Number 4 Hair Care

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.

A little goes a long way!

I have really thick hair and am used to using a lot of shampoo but you really don't need a lot with this product! The smell is nice and fresh and my hair felt really clean after using it!

Nice shampoo but wouldn't use daily
Sampled

I liked the feel and the smell, but not sure I would use this more than once a week as it might strip my dry, colorized hair

This product really cleaned my hair without stripping it and drying it out further. Smells good too! Would definitely purchase again

This shampoo is awesome! You don't need a lot , but it still leaves my hair feeling super clean. My hair is really thick and coarse (and most shampoos leave a little bit of residue) but lately it was been soft and smooth with no residue left behind.

This is an amazing shampoo. I loved the scent and it definitely left my hair more smooth. I think it does what it says--removes product buildup.

I love the smell of this shampoo! Definitely listing it in my shopping list. It comes out pretty thick, so just a little blob goes a long way and foams up quick. The freshest after-feel!

I got this in my March box and I'm late to try it. But it is awesome! I also got the recovery mask, great product line! I am so pleased with this. I didn't need a lot. I could feel it really clearing up my scalp. My hair didn't feel heavy afterwards, and it smells great!
