indicator on the larger size to let us know when to buy more.......just sayin, come on we don't want to run out and it's pricey so timing os everything.
Tisa zito Z.
great product just waaaaaay to expensive. I dont know many people who can afford this even with a $10 off coupon. I would bring the price down if you want customers to stick around. It does work though.
Christine C.
I thought the tubes would be bigger or last a little longer for the cost
Nicola W.
This has actually been a game-changer. I am 46 years old, I highlight and keratin my hair. This thickened my hair and made it look lustrous again, like I was 30! I have used Plex products before and this was totally different. I would recommend this to anyone.
Karen R.
Did not experience the results I expected.
Penny M.
I am a hair dresser.. found it way to expensive, for my self and to use on customers. I did see some difference.. but I think the price is way too high. Thank u
Audrey F.
Due to age and damage, my hair was breaking off near the root. This product has definitely helped.
Carolyn B.
Awesome product.
Andrea S.
The product is amazing. It definitely changes your hair for the better. Well worth the money. You are worth it.
Laura M.
Love this product, my hair can handle anything. I spend a lot of time in the ocean, which leaves my hair dry and corse. Not anymore❤️
Sunday W.
I’m so happy with my results. My hair is so strong, soft & manageable. I’m a customer for life!
Graciela F.
I wanted to like it. It's a small container. I think its too expensive. I used it twice but just seems I could get more for the amount paid. I did not see anything spectacular about this. I can put mayonnaise and get bouncy hair! I think I would have to buy more to determine if really that good but no, it's not happening during this pandemic. Money is tight and I spent money. I was not ecstatic or thrilled. I may give another competitor a chance when the time is right. thank you for allow me to "try" with promo code but I cant afford to keep using this to see long term outcome. Good Luck everyone
Ingrid H.
Made my hair very dry and frizzy
Beverly S.
I love the way my rather frizzy, wavy hair feels and looks when I use this product. One of the best things is cutting out the conditioner step when I wash my hair. I'm sold!!!!!
Claudia B.
I thought it would be a better product to rap air my hair
Felice R.
This worked for my hair well better than Olaplex
Lisa D.
I'm not noticing any difference.
ANNIE H.
Hair feels great after shower, gets all the dryness and tangles out of processed hair. Would be great if I could see how Much product is left to know when to reorder.
Annie
Kay P.
Love how it makes your hair feel new soft and alive. Not happy with size and how many uses you get for such a high price used 3 pack to try it out then bought the pump I loved it so much but it only last 5 shampoos
Gaye H.
My hair was in terrible condition.i read about your product and following the directions precisely,especially less is more’,and could instantly see an improvement! I would recommend this product to anyone,with hair in any condition!
sheila c.
this product works great, a little bit goes a long way and really makes my hair soft, shiny and healthy
Sharon B.
This stuff is a game changer. I have used it 4 times now and cancelled my hair appointment. The curl is so defined and my texture is so soft. I have very thick hair so that means a lot to me... Can run my fingers through it without getting caught up.
Rebecca S.
In only a few applications, It has brought my hair that had been affected by sun, color, tint and styling back to the soft, youthful, smooth feeling and looking hair I’ve been longing for!! I’m excited to see how wonderful the hair will be with additional use. This is by far, the BEST product I’ve had the good fortune to try!
Tina Jovanna D.
I am amazed. This stuff is the real deal, way better than olaplex and I use the entire line.
Bethany T.
I think it does wonders for the hair however it doesn’t last very long, using 2-3 pumps every 3 washes I am already out. So extremely pricey for only a few weeks worth of use.
Jeannette D.
Back in January 2020 a hairdresser bleached my hair so bad is was breaking off, dry and just horrible. I was devastated tried so many products and stumbled on this.
After my second use I honestly could not believe the texture it was soft and smooth felt like my hair again. THANK YOU!!! I am now a Loyal customer.
Nan R.
So far I’ve used three tubes. I think it’s really amazing, so much so that I ordered the larger container. I took one star off due to the fact if I Really wanted to get this all over my hair, I would have had to have used All 3 tubes in one setting if not more, and, I just received the larger container, held it up to the light and it’s only 2/3 full!! I’m sure it’s done by weight but the size makes you think you’re actually going to get enough to do your thick hair correctly. Very disappointed. Wayyyy to expensive unless you have super thin hair. But it Does work :)
Renee C.
This stuff is absolutely amazing. I have never had a product that I’ve ever been this happy with. My hair was so dry and brittle. After one use my hair had an amazing shine and softness I haven’t felt in years. Absolutely no crispy edges and ends. Incredible. I get to keep my platinum color for good. Finally, at 50 I have hair off a 20 year old!
Roux L.
My hair feels like one dry lock of hair
ann d.
Contains Propylene Glycol!! Second ingredient, which means it has more of that any helpful ingredients. PG has no redeeming qualities.
Ce T.
I saw results with the first use. Now, 5 treatments in, my hair is so much smoother, shinier and softer.
Sirel M.
I have over processed, chemically damaged, fryed hair. I just received my first order, let me tell you my hair feels amazing, looks healthy and manageable. Love It! I highly recommend this product. The only regret I have is that I only order the starter kit. I will be ordering the bigger bottle. Thank you, thank you and thank you!
Ana A.
I like the product I saw results on the second use. Of course on the second use I used the rest of the product because I have long hair. I just wish it was a bigger container for the length of my hair. Other than that is a good product!
JESUS H.
My hair felt like it had a film on it, made it feel almost sticky and looked super dull. All the reviews made it seem like the greatest thing ever, but fell short in my book.
Adalia B.
I used for first time at home and leave my hair looking healthy on the first time. No conditioner required just shampoo towel dry and really work for me. Last week I went to do my hair to the salón and I asked my hairdresser to use this product and she say it does what it promises boom good product, expensive but works.
Maria G.
A colleague of mine recommended this product to me. I was complaining that my hair was dry from washing it So often but that I was working out and couldn’t not wash it. My mom and I both tried this product and it had TRANSFORMED our hair. It’s not soft and healthy and feels stronger. Best hair product out there !
Karmen F.
My hair got FRAZZLED over quarantine as I continued to bleach and dye it (what else was I supposed to do with all my spare time?!). My hair was melting off in chunks when wet, especially around my face and ears. My hair crunched when dry, and had no movement at all. I saw a video on the website of a lovely lady with pink hair (like mine!) saying that she could keep her pink hair long with this product, and I said SIGN ME UP, it can't hurt! It was a good choice. For my hair, I use 4 pumps, one for each section, without using conditioner in-shower, and WHAM. My hair has that good, slippery hair feeling after I put it in, you know what feeling I mean. No stickiness, no crunchiness, no oiliness. Just slick, clean, moisturized hair. I'm addicted. My hair isn't back to the length I want YET, but this is going to help me get there! I already see the difference!
valerie s.
Not impressed at all. Total waste of money. I've used it four times and it has done nothing but make my hair frizzy. Very disappointed.
Marla K.
I have used it Twice and I love how it makes my hair feel -wonderful
Erica w.
I waited to use it 4 times to write this review. I followed the instructions but I honestly did not see any difference in my hair at all. It was very expensive. I feel it is a complete waste of money. I have course dry hair and I would not recommend this product.
Robin G.
Love how my hair feels!
Yvette N.
This was 50ml, yet I got a total of 4 pumps from this container. This is disappointing as I was just starting to see results after 2 applications. Did I get a defective container?
