I found this product at my hairdresser (who advised me), and since I use it after every shampoo and I am delighted. At first I thought it was still just another product that my hairdresser wanted to sell me to make a profit ... and maybe this was the case but prevents that after use I realized that this product is a true marvel. I really saw a great difference in my hair. This product untangles hair (and I have long hair mid-back), it repairs in moisturizing and nourishing thanks to its base of keratin, it makes them more soft and silky without greasy. And more, it feels super good, while asking for more ...
