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.

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!

Silky Smooth Hair!
SampledPurchased

I love this product. It makes my hair so silky and smooth. The smell is pretty great, too. It doesn't make my hair too greasy, either.

nice product, small sample
Sampled

i did like this, i thought it was interesting considering i haven't done a hair masque before, so it was nice to try. i'm not sure about the sample packaging because i really only got to use it once and noticed a slight difference in my hair, but would have liked more product to try again and see if there were longer effects.

Makes my long hair silky smooth
Purchased

This product definitely works--makes my long hair silky smooth and smells awesome (just maybe a touch on the strong perfumey side). I love this product, it is a large container that has lasted me a while, and I use it often after using my regular conditioner.

This masque left my hair feeling soft and well conditioned. It rinsed out fairly easily, and did not leave my hair feeling weighed down or greasy.

I don't get it

I was very excited about getting a free sample in my last purchase. The promise was almost too good to be true! Based off of most of the reviews, I thought I would be pleasantly surprised with the product. Unfortunately, not only did this product do nothing for my hair (and I mean nothing), it couldn't even replace my conditioner! I left it on towel-dried hair per the instructions, rinsed it off, and my hair felt dry and frizzy. So - basically it did nothing to nourish or protect my hair. I ended up using a blow dry oil and protectant spray and styled my hair as usual. Problem was, now my hair seemed more dry and breakable than when I started!

Great Stuff
Sampled

My husband is in the army (so busy and often gone for days or weeks at a time) and I've got a brand new baby. That being the case, I don't have a lot of time to get into the hair salon, so anything I can do to keep my hair healthy and looking good between salon visits is great. This stuff does just that and it's not greasy or heavy. It doesn't make your hair look like you've used a styling product, just like you've got healthy, naturally beautiful hair.
