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.
A lot of times hair products can weight my hair down or make it feel greasy but this was the opposite. It's fantastic! I like it so much that I threw the sample in my purse to always have with me5
I love this product. I would buy, but I have so many hair products to last a lifetime I think. This product is really wonderful. I love products for your hair that smell great and makes the hair shiny and healthy looking.5
This product smells so good I thought I had accidentally put perfume on my hair. I only put it on my ends and they seemed shiny and smooth after blow drying.4
I tend to go as natural as possible with my hair, but sometimes the frizz and fly aways require some taming. This product did the trick! I wish I had more, but they sell it at my salon, so I purchased it before my sample was even gone!5
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
