Strengthen and protect strands with the Kérastase Resistance Serum Extentioniste, a nourishing leave-in hair serum that helps to protect against breakage. The non-greasy formula uses a host of powerful ceramides to seal the hair cuticle whilst a blend of lipids creates a smooth surface, creating a fortifying effect from the inside out.

The highly concentrated serum forms a defensive barrier over the scalp to protect against damaging environmental aggressors, whilst also sweeping away impurities for a fresh appearance. Hair will be boosted, revitalised and given improved resistance.

Really Nice

Smells divine... a little goes a long way in this product. Frizz and breakage on hair is already noticeably better after a couple of weeks. Wish the bottle was bigger! Also found it helps if you have a dry/ish scalp. A bit pricey but that’s A reflection of the quality :)

not sticky

I bought this product. There are many other scalp serum I had tried before. It's hard to compare the effect. However, this one is particularly not sticky and can be easily applied after shampoo or any other time.

Seeking long hair

Bought the whole line and used it about 3 times so it’s early days yet. But the serum doesn’t leave your hair feeling greasy and it feels lovely to apply and smells nice. Hopefully in a few weeks we will see some growth fingers crossed!

Hair life saver

I was having a really stressful time and my hair looked frazzled and wispy so decided to try this hair serum . So pleased that I did as 3 weeks later my hair is strengthened and glossy and manageable once again so I will continue to use twice weekly. I have fine hair but plenty of it and it’s naturally curly but tends to go fluffy if I don’t blow dry but this product doesn’t weigh your hair down or leave any nasty residue !
