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.

How it Works

L’eau de Mer™ uses vitamin B5 to condition hair and silicone to bump up the gloss factor, plus the brand’s patented Liquid Complexes™. Each of the four complexes is a different blend of natural ingredients, designed to 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 L’eau de Mer Hydrating Condition.

Good Shampoo
Sampled

I am always skeptical about hydrating products because I have very fine, thin hair which can get weighed down easily. This shampoo didn't do that and didn't leave my hair greasy looking like most other hydrating products do.

Hair feels like silk
Sampled

The shampoo makes your hair feel like silk after about the 4th washing, but the shampoo smells like rotten seafood.

Number 4 Shampoo

This has been a great shampoo sample and I like that Birchbox paired it with the matching conditioner. Both performed well.

Not for me

It works well, but for the cost there are plenty of other products that work just as well for less.

Smells great, cleans well - nothing overly special about this shampoo though

Lasting results

I shower in the morning, but by the evening my hair still soft and even lightly retains the nice smell from this shampoo and the separate conditioner. Most shampoos I've tried don't have day long results.

Pricey but good

This shampoo is awesome, it does a good job of cleaning my hair while also keeping my hydrated. It also has an even better smell but it is also very expensive.

Good product but no wow factor
Sampled

I really liked this shampoo-- I don't like shampoos that get to sudsy so this had the perfect amount of lather for me. I was not crazy about the smell and my hair did not seem remarkably different afterwards.
