Was already using mask, was skeptical this would help even more. Was wrong. Spectacular results!

Hi. My hair has gotten fragile due to Hashimoto's Thyroiditis (the most common autoimmune condition among women). I had been using the Olaplex system (not made by this company), which is good and helped.

I tried the K18 mask and was blown away by the lack of frizz and overall healthy look and feel of my hair and it STOPPED HAIR FROM FALLING OUT!

I saw K18 had added shampoos to their line. I thought: "I'm already in good shape from the mask. Would adding a K18 shampoo really help more?"

The answer to that question, for me, is yes and it's not a subtle difference.

I tried it for the first time yesterday and was blown away (no pun intended!) by how healthy and shiny my hair looks!

That's why I am taking the time to write this review.

For most women, our hair health means a lot to us.

If this helps someone else with Hashimoto's that would make me very happy.

But even if your hair is not fragile due to a medical issue, if you color it (me), blow dry it (also me) and flat iron it (me again!), and you have the resources to spend on what are admittedly not inexpensive products, I think you will be very impressed at how healthy and shiny using the shampoo and mask together make your hair! (If you can only afford one, get the mask.)

LOVE THE PRODUCT! LOVE THE WAY IT MAKES MY HAIR FEEL. LOSING LESS HAIR SINCE USING.

I've only used it a couple of times so far, but my hair feels super clean afterward. It seems like the tangles come out easier after I put the leave in mask on.

Turning Straw back into Hair

I used a scalp scrub on my hair and then ends of my hair felt like straw. A wide tooth comb wouldn't even make it's way through the tangled mess. The next day I saw an add for K18 and have been impressed with the effectiveness of the products since they first touched my hair. The "wait 4 minutes" thing is a little odd, but end results makes the waiting SOO worth it. I cannot believe the shampoo and mask work exactly as advertised without any of the toxic chemicals found in most hair products that don't even work. This is the first product I have bought like this that actually worked 100% as described. No exaggeration necessary!

Thank you for your review Julie. Waiting the 4 minutes is what it takes for the K18 mask to reconnect broken polypeptide chains so it stays in to maintain the link contributing to hair’s renewed core strength and elasticity.
