I have used this shampoo for the past 2-years, and it has been a godsend. My hair had become very thin due to a medical problem. The shampoo has gradually improved both the condition and thickness of my hair, which is now a lot thicker with a healthy bounce & shine. I took my time to decide to try it, but have to say, its worth the extra simply because it actually works. I would not be with out my hero product. thanky ou kerastase

I've been used this shampoo for 4 months (daily washing) and it definitely worked for me. My hair is fine and I used to have a sink full of hair after brushing, but now it's never more than just a few hairs there and there, nothing out of ordinary. Even my boyfriend noticed that my hair is a lot shinier and thicker. I also feel that my hair is a lot healthier and stronger. The formula of the shampoo is thick and foams really well, and doesn't overweight the hair. Fabulous stuff!

Excellent daily wash shampoo especially when used in conjunction with their Aminexil GL six week programme which is designed to maintain hair density. It is also very good when used in conjunction with some of the other popular hair rebuilders and thickeners on the market as this shampoo balances the proteins to the scalp, vastly reducing protein overload which causes hairloss/shedding, thus the word "prevention" in the title. I have used for years now so I definitely recommend it!

I have used lots of different shampoos and none have ever really worked. When my stylist recommended this product I was reluctant to try it, but it really does work. My hair feels, healthy, thicker and looks shiny. I would never dream, of going back to any other shampoo! Miss253
