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.

Fresh and Clean
Sampled

Has a fresh scent and clean feel. I am using all natural shampoo and conditioner now, though, to eliminate whatever toxins I can in my routines.

Great For My Hair!
Sampled

I love this product! It has a lo-lather formula so your hair doesn't dry out. My hair felt light and bouncy and it was definitely more manageable. I loved using this in place of my regular shampoo! It didn't leave much of a fragrance, which was fine because I was too happy with the way my hair looked and felt.

Smells great

I wanted to like this product because it smells so fantastic, but I felt like it made my hair feel very weird. Even after conditioning, it still felt kind of knotted and hard to brush through.

Great for curly hair
Sampled

I have a ton of curly hair and I completely loved this shampoo, especially because it's sulfate-free. A small amount went a long ways, even with my thick hair. It made my hair extra soft and kept the curl alive.

Overwhelming scent

I liked what the shampoo did for my hair, it added nice volume, but the scent was too overwhelming for me.
