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.

Doesn't lather well
Purchased

This shampoo does a great job cleaning my hair, but only if I use half of the bottle, which takes forever to pump out. The shampoo is way too thick!

A clarifying shampoo that does its job
SampledPurchased

This is the second of two No.4 samples that I've gotten and I have been highly satisfied with both. When I received the clarifying shampoo, I was in the middle of trying to repair my hair. This shampoo did the trick. It completely cleaned and cleansed my hair while leaving it soft, shiny, and healthy. I'm definitely keeping some on hand so that I can give my hair a more thorough clean when I can feel the product building up.

Decent

I used this a few times and it was pretty good. It washed my hair just like it was supposed to lol. It was really thick which threw me off, but I enjoyed the scent and was satisfied with the product. Probably won't be buying though.

I wouldn't buy the full size product
Sampled

I have lots of long, wavy hair and I couldn't really see/feel a difference after using the sample. Although I must note, that two shampoos (what it took to finish the bottle) really isn't enough to judge if a shampoo works for your hair or not.

Fresh, gentle, clean...AMAZING
SampledPurchased

Clarifying shampoos are often way too heavy in the stripping department. This, however, is just gorgeous. It smells gorgeous. It cleans my hair without making it squeaky. I have nearly platinum blonde hair (colored, not natural) and this is super gentle, super fresh, and absolutely amazing.

Cleared up hair
Sampled

Liked this shampoo! I don't often use clarifying shampoo, but thought I'd give this a shot. It smelled great and definitely cleaned up the build up on my hair. It didn't make it feel too stripped of natural oils, either.
