This product is MAGIC. I let myself tempted after all the glowing reviews that can be read on Amazon. I admit that I was a septic ... This product therefore applies to wet hair. My hair was in a disastrous state, dry forked tips, dull. In short, a disaster (which I was responsible following an almost daily use of hair dryer / liseur)! It has only two uses of this treatment they regain shine and strength! On first use, I let rest the product overnight. And the second time just 5 minutes before drying, and I must admit that each time the result was immediate. Friends have even thought that I was going to the hairdresser so the change was dramatic! While it is true that the product feels strong ... But it feels good! A real good capillary discovery!
