Number 4 Number 4 Clarifying Shampoo

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.

Such a fresh scent (my bf loved it) and really leaves hair feeling light and airy.

Amazing
Sampled

I've been struggling with really brittle, dry hair for several months. Literally after one use, my hair felt healthy, smooth, and looked amazing. I didn't enjoy the smell of the product, but that isn't even a huge factor since it worked so well!

It smells great but not enough for a use to tell how well it works

Smells so good

I love how No.4 products smell. This was no exception! Made my hair soft and shiny. Felt like I needed to use a lot though to get it to lather a lot. Overall I really liked it.

At first I was thrown by the non-lathering quality of this shampoo, but once I saw that this was intended I liked the effect of the shampoo. My hair felt very clean and soft after using the product.

Nice

I really liked the feel of this shampoo, it didn't lather a lot but it had almost a sticky feel in your hair. It wasn't hard to wash out or anything, it actually felt really cool.
