Post lather, spritz strands with a leave-in conditioner like Number 4 Super Comb Prep & Protect.

Number 4 Hair Care

Birchbox Breakdown

At the end of a long day we could all use a fresh start—the same goes for our hair. When product buildup and styling stress leave your locks feeling dull, use Number 4™ Clarifying Shampoo, subtly scented with white freesia, golden amber, and warm musk, to gently cleanse without stripping moisture or color.

How it Works

Rich in vitamins and antioxidants, this clarifying shampoo restores health and shine to overworked tresses. 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 one pump (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.

makes hair soft!

I really liked the shampoo, my hair felt very clean and was so soft after using it, and it smells so good! But honestly, I can't see myself spending that much money on shampoo.

Awesome

My hair is looking fabulous! I have wavy, frizzy, fine hair- basically your nightmare. If I put any product in- it gets oily and limp- if I dont, I look like a poodle. This shampoo saved my life! I don't use any other products anymore- no conditioner, no leave in treatment- nothing. Sometimes when I start to use a new product, my hair looks great after first wash and then goes back to its unrooly ways- not this time! It is looking better and better, feels healthy and I finally feel I found the right product for me- hallelujah!

Good shampoo

It works well , and it smells really nice. It is just too expensive to buy though I would like to.

This bad boy is super concentrated

A little goes a long way. THis shampoo is super concentrated and I like it. Makes me feel as if I'm really washing all of the gunk out of my hair.

Number4 Clarifying Shampoo

I truely liked this shampoo and used it sparingly only because the sample wasnt very much. Would like to say that I would purchase it again but I like to try shampoos more than 2 times before I buy.

Shampoo

This shampoo smells really nice and my hair felt clean but not over-dried as you get with some shampoos. I would definitely purchase if it were priced more in line with high-end drug store brands.

SO Good

Paired with the mask, it is amazing. Not paired with the mask and just paired with your average conditioner, still amazing. My hair has never looked better!

LOVED IT!

Left my hair feeling soft but not limp! Smelled great and just didnt leave the build up that regular shampoo does. The ony real downfall is the price. I was ready to buy a bottle but cant see spending that kind on money on a 25 oz bottle.

Number 4 Clarifying Shampoo

This is a great shampoo for me because I use a lot of product in my hair. My hair feels great after using it but it is pretty expensive.

March Birchbox

Received this in my March box and I feel in love with the scent. I was happy to hear that you can use it as a body wash as well. Great product; left my hair smelling great and looking shiny and bouncy.
