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.

Very Thick
Sampled

This is a nice clarifying shampoo. It is very thick so you do have to work it into a pretty good lather before applying it to your hair or else it will just stick to one spot.

Pretty good
Sampled

I like this, but it's a bit expensive. Would repurchase though. Smells good and leaves your hair soft and smooth and doesn't dry it out.

No 4 is the best!

I typically use the moisturizing No 4 shampoo and conditioner, but tried this one in a sample and loved it. Their products have a great scent and do the job with little effort.

Works Great!

I loved this sample of vegan shampoo. It is definitely thick, so make sure to use just a little and lather it into your hands before applying to your hair. I love the smell. Overall, this was a great sample.
