For soft, healthy locks pair with Number 4’s Lumiere d'hiver Reconstructing Masque. The rich conditioner adds a serious dose of moisture to dry strands.

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 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.

This product does not have a very strong smell to it. It is a very simple, not overwhelming product that does the job of cleaning your hair.

Meh

I mean, it does what it is supposed to do... gets your hair squeaky clean. It foams alright and smells OK. I think I used to much though, because my hair rebelled against it in the next few days!

Felt different, in a good way

I liked this shampoo and felt that it indeed was like a different kind of shampoo product. I'm not sure my hair looked different after but it did feel like it gave me a thorough clean.

Great for color treated hair

I have platinum blond hair that I am constantly adding wild colors to. This shampoo really helps me even things out between color choices. The smell is great and doesn't leave my hair feeling stripped.
