Birchbox Breakdown

Even fine hair needs a good conditioner. This sulfate-free formula detangles and softens hair without weighing it down. You’ll be left with smooth, manageable hair that is noticeably fuller and more dynamic. Did we mention it also smells spectacular?

How to Use

After shampooing, squeeze out excess water from hair. Apply one or two pumps of conditioner (depending on length), concentrating on mid-shaft and ends.

hilarious price

the sample was fine. but it was a conditioner and frankly, a $10 bottle of w/e will work well enough for me. i just can't imagine what a $78 bottle of conditioner would do, but it's not this.

Not my favorite

This brand just isn't for me. I am not a fan of the fragrance nor do I think it's anything special compared to products I already use.

Does the job. Very overpriced.

Is a good conditioner but incredibly overpriced with a very poor sample size given in my box. Barely enough for one use.

Smells great

It smells great and works very well. Love this product. It is VERY expensive and with having short hair I wouldn't buy it. Other than that its great and anyone who cares about their longer hair should get it....if you can spend that much on it.

Not for $78 dollars

I used the sample that came along with the corresponding shampoo. Nice scent, rinsed clean. My hair had nice volume, felt really good, and smelled great. I cannot justify paying $78 dollars for 25 oz of conditioner though. It's not that kind of miracle conditioner!

Worst Conditioner EVER

I received a sample of this conditioner. For my hair, normal fine colored hair, most conditioners work. I would not pay $7 for this conditioner and Birchbox is asking $78.
Just ask for a sample before you buy.

I really liked this product

I got this in my mystery sample pack. I loved the smell and the way it made my hair feel! (I have very dry ends from repetitive highlighting and a naturally oily scalp) This product didn't weigh my hair down but still made it feel soft. The price is the only thing that gets me though. I am a cosmetologist and have a hard time justifying paying this much for less than a liter of product. (I can get puerology at the salon price for around $60 and it is an entire liter of product). Wish this was a little more in my price range though!

not a fan

I can't stand the smell. I feel like it dried my hair out a bit and just over all wasn't a fan of it. I will not be using this product again

not so sure about this scent

I love a nice conditioner but this smell just was not appealing at all. I really want to like it because I like the way my hair felt after using it but the smell just overpowered my liking it. I was really looking forward to it but...
