Number 4 Hair Care

Birchbox Breakdown

Situation: Your hair is dry and brittle and you’re a few weeks (perhaps a few paychecks) away from a trim. Solution: A super-hydrating leave-in treatment. We’re partial to Number 4’s™ Lumiere d’hiver Reconstructing Masque because it infuses moisture and protein (the two things that hair needs most!) into strands, leaving our hair soft, shiny, and in far better shape than it was before.

How it Works

Soy protein works to reconstruct and strengthen hair while natural conditioners like shea butter, jojoba seed oil, and sunflower oil nourish and moisturize. Don’t forget about the silkiness factor — for that, there’s silicone polymer, which smoothes and detangles.

How to Use

After shampooing, wring excess moisture from hair. Apply evenly to hair starting at the ends and working your way upward to your scalp. Wait for two to five minutes, then rinse thoroughly.

Amazingly awesome!!
Sampled

One of the best products I have received thus far during my one yearsubscription to Birchbox! Light weight, non oily, and leaves my hair looking super awesome and feeling soft. Not to mention I do not have a single tangle when it comes time to comb out my hair! A+ for this one!

Great Mask
Sampled

Even though this sample was only one use, I could tell that my hair felt softer and it left a nice pleasant smell that was NOT over powering. I enjoyed this mask and will definitely consider it for a future purchase.

Love love it!

This product smells amazing. The sample size was small. I could only use it once. But I do love that my hair smells and feels great. It's so soft.

Works Well
Sampled

It helped my tangled locks brush out well. I thought it smelled nice without being too over powering. The only negative is I have pretty sensitive hair and if I used this too close together it would easily make my hair look greasy. It was a little heavy and sort of weighed my hair down.

Works well but strange smell
Sampled

I like the way my hair looked after using this product, but it had a weird chemical smell. After it was rinsed it was OK but didn't like that while I used it, it didn't smell very pleasant.
