Strengthens, hardens, makes more resistant and gives volume to thin hair! Highly recommended for thin hair!

Kerastase products are a guarantee.. I have been using various types for many years and I am always completely satisfied. They are worth their money.

It oils the hair and makes it look greasy. On the positive side, it prevents frizz and adds density. It also has a nice scent. I would not buy it again.

All Kerastase products are a guarantee. They perfectly meet the properties they state. I trust them completely.

I was very satisfied! I have long hair with fine strands that tend to frizz when blow-dried, and I wanted to do an anti-frizz treatment. But with the closure of hair salons and using only this specific shampoo with its mask, my hair became shiny, soft, and easy to comb within two months.
I highly recommend it!

The worst thing is that I got pimples on my scalp and I had to go to the dermatologist to finally give me a medicated shampoo because it messed up the pH of my scalp!
