Kérastase Nutritive Nourishing Hair Serum with Niacinamide, Overnight Leave-In Treatment for Dry Hair, Lightweight and Non-Greasy, 8H Magic Night Serum

Love this product , makes my hair look amazing and smells good as well

Smells amazing and my hair is so soft in the morning, love it (but pricey stuff)

Good product - does not leave hair looking or feeling greasy

Easy to use website, bought as a present for my grandaughter.

It leaves a wonderful smell, I haven't seen much difference in terms of quality yet, but my hair becomes silkier when I apply it, that's all that happened to my hair

Fantastic hair product

The best hair night serum I’ve used. Just some drops after bed and your hair in the next day is really moisturised. This amazing serum just bring the health to your hair again.

A complete waste of money. I couldn’t see any difference and it leaves residue on the hair which makes it look dull and heavy
