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.

Great shampoo

This is a great clarifying shampoo. It smells fantastic and leaves my hair very clean. I would definitely consider purchasing a full-sized version of this since it works so well.

Whoops

So it took me two uses....without reading the label, to realize this is concentrated shampoo. Lol. But....it is very luxurious feeling, leaves my hair feeling very clean and even a bit thicker. Love it. Will be purchasing soon

Left my hair felling soft and manageable. Very expensive, but if only using once or twice a week it would last a long time because a little goes a long way.

It took me a while to get used to the scent but what really sold me was the effectiveness. My hair is soft and smooth after using this and I use a lot of product since my hair is fine and thin.

This shampoo smelled absolutely incredible and left my hair feeling soft, smelling great, and silky smooth. I felt like I was off on a tropical vacation somewhere! For someone with damaged hair, this stuff worked wonders.

OMG love this stuff. Used it once and the difference in my hair was amazing. I have a lot of color damage and its almost non existant now. This stuff is great.

I have become a huge fan of Number 4 products thanks to birchbox! The clarifying shampoo leaves your hair clean and soft, it almost feels as though you have also deeply conditioned your hair.
