Kérastase

Birchbox Breakdown

From heat styling to chemical processing, there isn’t much we haven’t subjected our hair to in the pursuit of beauty. And my, how our poor follicles have suffered. Fortunately, this ambrosia-like hair treatment revitalizes even the most parched strands and frayed split ends. In addition, it provides protection against heat styling and even improves the performance of your tools.

How it Works

This magical product relies on three key ingredients. Royal jelly, a rich “bee’s milk” that is fed to a hive’s queen bee extend her lifespan, has an incredibly high moisture content as well as nutrients and antioxidants to keep hair healthy and strong. Xylose enhances hair integrity and shine while guar gum smooths down flyaways and paves the path to soft, silky hair.

How to Use

Apply a dime-sized amount of product to slightly damp, towel-dried hair. Start from the ends and work your way upwards, massaging gently. Finish off by styling with a blow dryer or a flat iron.

Best heat protector out there!!
Purchased

I love everything about this product. It smells heavenly. You only need to use a dime size amount (for shorter hair) so although it seems like an expensive product, it will last forever. After blow drying my hair looks shiny and healthy and full of body. I have tried other heat protecting products but I always come back to this brand because it is by far the best.

LOVE!

I absolutely love this treatment. I'm a 50 something woman with dry hair. I was hooked after the first use and will never go without it! This makes my hair less dry and much more manageable.

Best one ever!

It is worth every penny, it leaves my hair soft, manageable, shiny, it also gets rid of frizz (which is what I was really looking for). Bottom line I love this product.

Nectar of the Gods
Purchased

I have been impressed with Kerastase products (love their shampoo & conditioner) and this product was no exception. I apply this with Oribe's Royal Blowout for blowouts that are sheer perfection every time. Just a note, though: I've used this when air drying with less spectacular effect. Definitely for use with a blow dryer.

Great for My Dry Hair
Sampled

This product was perfect for my dry hair. It has a pleasant smell which is important to me as I am sensitive to odors. This seems to rejuvenate my drier hair and keeps it nice and soft!

Have been using consistently for nearly 2 months and have noticed a difference in the condition of my hair after heat styling. Will definitely repurchase!

OMG BUY THIS!
Purchased

Oh my dear, sweet baby Jesus.. if you have dry hair that you style often, there is no better product than the Nectar Thermique! I swear, you could put transform a bird's nest into spinning thread. The bottle is about the size of your hand and is expensive, but it will last a long time. I'd even pay $60 for it, now that I know how awesome it is. I've had my bottle for 6 months now and will probably last me for another year. A little dab goes a long way and it works the best IMO on wet hair. If you're going to use heat styling, make sure you use this! Everyone always compliments me on how healthy my hair looks after I use this stuff. My boyfriend can run his fingers through my hair. My hair doesn't get the burnt smell after I dry it and straighten it. I LOVE IT. HOLY GRAIL HAIR PRODUCT. THE END.

A MUST for heat styling!
Purchased

I cannot and will not go back to my spray on, drugstore heat protectant after trying this product.
This doesn't merely protect your hair from heat, it treats it with heat activated moisturizers!! My hair feels softer and looks shinier after styling, which is unbelievable :)

So Great
Purchased

I should not be allowed to touch my own hair. I blow dry, curl, and bind it up with ties all the time. Unfortunately, I cannot afford to pay someone to do my hair for me every morning. Such is life. I tried this product on my hairdresser's recommendation, and, lo and behold, my following visit was the very first time she did not give me a sideways glare. This product is expensive, but it works really shockingly well. Worth the bucks.
