Ever since we watched the first season of “Gossip Girl,” we’ve been huge fans of Blake Lively’s flowing waves. So we were excited to learn that the blonde actress was the inspiration behind Kérastase’s new serum. Specially designed for long hair, the leave-in treatment adds a high-definition shine while sealing each cuticle (bye bye, split ends). Plus, the light, gorgeously scented formula won’t weigh down your strands.
I am a daily serum user on my dry, blonde ends and this serum worked wonders! It smells really great and it did not leave my hair feeling greasy. I'm a fan!5
This product left my fine/oily/dry long hair shiny and soft. I love Kerastase! Don't love the price! Wish the sample was bigger, but I am definitely going to purchase. Love, love, love!!!!5
This product works really well. It reduces frizz, makes my hair shine and makes it really soft. The price is a bit of a deterrent, I have used similar products that work just as well and are less expensive.4
This works really well i'm excited to purchase it.5
I have a love/hate relationship with these hair serum samples- I use serum and always appreciate getting something that works and is wanted, but I have enough at home where I don't need to buy anymore anytime soon! This sample itself was good for use before a blowout- I do feel that it tamed my frizz and added my shine. I applied it only to my ends.3
Great product, but hard to tell if I wanted to purchase because the sample only had a couple of uses. Wish that it was bigger.4
This product delivers and more, leaves hair looking polished with some shine but not too much. Even more amazing when used in conjunction with the shampoo and conditioner from the same line.5
I have very long ( about an inch above my belly button), thick, curly hair that gets greasy QUICK. I have to be very careful of what I put on my hair. Well this stuff is amazing!! It sealed my frayed ends and added tons of shine. I didn't notice a huge different in frizz control but I still would recommend this!! I will be buying ASAP5
Great shine added to my hair without feeling overly heavy, which happens all too often with hair serums.4
The product is okay with my hair but not the best, it depends on your hair ultimately3
