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.

I love the smell of this. I have over processed blonde hair and after using this shampoo for 1 week my hair feels great even when wet.

Nice scent

This shampoo does what it says - it's hydrating. I used it without a conditioner and my hair was great. It also smells lovely.

Woo

I have big frizzy hair and the product made my hair smooth and silky while also keeping it tame and not frizzy. I fell in love with the product with only one use! Must use :)

ok

This sample is good for travel but I don't care for the scent so it won't be replacing products I already use.

Hydrates without being greasy

I absolutely love this shampoo. I have thick wavy/curly hair that gets pretty limp if weighed down, but can get frizzy if not hydrated enough. This product leaves my curls looking great and my hair feeling soft - a pretty impressive accomplishment for a non-curly hair shampoo. Plus it lasts and lasts - I've used it every day for at least 2 weeks and have still not gone thru my sample (I have long hair).
Definitely recommend!
