Kérastase is always great. I love this serum in particular, it really hydrated my dry hair. 

I never twigged that the state of my hair was directly related to scalp health. I had itchy, dry and irritated scalp and my hair was utterly parched and peri menopausal. I use this serum every wash and the difference was noticeable after the first wash. My hair is shiny, stronger and no longer damaged.

I’ve only used it a couple of times and I’m already in love with it. It leaves my hair so soft and scalp feels cleaner. 

I wanted to take my scalp health seriously and I find that this product helps. Was worried it would make my hair oily but haven’t found that to be the case 

I wasn’t sure how this would go I was scared it would make my hair oily but instead just makes my scalp fresh
