I have INCREDIBLY damaged hair. The ends of my hair have been bleached well over six times, had color remover 3 times, and been dyed with black box dye over three time and other dyes even more. None of this was done professionally or with high quality products, and so my hair is quite literally fried. Naturally I have very wavy hair along with loose curls, with all the damage, my hair texture has changed drastically. This product brought it back. After finishing the five treatments, I decided to just shampoo and condition, no products, no special methods, no scrunching, and just let it air dry. To my total surprise, my hair dried with almost no frizz, waves, and even ringlet curls. I haven't had my hair be this texture in YEARS. I can pull on my hair now and not have chunks break off. My hair's natural texture has been rejuvenated. It drastically increased the strength of my hair.
