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 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
My hair is poker straight so this product is not useful for me. It has a smooth thick consistency which is nice.3
Nothing fancy here. I wouldn't use this every day. I didn't find if to perform any miracles3
I loved the way it smelled and made my hair soft ab andd shimmery I loved it5
A very moisturizing product -- definitely made my hair softer and silkier; the smell was fantastic!4
I was excited to try a product from Kerastase because I heard good things about the brand. However, the sample was very little for my long hair, and I could not tell if it was worth buying. I did not see big difference after use.4
