Revitalize parched strands and frayed split ends with Kérastase Nutritive Nectar Thermique - Protect.

Kérastase

Birchbox Breakdown

It took us a while to hop on the hair oil bandwagon, but boy were we missing out. This lightweight elixir is fortified with a unique combo of four essential oils to leave strands super shiny and manageable—whether your hair is curly, straight, or in between. Plus, we can use it as a pre-shampoo treatment or leave-in conditioner. What more can a girl ask for?

How it Works

A hair care all-star, this elixir nourishes our locks with a blend of antioxidant-rich camellia, argan, maize, and pracaxi oils. The pump dispenser allows for mess-proof applications, and we love how the weightless formula isn’t sticky.

How to Use

Smooth one to two pumps into damp hair before shampooing or blow drying. Alternately, work through clean, dry hair as a leave-in treatment.

Cyclopentasiloxane, Dimethiconol, Zea Mays / Corn Germ Oil, Argania Spinosa Oil / Argania Spinosa Kernel Oil, Camellia Kissi / Camellia Kissi Seed Oil, Pentaclethra Macroloba Oil / Pentaclethra Macroloba Seed Oil, Linalool, Alpha-Isomethyl Ionone, Limonene, Coumarine, Benzyl Alcohol, Parfum / Fragrance.

I can't live without this stuff!! I have naturally wavy very long hair that can sometimes get a bit crazy and frizzy. This amazing product keeps my hair healthy, shiny and under control!

Fairly heavy oil
Purchased

I've been trying to work on how much of this to use and I can't figure out a way to use it that doesn't weigh down my hair. I like Kerastase products but this one is tricky.

This stuff is expensive but worth it. I love the way it makes my hair feel and it keeps it moisturized even during the dry chicago winters.

Great Product, Great Smell!!

I love this oil bc it has a super lightweight texture and it smells absolutely amazing. It also gives you hair great shine. This product is a bit on the pricy side, but it is totally worth it.

Best hair serum out there
Purchased

I've tried a hair oil/serum from pretty much every brand out there, and I always come back to this product. The price point is a bit higher than other high end brands, but a little bit goes a long way. I'm still working on my bottle that I've had for a year, and I use it every day. It smells great, doesn't make my hair greasy or stringy like some other serums, and effectively softens and controls the humidity in my fine hair.

Effective and concentrated

I love this hair oil when my hair is on the drier side, especially when I've processed or heat styled too much! One pump is all I need and I apply it through wet hair prior to blow drying. On particularly frizzy days I'll take the tiniest amount and smooth it over dry hair, starting at my wars and going down (avoiding my scalp!) since I bought this, they came out with oils for fine hair so when repurchasing, that would be my first option.

Love This

Silky and nourishing, this product is amazing for thick hair in need of a boost. I struggle to find products that leave my hair feeling healthy and not oily. I would recommend this product for anyone with thick/ long hair in need of some TLC.

Love the smell

I purchased this after getting a sample from the birchbox pop up shop. Molly suggested I try this instead of Moroccan oil or macadamia oil since I have fine blonde hair. It's amazing. Smells great and doesn't leave my hair looking stringy like other oils do. I use it before I wash my hair if I'm going to air dry and after I wash my hair if I'm going to blow dry. It's pricy but lasts a really long time.

it's alright

I found the smell to be pleasant and the product was easy to distribute through my hair. It was lightweight but I could not tell that it had actually done anything in terms of shine and manageability.

Not a keeper
Purchased

I have slightly coarse, slightly wavy hair that needs an oil or silicone based product applied before blow-drying it straight. (Otherwise, my hair has lots of fly-aways and tends to look slightly frizzy). I bought this product hoping it would give my hair a nice gloss, but instead, it left it rather limp. I tried using it several times, using a slightly different amount each time, but did not see a real difference. If you are looking for a product that is nourishing AND adds bounce, I would recommend the Agave Healing Oil Treatment (also sold on the Birchbox site!). I'd like to wrap it up by saying this product *may* work better on a different type of hair - I've seen reviews online with pics of people with stunning results - but for me, I found the Agave product more effective.
