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 hair oils. This was very good at controlling frizz and not making hair look oily.5
I have really long hair, and also split ends because of it. I regularly trim it, but I love the look of long hair, so never in great amounts. This product was amazing. It made my hair look very healthy, and felt like a little miracle. I certainly love the product, it is just a tad pricey for me.5
I really enjoyed using this product and I can say, for my hair type it did exactly what it said it would do!5
I love this serum. I have a different serum from Kerastase and I love that as well. So lightweight and makes my hair super smooth! Also eliminates frizz and helps out my split ends.5
I loved this product but will not be purchasing it.5
I was really surprised by how effective this product is, considering it has such a thin feel. It left my thick curly hair feeling bouncy, and lightweight, but with shine and form. Will definitely be purchasing in the future.5
I liked the way my hair looked after using the product. It is pretry pricey so I won't buy it right away.5
Pretty impressed with this product. I usually use oils because serums are a bit too greasy, but this one wasn't bad.5
The scent isn't overpowering, and it's moisturizing without being too greasy.5
Love the scent of this product. It worked great for smoothing frizz in my hair and adding a nice shine (but not greasy).5
