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 have long been a fan of Kerastase products, and this one is a wonderful one! it's so soft and smooth going on and it makes my hair feel incredible. I have long, fine hair and this really does the trick!5
I was referred to this product by one of my friends who always seems to have great hair - we have different hair textures, so I was excited to see similar results when I used the product in a specific way. Both my friend, and myself, get the best results when we use this product mid-way through blow drying our hair (when the hair still has some moisture, but is moderately dry). When used this way, my hair ends up being incredibly silky and smooth - it eliminates the frizziness that my hair normally has, no matter how long I straighten it. If I use the product outside of blow drying it, however, I do feel like it gives my hair a greasy look. Point being, if you find the best way to fit this into your hair routine, the results can be fabulous!4
This product has been on my wish list for some time now. The first time I used this I fell in love! It smells wonderful and really smoothes everything down without being too greasy or heavy. It's a tad pricey but I think it's worth it.5
I have tried so many shine serums and Kerastase Cristalliste Lumiere Liquide is by far the best! It does not weigh down my fine hair. The light scent is fantastic and it gives lots of shine! I highly recommend this shine serum!5
i have really long and thick hair and was worried i would be done with this product in a week. however, a little goes a long way with this product and it's extremely long lasting! one pump is ACTUALLY enough! i get dry ends very easily, but this product has protected them and they look noticeably better after one week of using this product.5
This product does what it is supposed to and smells great. However, I still love the original Kerastase oleo-relax Serum. I think it works better and comes in a bigger bottle too!4
Best hair product I've ever got from birch box! I love this so much and want to use it everyday...but it's a little expensive!5
I use this product daily in my hair right before I blow dry. Everyone always asks what product I use for no frizz/volume and this is it! My hair is almost down to my hips, so the product helps with split ends. It really does look like Blake Lively hair whenever I use it.5
I am in agreement with the description — I love Blake Lively's hair and I would use any product she recommended. This product definitely captured her effortless waves. I love it.4
As a person with very long hair, I'm used to having to ignore the "dime-sized dallop" of shampoo/conditioner... or any hair product for that matter. But this syrum truly does bring meaning to a little goes a long way! A very small drop works wonders for my long hair and doesn't leave it greasy. Great product!4
