You can use this mild shampoo every day without worrying about drying out strands. For best results, follow with L’eau de Mer Hydrating Condition and use Lumiere d’hiver Reconstructing Masque once a week.

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.

Smells SO GOOD
Sampled

I would buy this shampoo for the scent alone. But, it also left my hair feeling really, really clean. I could use this a couple a times a week for the rest of my life.

Just Alright for Number 4 Line
Purchased

After receiving the Clarifying shampoo in my BB, I splurged on this. I didn't think I would use the clarifying one enough to justify buying the full-size.
I enjoy the smell actually, unlike some other reviewers.
What I didn't like is that compared the clarifying shampoo, I needed much more product than I expected to cover my head (this was one of the main reasons I bought it).
Secondly, I do think the price point is high like most have pointed out. My first bottle came with a malfunctioning pump, and BB staff was extremely kind in not just sending a replacement pump but an entire replacement bottle too, which actually made the price reasonable to me. Otherwise, no way.
Lastly, I find that I'm having trouble making shampoos stretch like I used to. I can go maybe 3 days with a lot of dry shampoo, whereas I used to go 3 no problem. Not sure if this is hormonal, weather, etc. though.
I'll be looking into the reconstructing masque next!

Love the feel, hate the scent

I can not get past the smell. It reminds me of old grandma perfume. I did use the shampoo in conjunction with the sample conditioner and it left my hair feeling nice and manageable. Great sample size provided. Just not my cup of tea for scent....

clarifying shampoo that doesn't strip your hair!

Great telling shampoo, didn't strip my hair. Left it feeling clean and soft. Generous sample size. Definitely recommend using with the conditioning masque which moisturizes and repairs hair, leaving it luxurious

Great scent

This shampoo has a lovely scent that I've come to enjoy a lot. It lathers well. Very much considering buying a full version when my current shampoo runs out. It leaves my hair feeling very soft

I was so excited that this shampoo was paraben and sulfate free because I hate using harsh chemicals in my hair. This shampoo is so gentle but still makes my hair feel healthy and clean .
