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.

Smells ok and functions as a shampoo. Nothing special.

Great Product!

I took this shampoo with me on a trip. I was nervous to try a new shampoo while away from home, but it was great. My hair felt very moisturized and there really was no need for conditioner!

Great product!

I loved this shampoo! It smells great, and I normally need 3-4 pumps of conditioner to satisfy my thirsty hair ( I know that's way more than I actually need, I just can't help it). With this shampoo, I almost didn't need conditioner. My hair was shoddy and smelled great all day!

best shampoo ever!
SampledPurchased

i have really thin hair that gets oily if i skip a daily shower, and this shampoo made my hair feel thicker after one use. it feels like theres a soft shield over my hair after it's dryed and styled, even after everyday use!

this is also the most expensive shampoo i've ever bought, but it was so worth it.

not for my hair
Sampled

I did not like this shampoo. It made my thick hair feel greasy. I had to rewash my hair with a different shampoo. I would not buy this product.

pretty good

I like this shampoo. It doesn't lather like most shampoos but it still leaves your hair feeling really clean and fresh.

Not for me

This shampoo was not for me. It made my hair feel really brittle and the scent was too much.

surprising shampoo!
Sampled

i'm very snobby about shampoo - and thought there was no way i was going to like this. it was wonderfully conditioning - such a nice surprise. has a nice smell. doesn't lather very well - so takes a lot of product if you have thick and/or long hair.

Average shampoo
Sampled

I definitely appreciate the fact that this shampoo is vegan-friendly and sulfate/sodium chloride free. That is huge for me personally. But that being said I really didn't like the way it smelled. Personally I'll just stick to using my WEN-like product.

Loved the Scent
Sampled

The smell alone is heavenly. It worked very well on my fine, thin hair, giving it a lot of volume which is what I always look for in any shampoo. A++
