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

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.

Ok

Pretty good shampoo and was complementary to the conditioning mask. I didn't find anything particularly unique but enjoyed the sample that I received.

Refreshing

This shampoo really seemed to cleanse and purify. My hair tends to get oily so I used this every couple of washes interchanging with my other shampoo. Nice scent as well.

Love it!

This shampoo is great!!! It smells good and I noticed a difference in my hair after only one use. It didn't leave my hair feeling weird like other clarifying shampoos have in the past and my hair feels so clean!

Too greasy
Sampled

I really did not like this shampoo. I had high hopes for it, but it bizarrely worked the opposite for me: instead of clarifying, it left my hair extremely greasy.

Love the smell and texture of this shampoo! It's my new favorite shampoo. Leaves my hair feeling very clean without stripping it. Great with the matching hair masque too.

Number 4 Clarifying Shampoo
Sampled

It is a good idea to use a clarifying shampoo to alternate with regular shampoos. White freesia (ohh la la) musk (a favorite) and other scents combine in the wonderful fragrance of the product. It will renew your hair, and you'll be glad!
