I use is Kerastase shampoo before and have found this not to be the best one. It's a really thin liquid consistency which means I'm having to wash and rinse 2-3 times in one go as it doesn't spread very well.I have thin hair just past my shoulders. I find that my hair is really shiny after and smells good but don't get value for money as I'm using at least twice as much with each wash. I prefer a creamy consistency like the bain force architecte.
