K18 has completely changed my hair!!
I have been using the K18 damage repair shampoo and conditioner for about three years and my hair ALWAYS looks and feels amazing. It is finally growing out in a healthy way, always looks shiny, feels like silk. I added the Heat Bounce to my routine about 6 months ago and am completely hooked! This entire line is AMAZING!!!

Great heat protectant
I use this now after every wash to protect before styling. Works wonders and I can tell it is protecting my hair because my hair strength is improving.
