My hair started breaking after it was highlighted :( my friend who is a hairdresser recommended k18 hair mask. It has literally saved my hair. My hair feels fuller with more body, but most importantly it finally feels healthy again and i don’t see anymore breakage. I wish it was a little cheaper, but it’s worth the price IMO.

I am a professional stylist of hair/Salon owner, and have been in the industry fire close to 49 years. I am a salon owner in Columbia South Carolina, I went into Salon Cenrtric for one line of product that works similar to K18, and was redirected to, K18 by the store clerk. He explained to me that K18 was “the new kid on the block”, and a game changer. I got excited, and purchase the small sample kit for right under $60. Used the product as instructed on tithe majority of my clients that entire week, because I felt that if they had not had a K18 treatment they needed to get their hair had not been properly conditioned up until this point. Although I use professional products and emphasize on healthy hair, after I saw the results of what K18 does to the hair, I was sold, and went back to Salon Centric and purchased all back bar sizes of the line, and didn’t mind investing the approximately $550 in this product. I knew it would be worth it, and I knew it wouldn’t take long to get the return on my investment. As little as 1 month maybe sooner! This especially after we consult with our clients and explain what the K18 if for and what it will do to their hair. At this point I don’t see the purpose for using any of the shampoos and conditioners that I already have and been using on my clients. K18 is the answer to all of my clients hair care needs. A GAME CHANGER. I no longer have to guess and invest in other products not knowing and seeing it’s just a waste of time and money, because they can’t do what K18 does. Using K18 is like having a trusting business partner!!💕

I shampoo my hair and put in one squirt before blow drying. I do not have to use any product in my hair and it comes out so smooth. I love it!

I have finally grown my hair to hip length, but years of dyeing made the lower lengths & ends feel SUPER dry & damaged. After trimming ~1in. to get rid of split ends, I used K18 (after 6 consecutive washes, then once a week) & have gotten to a point where I feel confident I won't have to cut off more hair for it to keep feeling soft & healthy. This is one product I've had several empties of bc it really does work for me, especially since I want to continue dyeing my hair as it grows. If they had ever made the 5oz available for the public, I would be buying that without hesitation.
