Birchbox Breakdown

This decadent conditioner helps to bring dry, over- styled hair back to life. It’s loaded with moisturizing natural ingredients that calm frizz and restore fried ends and it also protects from future damage. Don’t tell our hair stylist, but this product is the reason we can go so long in between trims!

How to Use

Use on clean, damp hair. Depending on hair length and thickness, work one pump through the ends and mid-length of strands. Rinse completely and style as usual.

Best Conditioner I've Ever Used
Purchased

I've tried a lot of different conditioners to deal with my fine, curly, frizzy hair. This is the only one that manages to make my hair feel soft and well-conditioned without it looking greasy or getting a weird buildup that weighs my hair down. I'm addicted

Great for coarse hair
Purchased

I have thick coarse, color treated hair that is curly/frizzy underneath and have tried all kinds of high end conditioners. I found this brand a few years ago and was blown away at how well it moisturizers my hair and have been a loyal user ever since. Great to see Birchbox carrying it. The hydrating shampoo is a must too!

Ok

I wish the sample was a tad bigger. It wasn't enough to coat my entire head. So, I used it on my ends, since it's suppose to repair splint ends. Not sure if it did as it says, but at least my ends felt soft

Most hydrating conditioner ever used
Purchased

I was hesitant in using this when I recieved a sample until I read it was free of sulfates and parabens. So glad I tried this. After only one use it made such a difference in my hair that I ordered the full size bottle. Very expensive however a little goes a long way and the bottle has lasted a long time.

AWESOME CONDITIONER

I cant say enough about this shampoo and conditioner. The smell, the lather and the results. I have color treated hair and this is some of the very best product I have ever tried on my hair. My hair was silky - easy to comb through. The fragrance lasts a long time. LOVE LOVE LOVE NO4.

This conditioner is great. I wish there was a little more in the sample though, because I have long hair. The smell is great too. I recommend this product!
