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.

one of the best Kerastase products
Purchased

I heard a rumor they were discontinuing this in the US so I bought two more bottles. I love this and have at least three bottles at my house right now. You don't have to heat style your hair to get the great benefits. This, and the Elixir Ultime (the light pink one) are my favorite Kerastase products! Never can have or apply too much :)

Great for Damaged Hair

My hair is damaged from straightening and coloring. This is the product that gave back the life of my hair. I would highly recommend this treatment.

Great Stuff

I am very impressed with this product specifically and generally any Kerastase product. They all do exactly what they say they are going to do, and I appreciate that when I purchase something.

Should feel lighter
Sampled

I wish this leave in product was a bit lighter so that I could use it every day. I don't want to have heavy hair weighed down by product when I am out.

Wow
Sampled

I received this awhile back as a sample in my birchbox and just now tried it today. I put it in my hair before blow drying and I could already tell a difference in my hair. It was not as frizzy and when I straightened my haircut was so smooth. Would love to purchase but this will have to be a splurge so for now it will sit in my favorites and I will treat my sample as liquid gold.

Amazing Multi-purpose Product!
Purchased

I just reordered this product after enjoying my first bottle so much! This product not only smells great (not over powering) but works so well. I am a natural blonde who gets highlights often to keep my hair brighter and lighter. The chemicals from highlights (even though I get salon services at Aveda Salons which uses natural less harsh chemicals) can be drying! My stylist recommended this to me as we are friends and is something she uses. My hair has changed dramatically; stronger, more shine, and faster drying time. I use this product when I air dry, blow dry, before other styling such as curling, or even when I scrunch my hair! It works great in addition to other curl enhancing formulas adding more shine and less frizz!

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

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