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.
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
The sample was really tiny (I think we can all agree) but the few times I was able to use this I think its great. Light weight, adds shine, smooths. Very nice! Will purchase!5
I received this in my Birchbox as a sample and was put off by the tiny vial, but was pleasantly surprised by the product after the first try. Although the packaging is quite inconvenient, I have been using this for more than a week and I'm only maybe a third of the way through the vial (for my chin-length hair). It is a very effective product, it makes my hair soft and manageable to style and my hair looks soft and shiny all day. I'm buying this with some Birchbox points to soften the blow of the cost, but I know it will last a long time and be worth the expense because of the cost per use.4
