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.

Great stuff

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!

Not the best

I'm an avid supporter of Aveda products and this shampoo just didn't cut it for me. Glad to have it since it came in handy traveling for work... But I would not purchase the full size.

silicones

I gave this sample to my daughter because I do not use silicones in my curly hair. It smelled good. She seemed to like it.

Nice, clean shampoo

This shampoo had a nice, clean scent and kept my hair clean throughout the day. I didn't experience the oiliness that often comes at he end of the day. It was a great compliment to the leave in conditioner product also made by this company. Will definitely keep using it.

Eh
Sampled

I have used better shampoos that are made without all the chemicals like this one. It did not impress me or make any kind of noticeable difference to my hair. It did not hurt my hair or make it frizzy either. It was just blah to me.

All number 4 products are great!
Sampled

These products (clarifying shampoo, hydrating shampoo, and, the mask) are all well worth the price. They leave my fine, thick hair manageable and shiny, not to mention, great smelling!
