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.

My favorite hair oil!!

Kerastase is the standard for hair oil, nothing is better. It makes your hair so soft, doesn't weigh it down, and it even smells great. Worth the price.

This hair oil is certainly one of the better products in this category.
Purchased

I have tried multiple similar products including in the Fekai line, Bumble & Bumble, Ojon, and Aveda products and though all are good products, I think this one has an edge in quality. Though it is more expensive, I think less is needed thus making it comparable in cost. I did not see as much benefit myself using it on wet hair(other products seem to be better) but for finishing and gloss, it is a very good product.

My favorite hair product by far!

I tried this at my hair salon after a cut. I love the smell and how lightweight it is. My hair feels and looks much healthier after using this for months.

Favorite hair oil hands down.
Purchased

I first encountered the Elixir Ultime at my hair salon, my hair had been a bit tangled after coloring, so the hairdresser pumped some of this onto her hands, massaged through my wet hair and after the blowdry--Voila! I immediately remembered the product name and purchased it off Birchbox. It's currently my favorite, and it seems it will last FOREVER. I apply one pump when my hair's damp and it makes all the difference.

Liquid gold

They pretty much had me at "Kerastase." I love everything they make. This hair oil can be used before shampooing as well as after, on wet or dry hair, and basically does everything but load your dishwasher. Shine, manageability, and softness galore, without weighing down hair. A little goes a long way. Pricey, but you only need 2-3 drops at a time so it lasts FOREVEr.
