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.

didn't lather at all :(
Sampled

i was not too impressed with this shampoo but did like the volumizing kind from this brand. This particular one did not lather very well for me which is something i like and i did not find it to have much of a scent. Besides that, i didnt feel like my hair was clean afterwards so i wasn't a fan of this product

Did not rinse well
Sampled

For a clarifying shampoo, I thought this would rinse out well, but It did not. I had to follow it with another shampoo to get my hair clean.

Leaves My Hair Greasy After One Day
Sampled

I used this with my regular conditioner the first time and my hair felt greasy after my shower. The next time I just used the shampoo but it didn't make my hair any different from before.

Alright

It did not seem too different than any of the other shampoos I have used. Worked well in washing my hair but nothing special
