We all know vitamin C is helpful when we feel a cold coming on, but this powerful antioxidant also defends hair’s natural strength for beautiful, healthy locks.

It's a 10®

Birchbox Breakdown

On a scale of 1 to 10, this leave-in treatment obviously gets…a 10 (we were going to be dramatic and say an 11, but, while true, that’s just confusing). Needless to say, we’re big fans. This miracle conditioner, which boasts 10 different benefits, eliminates frizz, restores shine with a few quick sprays, protects hair from all of those heated styling tools you love, and prevents split ends. Use it alone or as a restorative styling product.

How it Works

The conditioner’s natural ingredients restore moisture while adding strength and shine for instant silky hair. Green tea leaf extract shields hair from environmental damage, and panthenol, a provitamin, strengthens and softens hair and prevents split ends.

How to Use

Spray one or two spritzes into the palms of your hands, then gently run your fingers through dry, styled hair, right down to the ends (it basically works as a pomade or styling crème). For extra shine, apply to wet hair, then blow dry and style as normal.

Tames my dry and frizzy hair

Love everything about this except the smell! It's a bit strong and perfume-y. The only product that reliably detangles and smooths my super thick curly and dry hair. No frizz, but keeps my curls soft!

Great for curly hair
SampledPurchased

I live in a very humid place and my hair tends to get really frizzy. This stuff is great on my hair, both reducing the frizz and detangling. I just wish it didn't cost so much, but of course I'll keep buying it. I even bought a travel size to pack in my carry on bag.

Great product
Purchased

This is an excellent leave-in product. The smell is nice, but most importantly, it really does leave my hair a lot less frizzy. I used it on towel dried hair out of the shower, and let my hair air dry, and it looked really good afterwards -- healthy! I can also cop to using it on a very rushed morning when I didn't have time to wash my dirty hair. A few light spritzes of this, and I didn't look quite as raggedy (I don't know if that's really one of the intended uses... but it works!). I first came to know this product because a stylist used it one time, and I'm really glad, because it's phenomenal.

If I didn't reliably get so many great hair tonics in my Birchbox, I'd have bought this multiple times instead of just once. So glad I decided to get the full-size after trying the sample. I used it every day in the winter and it kept my hair looking great!

A multi-tasker that works

I use this as a heat protectant and frizz fighter. It's so multi-purpose and easy to use that it's worth throwing out a ton of cheaper products. It's also not super heavy and keeps my medium thickness hair from being too big or too flat.

Re-Discovered FAVORITE
Purchased

Back in high school, I used to steal the 10 Miracle Conditioner from my mom (she would always hide it from me) and since then I had kind of forgotten about it. One night I was browsing through birchbox online and I couldn't have been more ecstatic to find this on here! After using it just once, my hair already feels as smooth and healthy as it used to when I used it years ago. I couldn't ask for a better hair product, especially because it is an excellent detangled and it smells great!

I use this on myself and my daughter. I love it! It's a great detangler for her delicate thin curls and it helps my coarse straight hair feel softer and more manageable. I also use this as a thermal spray-in when I straighten my hair.
