I bounce between Oribe, Davines and Pai Shau and pai shau is by far my favorite. I recently added more highlights and my hair was breaking about 3inches from the root. I’ve used the mask once and the replenishing line plus biphasic infusion for 1 week and my hair is almost back to normal! I was planning on cutting it super short due to the damage but now I only need about an inch off. I have fine have level 4 with highlights and it’s long. I live in a humid tropical environment. The mask, replenishing line and biphasic infusion is not too heavy for my hair. When I don’t highlight my hair I do use the volume shampoo. If they would make a dry shampoo my life would be complete.
