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.

Love this shampoo

The shampoo size was small, but I used it for a week. I have long hair so i shampoo my scalp and then condition the rest of my hair so it doesn't dry out. My hair was soft and shiny where it's normally an ehh brown. This is going to be a staple in my shower!

Nearly Perfect

I love everything this product stands for, especially being vegan-friendly. It also doesn't strip color which is amazing. The only complaint I have is that the scent is a bit strong. It is very musky, and it reminds me of fresh pauperie. It a nice scent, just a little much for my hair.

ok

Cleans the hair fully. Would not be good for repeated use because it tends to dry your hair. Good to use once and a while for build up removing.

I loved this product! It truly gets all the 'gunk' build up out of my hair. My hair is fuller, smoother, and softer every time I use it.

This shampoo smells absolutely heavenly, and it leaves my hair feeling fresh and clean. I use a lot of hair products, so this shampoo is great because I feel like it really gets rid of all the product build-up. My hair looks great and is much more manageable after one use. I just wish it wasn't so pricey...but I would recommend!
