Game Changer Stuff!
I live overseas and haven’t found a stylist I LOVE yet, so I have had to be extra mindful with my at home care, especially since I regularly color my hair. The Brazil sun and chemicals totally dry my hair out and when I use the detox shampoo (and leave in mask) my hair is totally transformed. I went home last month and my stylist said she could feel the difference in my hair. Yes this product line is pricey but I do believe it’s worth it and it cuts my wash day routine in half. My hair feels so clean and healthy after using this shampoo and ready to be styled with no issues. Before & after pictures of dryness then shine.

Incredible results!!
After one Peptide Prep shampoo my hair felt clean and I was able to comb through without conditioning. I followed with K18 leave in conditioner before blow drying and styling. My hair stayed smooth and shiny, and feels soft again, like when I was a child! I have gotten many compliments on my color since using k18.

Love this product!
I feel like this truly gets all of the build up of process and such off of my hair. It also does that without excessively drying it. If you saw my ends before, you would be shocked at the difference.

Please Don't Ever Stop Making This!
I have PCOS which gives me a VERY oily skin type. My scalp produces a lot of oil and sebum that becomes itchy after 2-3 days. I thought for the longest time it was a dandruff issue but neither drugstore nor prescription dandruff shampoos helped. I also tired many different clarifying shampoos that did not clean my scalp very well and made my hair ratty and dry. I came across an online forum saying K18 Peptide Prep was great for oily scalps ... so I decided to give it a shot in spite of the hefty price tag. It is worth every penny though! I am now on my second bottle and will keep buying it as long as K18 keeps making it. It cleans my scalp so well that I can now go 5 or 6 days between washes while leaving my hair soft and manageable. Best of all, my scalp does not itch like crazy anymore. THANK YOU K18 FOR MAKING A WONDERFUL SHAMPOO!
