Editor's TipEditor's Tip

Use Kérastase Bain and Fondant Chroma Captive in the shower beforehand for the ultimate three-step color-lock treatment.

Kérastase

Birchbox Breakdown

Unless you were blessed with perfect natural hair color and grays never sprout from your head (i.e., you're one in a million), you probably color your hair. Just as likely? Color fading and chemical damage. Lock color in (see ya, premature fading) with this hair mask, which preserves your shade and keeps tresses soft and shiny for up to 40 days.

How to Use

Apply a quarter-sized amount to wet hair, focusing on the mid-lengths and ends. Leave on for about three minutes before rinsing thoroughly.

Straw

Was super excited to get this in my box. I've always wanted to try this brands deep conditioner & now was my chance. The good: great sample size, beautiful package, decent smell and texture. Bad: Not sure if it locks in color, but can say it for sure sucked out the moisture. I noticed every time I used it, my hair seemed extra dry. I'd rather need to dye my hair often, then have it look like straw.

Nice product for color treated hair

I really liked this product for my slightly dry color-treated hair. Since the sample was a little small and I wanted to get at least 3 uses, I only used it on the ends of my hair. It smells wonderful. I would probably purchase the full-size but it's a little pricey for me.

I didn't see any difference after using product. The bottle is cute though.

masque

This is an effective product, without being heavy or greasy. Of the products I received this is probably the one I would buy.

It was ok

This conditioner was just ok to me. I have dry, color treated hair and need a more moisturizing conditioner. Worked good on my daughter's hair though.

Karastase Masque Chroma Captive

Really liked the texture and fragrance of this product. I have only used it twice and it's a little early to tell if it prolongs my hair color, but if it works I may have to purchase.

To expensive

I liked this product but I have found similar at a much better price. Other than that it was nice.

Kerastase is fantastic all around. Great products that actually work. Very pricy but well worth it.

Smell Great

Nice sized sample. It felt nice when I used it. I would have to use it long term to determine effectiveness.
