Why choose a two-part treatment? Keeping the ingredients separate until right before you mix them helps ensure that the formula stays pH-balanced and doesn’t lose its potency over time.

Birchbox Breakdown

In an era that prizes freshness above all, it makes sense that we’d hold our hair products to the same standard as, say, our daily dose of green juice. This easy-to-whip-up treatment from the pro salon brand activates right before your eyes, so you know that it’s working at peak levels right when you apply it. And yes, we’ll admit to a somewhat geeky fascination with watching the chemical reaction unfold. The gluten- and paraben-free formula goes to work immediately to repair years’ worth of hair damage, leaving strands lustrous, hydrated, and full of healthy bounce.

How to Use

After you shampoo, squeeze a generous 1:1 ratio of both formulas into your palm, mixing them into a foamy, whip-like mask. Work evenly through clean, damp hair, focusing on the ends. Leave three to five minutes before rinsing thoroughly. For best results, we suggest using Duosity once or twice a week.

cool in theory

It was fun to mix it up and see the reaction. But did I see any real difference in my hair? Not really.

Favorite New Product!

I highly recommend this product. When I got the sample I was skeptical as to how it would work, but with my first use I was hooked. I was able to get a few uses out of the sample package even though my hair is most of the way down my back. I ordered the full-size product shortly after and it lasts quite a long time. I like the fragrance and how great it makes my hair feel.

Super soft hair

Kept it in my hair while I showered and left my hair feeling healthy and no weight down either. Great for longer hair that's prone to damage and breakage.

Damaged Hair's Best Friend

This is BY FAR my favorite product that I have received through Birchbox. My hair grows really fast and is really thin. Therefore, it's constantly breaking. This is one product that actually feels like it's doing it's job. My hair feels silky and looks so much more healthy after using. I usually get compliments on my hair after using this product, which is unusual for me. I would definitely check this out if you have issues with damaged hair
