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.

this shampoo did not lather well and did not make my hair feel clean.

Didn't like
Sampled

I had a few people tell me about this product and while I followed the directions, I needed almost the whole bottle to cover my scalp, there's no way that is necessary.

Aromatherapy for your hair and it looks good

What a great product. The scent is dreamy and the product feels good and makes your hair very manageable. All good things with this new product.

Sample wasn't big enough
Sampled

I have short but very thick hair, and the sample was only enough to wash half of my head.

Good
Sampled

No complaints about this as a shampoo. It didn't have a bad smell, lather nicely, and didn't feel like it stripped my hair. I don't use a lot of styling products in my hair so I don't typically use clarifying shampoos so it's hard to compare.

Feels great!!
Sampled

I've received the No4 products a few different times from Birchbox and I've loved each and every one of them. I love how my hair feels after. I just wish they were bigger samples, so I could use them more than once.

Smells Amazing
Sampled

This is the best smelling shampoo I have ever used. Super thick consistency so you don't have to use much to lather up, hair is super soft. I haven't purchased any full size items yet in 4 months but this may be my first purchase!

Great Product
Sampled

The low lather aspect of this shampoo threw me off a little while I was washing my hair, but I noticed how clean my hair felt rinsing it out. I followed up with the hair mask and noticed a huge difference right from the start. My hair felt soft and silky,tangle free and healthy; this continued all through styling and the whole day. And it smells great!
