Born with naturally thick hair? Lucky you. Try the Kérastase Cristalliste Set for Thick Hair.


Birchbox Breakdown

Ever since we first spotted Blake Lively in “Gossip Girl,” we’ve been desperately growing out our hair to mimic her thick, gorgeous waves. (Years after the series finale aired, our strands are still in progress.) Of course, growing out our hair is easier said than done, especially for ladies with fine hair. Thankfully, the hair gurus at Kérastase have responded to our tress distress with this three-piece Cristalliste set—a special line of products designed specifically for long, fine hair.

How it Works

Long hair has specific needs. While conventional shampoos and hair masks can zap volume with their heavy formulas, the Bain Cristal Fine - Cleanse shampoo and Masque Cristal hair mask add incredible body and movement to fine hair. An oil-absorbing system removes dirt and impurities from roots, while naturally derived conditioning agents smooth and polish each strand. An infusion of aloe vera tames frizz and adds silkiness. To finish, the Spray à Porter texturizing spray creates soft, beachy waves any day of the year. Use it as a styling product on damp strands, or spritz generously to add volume to second-day hair.

How to Use

Apply a nickel-sized amount of Bain Cristal Fine - Cleanse to wet hair and scalp. Work into a lather and rinse thoroughly. Then, apply a quarter-sized amount of Masque Cristal to wet hair, gently working into the mid-lengths and ends. Let sit for 5-10 minutes and rinse. After towel drying, apply Spray à Porter to damp hair from roots to ends. Scrunch into beachy waves and let air-dry, or style as usual with heat tools. Can also be used as a texturizing spray on dry hair.

Hair Set

I bought this set after receiving the samples in my Birchbox. I love the shampoo and use it everyday it's perfect for my long fine hair. I was disappointed in the conditioner though. It has a nice light feel which would seem perfect for not weighing down fine hair, however its not very effective at detangling my hair. Perhaps the conditioner is more suited to someone who has fine hair that doesn't also have dry overprocess ends. I would purchase the shampoo again and I love the related leave-in serum (not in this set) but the conditioner is not worth the money.

Kérastase Cristalliste Set for Fine Hair

I really love this combo for my fine, dry hair. I love the mask. It really helped soften my dry ends! I would defiantly recommend this!

Very good overall

Smells lovely. Cleans and moisturizes well. I think it adds a little volume to my hair. I can go a day without shampooing and my hair and scalp don't feel nasty. Haven't tried the bonus Spray-a-Porter. I will probably buy again but want to try other Kerastase products too!

Great Value for the Price

Love the shampoo very sweet light scent. Gets my hair feeling super clean without feeling stripped of moisture.
I like the conditioner but I wish it were a tiny bit heavier. I have used other Kerastase conditioners in the past that I definitely prefer over this one.
The leave in spray is a nice bonus at this price point. I wouldn't order it on its own because I don't feel like it is really doing much. I do however enjoy the way it makes my hair smell.

great for long blonde hair!

I live in hawaii, where the humidity can really mess with your hair- but this has worked great. Light weight so my hair doesn't get weighed down, yet conditions enough so that I don't get the humidity frizz!

Been looking for Keratase in the states

I happened to purchase Keratase shampoo for colored hair at a Marshall's a year ago and it was great stuff. I searched everywhere to find more and that's when I learned it was not in the states and I would have to order from another country. I was so excited to see it on Birch site and I knew it was worth the price!! Great product!!!
