Birchbox Breakdown

As the years go by, it isn’t just our skin that starts to show our age. Our hair follicles become weaker and more porous with each passing year, leading to everything from breakage and thinning to overall dryness and dullness. That’s where this hydrating hair and scalp mask comes in. Its targeted formula helps reverse signs of aging to leave hair softer and stronger. Designed to be used weekly, it’s great for ladies of all hair types and textures.

How to Use

After you get out of the shower, towel-dry your hair and smooth on a small amount of the mask, starting from your scalp and working section by section. Let the mask sink in for five to ten minutes. Step back in the shower, and wash away with warm water, followed by a rinse of cool water to seal in shine.

My Hair Loves It!
Purchased

I almost hate to admit it, but I spend about $100 or more on my hair every month to get it colored, cut, and blow dried. It's my one splurge.

My hair used to be very dry and brittle until I found this product. Kerastase does everything it promises to do - my hair feels and looks great since I've been using this.

It's added to my list of hair splurges - it's definitely a must have if you're of a certain age and color your hair!

perfect conditioner

I have long straight hair, not super fine, but definitely no where near course. This conditioner was the thing that finally got me to wash my hair every other day.
I was a daily washer before I found this. My scalp gets greasy, but my ends are dry. This conditioner strikes the perfect moisture balance. I use it daily.

Meh, only ok
Purchased

It makes my hair reasonably soft, but I haven't seen any long-term benefits. It hasn't improved the thickness of my hair or the number of strands that fall out. Not worth the price.

My hair is so soft

I normally do not use a rinse or mask. It I love how my hair feels with this product. I have been using every other hair washing.

Just ok
Purchased

I purchased this product because it promised to help my dry, "aging" hair. First of all the smell was not so great. Secondly, I don't think it worked all that well. Honestly, I prefer the Kerastase Chroma Captive product.
