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.

So-so product

I really like the Super Comb Prep & Protect from Number 4 Hair, so I was excited to try this product. I did feel it removed build up from my hair, but it also made my hair pretty flat. It also made my scalp itch! As with most sulfate-free products, it was also difficult to work into a lather and I had to use a lot of product to get sufficiently wash my hair.

So-So
Sampled

I liked the after affect of this shampoo, but it was just so so for me. I didn't like how thick it was and how hard it was to work into a lather before I washed my hair. I use other products that get the same after affect that I like better.

Probably Won't Purchase
Sampled

This shampoo wouldn't lather, which I found weird and unsatisfying. I never knew if I was using the right amount, and because I have extremely thick hair, I always felt like I was missing sections. The scent is good though, and it did make my hair feel very soft.

Still hate the smell
Sampled

I've tried other products by Number 4 through Birchbox and I really, really dislike the smell. I thought the different product lines would have different smells but they all seem to smell like rancid chocolate. The shampoo worked fine, but nothing special. Will not be buying from this company.

Just ok

For some reason the shampoos that you have to emulsify fist bother me. I feel like i still need to use a lot granted I have very long and medium thickness hair. The scent was just ok. I don't think it's for me.

Loved the smell
Sampled

My favorite part about this shampoo was the smell. Otherwise, it worked fine, was a bit thick for a shampoo and took a lot of time rubbing together in my hands to make it really workable. Also felt like I needed to use a lot despite instructions indicated otherwise. Left my hair nice and soft.

Shampoo says Clarifying shampoo but I didn't feel that it really cleansed my hair.

Not Crazy About It
Sampled

I like the smell of this product but that was about it. The shampoo wouldn't lather which meant I either needed to use a lot to get all of my hair or I felt like I was scrubbing plain wet hair. Not a fan of this one.

This didn't lather well and so with a lot of hair, it made it difficult to get my whole head covered.

Just Ok

I wasn't overly wowed on this one. It worked fine but didn't foam up as much as I would like. The scent was ok, but it is pretty overpriced.
