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——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.

Ingredient rich clarifying shampoo
Sampled

Love all the ingredients in this shampoo. I like a clarifying shampoo once a week to help reduce build up due to hairspray and other products, so I enjoyed receiving this in my box.

Rich formula

This shampoo I actually preferred as a body wash. It was a rich texture that lathered really well. A little bit went a long way and had a nice scent.

Love this Shampoo
Sampled

I know this shampoo is supposed to really clean your hair and get rid of any build up of product... but I mainly love this because of how soft it makes my hair. It feels so moisturized after I use it.

Great Shampoo!
Sampled

My hair felt so clean after using this! Usually when I use a heavy-duty shampoo, it leaves my heair feeling very brittle, but with this shampoo, it was very managable and soft.

Effective product but pricey
Sampled

I do really enjoy this product, and the nice sample size has allowed me to use it several times, but the high price is holding me back from ordering the full size. I do feel that it cleanses my hair in a way that removes product buildup without stripping the hair (I color my hair red, so this is a big plus), but that can also be done with cheaper alternatives. If I was a rich person (sorry to say it like that), I could see this as something I'd have in my shower constantly, because it really does work.

Number 4 clarifying shampoo

This shampoo is nice, gets out some/most of the grease out of my hair, yet i feel i can get something just as good if not better at target.

Product did as stated and left hair feeling nice and clean, removing any residue from previous shampoo/conditioners. My hair felt lighter which is a big deal as I have long thick hair!
