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.

Number 4™ Clarifying Shampoo - 8.5 oz
Sampled

This worked very nicely on my thin hair. It left it soft and shiney. The shampoo is much thicker than normal shampoo, I believe because it's very concentrated. I just put a dime size in my palm and then worked it into a lather in my hands before adding to my hair.

AMAZING!

This shampoo is the best clarifying shampoo i've ever had! It's not overly drying, but doesn't leave my hair feeling oily. Wish it wasn't so expensive though!

Didn't like
Sampled

I didn't like the way this left my hair feeling. I don't use a lot of product in it so maybe I found it to not really be necessary because I guess you're supposed to use to clarify your hair of all that product build up. I'd rather stick with my regular shampoo

Works well

I thought this was a good clarifying product. Although I don't always put a lot of product in my hair I though me hair felt lighter and more fluffy

Smells great!

Honestly i can't make up my mind on this product because the sample was so small i barely got two uses from it. I can say it did have a pleasant smell.

good but not great
Sampled

I prefer a more moisturizing shampoo. This product got the job done. I was glad to have the corresponding hair mask to add the moisture I needed. The scent was to perfume-like for me.

I love this shampoo. I have used only one other clarifying shampoo and though it worked well it did not leave my hair feeling healthier then before which this did do.
