Birchbox Breakdown

If you’ve ever grown out your hair (or tried to maintain a long mane), you know how important it is to keep your ends healthy and strong. We like to stretch out the time between our salon visits with Kérastase’s Masque Cristal, a deep conditioning treatment specifically designed for long hair. It nourishes and protects strands (read: prevents split ends and brittleness) without weighing them down, leaving hair soft, supple, and full of healthy bounce.

How to Use

Apply a quarter-sized amount of product to wet hair, gently working into the mid-lengths and ends. Rinse thoroughly.

Great product, don't love the packaging

I love Kerastase products. I love the shampoo that accompanies this product and the masque was great, but I didn't LOVE the packaging. When applying in the shower, I'm much prefer squeezing it out of the bottle, opposed to open and exposed to the shower.

In the second go-round, I purchased the shampoo again, but opted for a bottled conditioner.

Strong scent
Sampled

I really wanted to like this product, but as someone with extremely sensitive skin, the fragrance was a little overwhelming. Take that with a grain of salt as I am at the extreme end of the spectrum of sensitivity.

Lightweight Hair Mask
Sampled

I am super surprised with how lightweight this hair mask is. This has been one of the only ones I have found that don't make your hair greasy. I have dry-oily hair, so its very difficult to find something that works. I noticed a difference to how soft my hair was, but it was not a dramatic difference. I think this would be good for like a once every week-few weeks treatment, and then you would notice a huge difference.

Amazing leave in hair masque!
Purchased

I have really oily hair and love this product. I usually put this conditioner on at night and leave it on all night. The next day I wake up and wash out my hair and it comes out so soft and shiny without making it look oily or weighing it down. The smell is also a plus!
