After a good towel dry, get a long-lasting hold and finish with Number 4’s Firm Hold Gel.

Number 4 Hair Care

Birchbox Breakdown

Much like a dull conversation, dull hair should be avoided at all costs. This everyday shampoo (which does double duty as a body wash) deep cleanses and repairs damage while locking in much-needed moisture. The sleek pump dispenser adds instant style to your shower while ensuring you get as much or as little product as you need.

How it Works

Rich in vitamins and antioxidants, this clarifying shampoo restores health to all hair types. Black currant and soy add shine; acai berry and vitamin C deliver age-fighting antioxidants; Oolong tea and Irish moss defend against environmental damage; and lemongrass and oatmeal cleanse and purify.

How to Use

Apply one to two pumps of shampoo to wet hair and scalp. Lather, rinse, and repeat as needed. May also be used as an all-over body wash.

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
Sampled

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.
