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.

Could take it or leave it...

The smell of this shampoo was nice but afterwards my hair felt stripped of moisture. I didn't feel that it provided any restoration or flare for my hair.

Good Product
Sampled

At first, I only used a small amount but it didn't clean well since I have such think hair and a lot of it. It made my scalp itchy at first, but when I started using more the itchiness went away. It makes my hair really soft and I feel like I just left the salon with the smell.

Love the smell!

Mostly I loved the smell of this shampoo. I thought it did a nice job cleaning as well, though it doesnt lather at all, which felt bit strange at first. but the smell was worth it !

Great Shampoo!
Sampled

I took this along with me on my recent Florida vacation and really enjoyed it! The amount was perfect for the 8 days I was gone (in fact I still have a decent amount left, as a little goes a long way). It took me a try to realize the importance of emulsifying it so that I could work it through my hair, but that's on me for not reading the directions :) Smelled great and left my hair clean and easy to manage.

great shampoo
Sampled

I got about two uses out of this bottle and thought it was a great shampoo. My hair, which is usually pretty flat, actually felt volumized after using this product. It is still pricey for a shampoo so I'm not sure I will purchase.

Love it!!

I love this shampoo does not have sulfates in it. It doesnt foam up but I learned no sulfate = no bubbles. So that is a good thing. The smell isn't my favorite but I really like that it cleaned my hair without stripping it!

Best Shampoo I've ever used!
Sampled

My hair has never smelled so good or felt so light after washing. It does a great job of removing oil and buildup. I only wish it wasn't so expensive!

Great To Use As A Backup
Sampled

I use this while showering at the gym and it works for that. The texture reminds me a bit of glue and is thicker than your normal shampoo. It does the job, but I wouldn't trade in my regular brand for it.

This is make your hair feel shiny and light, taking all the build up off your hair from product over time. Use it once in a while.
