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.
Smooths hair and adds shine, but be careful to not use too much and make your hair greasy. Also I love the smell of this product.4
I'm not a big user of hair serums so I wasn't really sure how this compares to other serums but it seemed to do the job! It also smells really nice!4
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
Helped with frizz and made my hair super soft. Very light weight.4
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
I didn't notice it improve any frizz or shine, but I found that it made my split ends look a lot better! However, for the price of it I'll just get a trim lol.3
I applied this to dry hair (as per the instructions on the Birchbox card) and it left a gummy, heavy feeling to it. I use a very very small amount, knowing I have fine hair, and I only used it on the ends. I will try it again on wet hair before I blow dry to see if that improves. It smells great and it has a nice texture, it just didn't do the job for me.2
IT did nothing for my hair... feels weightless but also 15 minutes after i put it on... you cant even tell I did anything3
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
