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 Kerastase! This product was amaaaaazing! Smells great! Smooths frizz! Adds shine! Nourishes hair! I mean there is literally nothing not to love about this product! Obsessed!5
This was good but there are a lot of other options that are better/cheaper in my opinion. I use a hair serum constantly and this one seems to be fine so I wouldn't not try it but know that for the price tag it isn't anything special.4
Will definitely purchase - my hair was so shiny after! A little heavy at first, but washes out nicely.4
I have short hair so I used a very small amount and I was pretty pleased with the product. Not sure I will purchase due to price and I already use a cheaper product that works as well5
I have never used anything like this before and I was every happy. My hair looks great. I would and will tell my friends about this product.5
I own a few products from Kérastase and every single one of them have proven positive results on my fine, sometimes lack luster locks! LOVE this product and I highly recommend it.5
This was a nice product. I don't use hair serums too much - I am very simple with how I style my hair. But this product was nice - nice clean scent and easy to use. It didn't leave a sticky residue like some products. :)4
I like this product but it smells like cheap hair spray. Also, it's a bit steep in price.3
This product makes my hair shiny, but unfortunately weighs down my baby fine hair. Smells nice though.3
I generally use a hair serum the days that I wash my hair. I like this one, I just think the price is too high.4
