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 results

I have natural curly color treated hair. I am growing it out and I put this on my hair dry and worked it in and left in on for an hour. After rinsing it off and fluffing the natural curl in, I dried to with a diffuser on low. The results were strong healthy Whiney hair and the color really glowed! I love this stuff!

Not All Kerastase Products Are Created Equal

I usually love Kerastase products and use a few religiously on my fine, color treated hair. This product, however, is a joke. It's thick, sticky and doesn't coat your hair very well or leave it more nourished. I bought it from a salon and wish I hadn't. Waste of money.

Smells great and works well

I got a free sample of this product with a purchase. I have long, naturally curly hair. I am always trying to find a product that will help control frizz and make me ends look healthy. This mask has a very nice fragrance and applies well. I felt like it made my ends feel better and my hair softer.

Left hair feeling limp and greasy

I love hair masks! I was really looking forward to trying this after reading some of the reviews. After giving this a shot I was very dissapointed I looked like such a grease ball!! Definitely not for me!

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.
