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 serum was okay. It smoothed my hair, but I already use another hair serum I really like and it will take me a long time to need more.4
I was delighted to see a Kerastase product in my October box, I have heard much about this brand but could never afford to actually buy anything! I was certainly not disappointed after I tried it for the first time, this serum is a definite new favorite of mine. My hair is long, color-treated, and is pretty abused. This serum did a wonderful job taming my frizzies and left my hair smooth and shiny. I applied a little extra to my ends because they need all the help they can get. My ends were a lot softer and didn't feel like straw after using this "miracle" serum.5
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
