Number 4 Hair Care

Birchbox Breakdown

Whether your hair is over-processed and brittle or just chronically dry, this is the shampoo for you. The satiny formula is gentle enough to use every day and helps to soften and hydrate strands with natural essential oils and extracts. Free of parabens and sulfates, it foams into a rich lather that leaves hair soft and shiny. Vitamin B5 conditions hair and silicone bumps up the gloss factor, while the brand’'s patented Liquid Complexes help protect, purify, strengthen, and revitalize hair.

How to Use

The concentrated formula goes a long way. Depending on hair length and thickness, apply one or two pumps of shampoo to your and work into a lather. Work into wet strands and rinse thoroughly and follow with Number 4 Hydrating Condition.

Giving it a try.

I liked the fact that it lathered up really well, but the smell bothered me. Still, it did seem to moisturize my hair so I might try it again.

Shining Shampoo
Sampled

This was a great smelling, moisture boosting shampoo. I took it on a trip when I typically feel like everything is dry from flying and was pleased with the fullness my hair had, the scent of the shampoo, the texture it left my hair with.

Simple clean shampoo

Clean smelling and very easy to lather. Only a small amount emulsified in your palm goes a long way. Hair feels shiny and super fresh. Great basic shampoo that's no fuss or muss.

Nice Shampoo
Sampled

I used the whole sample. Liked it but nothing special that I would spend more money on. I worked well but nothing that a cheaper shampoo couldn't do.

Just another shampoo
Sampled

This shampoo was good, but it didn't clean my hair any better than the other shampoos I have used in the past. I would have liked to try it with the matching conditioner to see if they worked better together.

Smelled great!

I think it was a great shampoo. I could tell it was moisturizing, but hard to tell without the conditioner.
