Birchbox Breakdown

Sometimes the best treatments take time and maintenance, but in a 140 character-based world, sometimes we want a little more instant gratification. Once applied, this nourishing serum gets to work, reviving damaged, colored, and all-around unmanageable hair without weighing it down—for a smooth, shiny Instagram-worthy finish.

How to Use

Rub a few drops between your hands, and gently massage into hair and scalp. Can be used on wet hair before styling or on dry hair as a finishing touch.

This does a pretty good job at what it is supposed to do, makes hair smooth and soft. cant use for more than a couple days in a row or I start to get greasy look and I wish it smelled stronger.

A+

Although it's only a sample I loved every drop of it. The scent is refreshing and it doesn't leave any oily film.

Okay stuff

I like the way this stuff smells. But it left an oily greased feeling to my hair. Don't think I'll be purchasing a full size anytime soon.

The perfect finishing touch
Sampled

I love this product - I WILL be ordering a full sized bottle. I have corse, thick hair and it keeps my hair looking perfect - even when it's humid outside. I use it after my hair is dried, before I use a flat iron.

Good stuff but don't really feel the difference
Sampled

I liked this product. However, after using it a few days, I really don't feel any different with my hair. Instead, I see more of a difference when it comes to shine.

amazing

This serum does wonders for my hair, and is the best smelling hair product I've ever used. I'm definitely considering buying a full-size version of it.

OMG Fantastic
Sampled

Barely need any of it to make my hair super soft, silky, and frizz-free. Forgot to use it after I washed my hair today and you can definitely tell with the amount of frizz I have going on. Very light smell so it doesn't compete with anything of the other products I use.
