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.

Great shampoo
Sampled

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.

Best Clarifying Shampoo

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.

Fine, but not great

This shampoo was just fine. It got the job done, but I had to use a lot of it to get a decent lather. It didn't feel very nourishing or moisturizing. Won't be buying a full-size product.

I like to use this product in between my salon visits and the day before I go. I've enjoyed this product and would consider purchasing this in the future.
