My hair was damaged badly from hair extensions, heat, and stress. K18 made my hair look and feel healthier! I just went for my six week hair appointment, and she asked what I was doing differently. I told her K18! She said to keep using it because my hair hasn't been this healthy in the last two years. I highly recommend K18 products! The cost may seem high, BUT a little goes a long way with K18! Well worth the cost!

Love this shampoo!
I love using this system. I have very course, wavy hair and it makes it so manageable.

Had to Have
I got a sample of this and the conditioner when I bought the mask. After using the samples and the mask over a week, I was amazed at the change in my hair's texture and manageability. I had to have the full size to use as my primary shampoo and conditioner.
