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 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
I was surprised at how effective this product was, I liked the texture and how it tamed my frizz.3
I'm not usually a fan of hair serums, but this one smells great and doesn't make my hair look too greasy. I probably wouldn't purchase just based on the high price, but it is a nice sample.4
This stuff was ok but I don't think I could spend the money on it.3
I love this serum. I have a different serum from Kerastase and I love that as well. So lightweight and makes my hair super smooth! Also eliminates frizz and helps out my split ends.5
