If I had to only use one hair product for a year, this would be it! I use wet, dry, and/or as a overnight treatment. Makes my crazy, thick, unruly hair manageable and soft. Love, love, love!

Amazing

This product is amazing! It's lightweight, not greasy and I can't live without it. It makes my fine, straight hair really smooth and shiny. Plus it smells amazing! Definitely worth the price.

Straight-haired girls need hair elixir?!
Purchased

I have fine, straight hair so I have always avoided heavy products. I need volume, dang it! I almost threw the sample away when I got it in my Birchbox. I didn't know what to do with it! I'M GLAD I DIDN'T. I didn't realize that my straight hair could go from blah to bombshell with a little help from this serum! I didn't even know my hair was mildly frizzy until I used this product. I love it! I use it after I wash my hair or smooth a tiny amount over my ends after I curl my hair for extra smoothness and shine. Love it.

Amazing

People rave about Kérastase and now I know why. Never before have people stopped me unsolicited to compliment my hair, and I couldn't keep my hands off if it!

Great shine!
Purchased

My stylist has been using this product on my hair at the salon so I decided to take the plunge and buy one for myself. It adds a lot of shine and helps tame flyaways. My stylist suggested that I use 1/2 a pump on my hair (I have a lot of thin hair, medium-long). I gather my hair in a low ponytail and apply the product from the top of the ponytail to my roots.

Shiny and smooth

I have short, fine hair and I love this product. A little bit goes a long way for smooth, shiny, soft strands. I use this right before styling and I love the result - it makes it look like I just had my color done even if it's been a few weeks since my last treatment. I look forward to using this product for a long time.

Miracle worker!

I had never used a hair oil before I received this product in my Birchbox, and I've never looked back since. This transformed even my bushiest, frizziest, most slept in hair into a sleek, shiny, and manageable mane! To top it all off, it has a lovely scent. A staple in every woman's hair arsenal - or at least mine!

wish it wasnt so expensive

It is very lightweight and you can use it everyday. Just after using it a few days i was having people ask me what I was doing differently.

Not greasy!

I have tried other hair oils (some as Birchbox samples) and this one is the best. I have thin, dry hair and other hair oils make my thin hair greasy looking. This does not and it cuts down on the frizzies! So happy I got this in my Birchbox as I would not likely buy it to try on my own.

I love this product. It works better on wet hair and smells amazing. A little goes a long way. I wish it came in a travel size so I can refill it while traveling.
