Birchbox Breakdown

At the end of a long day we could all use a fresh start——and the same goes for our hair. When product buildup and styling stress leave strands feeling and looking dull, this clarifying shampoo, subtly scented with white freesia, golden amber, and warm musk, gently cleanses without stripping moisture or color. Black currant and soy restore vibrancy, acai berry and vitamin C deliver youth-boosting antioxidants, oolong tea and Irish moss defend against environmental damage, and lemongrass and oatmeal gently cleanse and purify. This shampoo is also vegan-friendly and free from sulfate/sodium chloride and parabens.

How to Use

Squeeze a small amount (a little goes a long way) of the water-activated formula into the palm of your hand and work into a thick lather. Deposit the lather evenly through damp strands and rinse thoroughly. Use daily for best results.

Love love love

This shampoo leaves my hair feeling clean and smelling great. Really starting to become addicted to this brand. One thing I can complain is the scent is very mild.

Best clarifying shampoo!
SampledPurchased

I've bought this 3x now and forget how much I love it. When I go without it for a few weeks I can tell the difference it makes breaking down the build-up in my hair.

Clarifying Shampoo

I finally got around to trying this shampoo and I love it. My hair felt extremely clean after one use. My hair is fine and build up from styling products weighs down my hair quickly.

I want EVERYTHING I own to smell like this product!!! I honestly could care less if it were the worst shampoo in the world because it smells THAT good. But it is a love shampoo to boot! I just want the scent bottled....

I really like this product. I have oily hair, and use a lot of products to help with that.. I enjoy the scent and this is really an all around great product. I will continue to use it.

Excellent product
SampledPurchased

This product lives up to its promises. I live with well water that has tons of minerals in it leaving my highlights looking very dull. I wash with this and my hair is cleansed of the extra minerals and my highlights come back to there initial color. My hair also feels soft after using this ( a huge bonus because of our well water).

Great shampoo

This shampoo left my hair feeling super clean. I have really oily hair, especially at my scalp, and this shampoo kept the oil away a bit longer than most.

Just ok

Not a huge fan, didn't add much lift to my fine hair and the smell was too much for me. Felt the sample size was small. Probably not a future purchase.

Love it!

My hair was so silky and smooth after using this shampoo and the hair mask that came with it. It's much more expensive than most shampoo/conditioners I use, so I can't decide if the price will be "worth it" but I'm tempted to buy the full sized bottles because my hair looked so great after using it. Not dried out at all from the "clarifying" aspects.

Really love this one! First product ever purchased based off of Birchbox sample. Makes hair extra clean. Did not leave the hair smelling fabulous, but not bad either, just really no smell.
