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.
This was a nice lightweight serum that added a lot of shine to my hair. I preferably serum from a different brand though4
This stuff smells great and definitely adds shine to my hair, but I think the full size is just a bit too expensive. I'll stick with my drugstore serum for now.4
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
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 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
I've always been curious about Kerestase products, so I was excited to see this sample in my October box. This product made look shiny, less frizzy, and and smell is great! Will probably purchase when my sample is gone.4
This product did make my hair softer, but I'm not sure how much control it did for the frizz in my hair. It smells good though!4
I have highlighted hair and if I skip a day washing it, this is great to smooth out the ends. The sample was small and the little cap might have worked better as a pump, but that would be fixed in the full size product.4
I've been getting into hair serums/oils lately and was excited to try this one. It smells great and hydrates the ends of my hair.4
