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 like this because I felt like it added lightness to my hair. Will definitely purchase this sometime in the future.4
This product left my hair soft and shiny. I will not purchase it though due to cost and I use a similar product.4
Left hair shiny and not weighed down. Worked pretty well.4
This serum gave my hair moisture and got rid of frizz5
It does its job well! I have curly, semi-frizzy hair and this contained it and gave just enough shine.5
I have oily hair and this product just weighed it down even more. I used it once and passed it along to my sister to use.3
It did a pretty good job of reducing the frizz! It smells fantastic. I'm not sure it added much shine tho...4
I love the scent of this serum! It smells like a pricey hair salon in the best way possible - fragrant and kinda perfume-y. It also leaves the ends of my hair very smooth and shiny. If only it wasn't so expensive, I would definitely purchase it.4
Works really well on my hair. Only needed a little, even for long hair. Smells nice.5
Love this hair serum. I apply it after blow drying/styling my hair to my ends. Keeps them from looking brittle and dry, and instead leaves them weightlessly shiny5
