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 love the way this product smelled and made my hair feel. It's perfect for last minute fly aways and finger combing our curls5
I loved this stuff and it definitely made me feel as elegant as a queen. It was light weight and smoothing, but nourished the dry ends. I have been dying to try this product and I will definitely be purchasing it!5
even though it was an oil it was not greasy at ALL!!! SO HAPPY i received it!! it was amazing Will definitely think about purchasing it in the future. It added a LOT of shine (But not the gross oily shine) and my hair looked really smooth. very satisfied!!5
I was highly surprised by how much I enjoyed this product. It left my hair smooth and light weight. I would highly recommend this product and plan to incorporate it into my normal hair routine.5
I usually use Moroccan oil in my hair before I dry it so I'm pretty used to using hair oils. I really liked the way it smelled and it did make my hair feel really smooth! I like this brand a lot but I think I'll probably stick with my Moroccan oil.5
This product is seriously amazing! I use a pump or two before I dry my hair! I have long fine hair but A LOT of it! This adds the perfect amount of silkiness & shine!5
I loved the way it smelled and made my hair soft ab andd shimmery I loved it5
I don't use hair serum very often at all but I really should! I have curly, sometimes frizzy hair that could really use some shine and taming! This product definitely provided that! It smells really good and it's so lightweight that I didn't even have to wash it off of my hands after putting it on the ends of my hair. It really made my curls shiny, less frizzy and more controlled, and kept them feeling light and fresh! Didn't weigh my hair down at all. I used it after my hair had air dried almost all of the way and applied it just to the ends, after I used my normal leave-in conditioner and curl spray. Love it!5
I like the product overall but the sample is so small.5
This product made my hair shiny and did not weigh my fine hair down.5
