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.
The product is a bit lightweight for my thick hair. LOVED the smell though.4
I would use this product every day if it weren't so expensive. I thought it did a great job smoothing out the damaged ends of my hair. I also liked the smell and thought it was nice and lightweight. Just wish I could afford it!5
my hair was sooooo silky and shiny!!! I absolutely love that it is so lightweight and makes my hair shimmer.5
I have fine straight hair so serum tends to just add to the greasy look of my hair. This did tame some frizzies and added shine, just have to be careful not to use too much
I have long, fine blonde hair (no color treatment) and this is great if you blow dry every day. Not heavy and makes my ends very soft, even when they're dry and in need of a long-overdue haircut ;)4
This serum left my hair looking shiny without weighing it down or feeling sticky.4
I loved this hair oil right up until I looked at the price. This is the exact type of product I use, and I like that I really didn't have to use much of it for it to be effective, I am just not sure that it does anything superior to my drugstore oil.4
I love hair oils. This was very good at controlling frizz and not making hair look oily.5
I have really long hair, and also split ends because of it. I regularly trim it, but I love the look of long hair, so never in great amounts. This product was amazing. It made my hair look very healthy, and felt like a little miracle. I certainly love the product, it is just a tad pricey for me.5
I really enjoyed using this product and I can say, for my hair type it did exactly what it said it would do!5
