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.

Not for colored hair, y'all.
Sampled

Generally speaking, if you have colored hair, any shampoo that says "clarifying" in the name is not your friend. I've got blue/purple hair at the moment (which has faded into a silver) and try to go at least a week between shampoos. I'll rinse in the shower, but I let dry shampoo do the dirty work between proper shampoos. When I finally go to clean my hair, there's a solid amount of product built up on my strands and I need a good scrubbing to get it all out and start fresh. Enter Number 4 Clarifying Shampoo. This product does what it claims - it clarifies the crud right out. I don't know about using the tiny amount recommended, but I usually emulsify shampoo before applying to dripping wet hair, so I feel pretty confident that I'm getting the most out of it - if it still feels dirty after the first shampoo, I just repeat the process. All that said, yes, some color does leave my hair, but right now, I'll take clean hair over intense color.

Definitely Clarifying

They're not lying when they say this stuff is concentrated! It gave my hair a great deep clean. Definitely an easy product to work into any routine to remove product buildup.

Worked wonderful! Loved that it was a multi-use sample and could really tell that it worked on my hair. Wish the conditioner came in the same sample package.

This shampoo has really bring my hair "back". I have been color treating my hair for about 15 years and this is the first shampoo and conditioner combo to really bring the shine and softness back.

Need more then a little; smells weird

I really felt like I needed two palmfuls of this to clean my long hair. Hard to lather. It did clean my hair, but I didn't enjoy using it.

Okay

I received this shampoo & conditioning set in my box. I realize they are clarifying products but they were too harsh for my color-treated hair.

meh

This product is meh. My hair doesn't feel like it is being washed when i use it. It says not to use a lot but I never feel like I'm using enough. Doesn't feel super clean after either. Love that is is vegan.
