To extend the life of your (salon-given) hair color, start in the shower: Shampoo with Kérastase Bain Chroma Riche - Cleanse and condition with Kérastase Masque Chroma Riche - Treat before following with a dose of this styling aid.

Kérastase

Birchbox Breakdown

You’ve mastered the daily SPF routine—for your face. Next up: zeroing in on a protective styling aid that keeps your color-treated strands safe from UV rays. Kerastase’s rich leave-in cream is the ultimate defender—it restores moisture, blocks harmful rays, and keeps strands bright. Apply it daily and feel free to frolic outdoors as much as you like.

How it Works

This silky leave-in treatment targets the three D’s of heat and sun exposure: dehydration, deterioration, and dullness with hydrating ingredients and smoothing ceramides. Specialized UV filters block damaging rays, while also counteracting the effects of free radicals.

How to Use

Working from the tips up, generously apply two nickel-sized amounts to hair. Concentrate on extra dry areas and let the treatment sink in before styling.

Kerastase Chroma Thermique
Purchased

Great product. I usually use Kerastase Nutritive Nectar Thermique which is made by the same company, but decided to give Chroma Thermique a try. This is also a great product. I gave it four stars because it is pricey.

Works well
Sampled

It worked very well on my hair. It also smells good. I think the only negative is that it's pricey.

Great product
Purchased

I was introduced to this by my hair dresser and was super happy to see I could buy it a little cheaper at Birchbox. Works great, I use it every 3 shampoos or so so it's lasting a bit. But I wish it came with more product/was a little cheaper.

This is the stuff!

This is an amazing product! I have long,thick hair and this made my hair like budda (butter). It is expensive, but it's worth every penny in that it delivers salon results.

Makes your hair soooo silky!

I LOVE this product. Between blow dying and straightening, my hair gets frizzy and brittle very easily. Just a pea sized dab of this keeps my hair shiny and soft. The package size lasts forever, wonderful product!

BEST!!

It took me a while to get to this product sample, but once I did it was AMAZING!! My hair felt twice as strong and thick as ever. It's been thinning out and somewhat dry, but this product made a BIG difference. As soon as I get to it, I'm certainly adding this line to my routine in hair care.

Silky Smooth in the Sun

This product did great things for my hair. I got it right before spending a trip at the lake for a few days and it helped protect my hair from the normal drying and wear and tear that happens when I spend several long days in the sun. I also have hi-lights and I think it helped keep those tones brighter for longer!

Not for Thin Hair

I had been convinced by a stylist in my past life to purchase this product in its full size and I hated to see it in my box! This product stayed in my shower as a luffah paper weight of sorts. This just weighs me down and makes my hair feel limp. The only time I used this was as a once every few months start over product. NOT A FAN!
