If your hair is fine instead of thick, help it stay long and healthy with the Kérastase Cristalliste Set for Fine Hair.

Kérastase

Birchbox Breakdown

As anyone born with a thick head of hair knows, there’s a delicate balance between rocking an epic mane à la Lorde and looking overburdened like Cousin Itt. Luckily, we’ve found a trio of products specifically designed to add lightweight movement and volume to thick, long tresses. Inspired by “Gossip Girl” star (and wavy-hair goddess) Blake Lively, Kérastase Cristalliste products will give your strands movie-star-worthy body and shine.

How it Works

While conventional shampoos and hair masks can zap volume with their heavy formulas, the Bain Cristal Thick shampoo and Masque Cristal hair mask add incredible body and movement to thick 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 Thick to wet hair and scalp. Work the shampoo 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, and then 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.

Shine shine shine!!!

I love love love this product!! However I feel like it is being falsely advertised. It seems to be more of a cosmetic product rather than a treatment. Adds a ton of shine without weight.. People with thick unruly hair may be disappointed that it doesn't do more.
