I bought this after reading glowing reviews on another site. I had high hopes for the product, but on my dry, color-treated, wavy hair, this was the worst straightener I have ever used. It made my hair very coarse, even drier than usual, and it was impossible to straigten because I could barely get my brush to pull through the product. I thought that maybe I had put too much balm in my hair, so I tried it again. I put a pea-sized amount in my medium length hair and had the same results. In my experience, this stuff was horrible! Save your money, buy Phytodefrisant instead!
