Leave-in Molecular Repair Hair Mask - Treatment for Damaged Hair

K18

Really does seem to work miracles, my bleached hair is noticeably softer, just doesn't seem as good quality for money buying the smaller sizes, especially as it's hard to identify when the container is empty due to the design.

K18 Leave-In-Molecular Repair Hair Mask REVIEW

I enjoy using this product. It is something that shouldn't be used all the time. I personally use it only 1-2 a week and the days that I don't use it. I do go in with a different leave-in-conditioner and hair oil. It really brings back life into your hair. Disclaimer-I've only been using it for a few weeks but it is a product that I will be incorporating into my haircare routine system.

Do not use

This product ruined my hair.. my hair was very long and wavy/curly… I used it as a treatment… my hair broke off. I went from tailbone to bra strap length hair… called the company… they could not tell me anythinb to help. horrible!

Changed my Hair!

I have very course and dry hair, this treatment changed that within the first few uses. It is quite expensive, but well worth it. You don’t need to use a lot, and that’s coming from someone with very thick hair!

Magical hair treatment!

I have blonde (highlighted) very dry hair (due to highlighting and medical issues). Between the pool and beach this summer nothing was softening my hair. I bought this 2 days ago, used it that night - followed directions and my hair is soft and shiny again! I couldn’t believe that I didn’t use conditioner and my hair looks this good. My hair is long and very thick and I used 3 pumps and followed the directions exactly. I know it’s expensive but a small amount goes a long way. This is amazing!

Great product

Love K18 has really helped my hair repair and grow, highly recommend

Personally didn’t work for me

I was really excited to use this product as people seem to swear by it. However after using it several times I don’t think my hair is any better

Shouldn’t be on the market

Don’t buy this product. Unless you have the right hair type for it (who knows this? I didn’t) it will slam so much protein into your hair that your strands will stretch and snap. I used it twice—followed the directions to a T—and the breakage is outrageous. breakage

Miracle in a Bottle

I just bought the mini and used it once today. My hair is already looking so much better. I’m so excited to keep using it. Will definitely have to purchase the full size. My hair is bleached. Been getting highlights, dyed, and balayages for years. This product is well worth the investment.

I think it works

I think it works, but how can you really know? Ive used 3 bottles and my hair seems to grow without breaking as much but that may not be down to this product. Its easy to use though, however its very expensive

It’s okay

I lost half of my hair to bleach damage and got this hoping it would help. I think I noticed a slight difference immediately after using it, but as soon as I washed my hair again, it went back to feeling damaged. This may work for prople with heat damage or who want to majntain the healthy of already healthy hair, but this did not help my very damaged hair.

Not for Protein Sensitive Hair!

Oof...I got this as my birthday reward and gave it away. This made my hair super I My friends and husband even noted that my hair looked dull. It took a couple washes & deep conditionings to get it out. If your hair is protein or keratin sensitive I'd avoid this.
