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 used just a small amount at the ends of my hair since I have such fine hair and it made my hair look greasy.1
Wow, this product is great! I have tried many serums that I've sampled through birchbox and I think this one made my hair the smoothest. And it smells great. For reference, I have long, thick straight hair.5
Love this Hair serum. It is light and does not make my hair too oily. Love the brand so it is no surprise that I love this serum. I put it on while I am blow drying.5
I don't typically use hair serum so I dont' really have anything to compair it to, but it was nice to try it out!3
In my opinion the product worked, but it is way too oily. Even just putting the product on my ends it made them oily no matter what.3
It is expensive for a basic hair serum, but I love the light scent it has and makes my hair feel smooth.4
Great smell, adds shine, and reduced frizz. I am probably going to try out a full size product in the future.4
This serum does the job. I just wished the sample was bigger to see if it's really worth need buying. I was only able to use it once5
I loved my sample so much that I have used all of it! It is so light weight and makes my hair look like I had a professional style it!5
I've used some other products from this brand but the price is SO off putting. This product didn't impress me, and though others have, none justify the price.2
