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 hair mask!
Sampled

I haven't used a mask in a while (just out of sheer laziness on my part), so I was so happy to receive this in my March sample box! Easy to use, and I loved the results. I don't color-treat my hair, so i was worried that my hair would feel weighed down or oily/heavy after the treatment..... it didn't and I loved how soft my hair felt!

couldn't really telel if it worked
Sampled

I got this product as a sample, and even though my hair is only shoulder length right now, I still couldn't even get a full use out of the sample packet I received.

On the plus side, it smells really nice, rinses out very easily, and I think it gave my hair a little added shine.

Nice
Sampled

For the two times I was able to use the product I thought it made my hair very soft. While I didn't have to use as much product as others my long, naturally curly hair still requires much more product than was provided.

Hair Masque
Sampled

The hair masque felt very moisturizing and my hair was extremely soft after rinsing, however made it very frizzy once dry. The smell is fantastic though

Not really sure about the product, but I didn't particularly like the scent
Sampled

Based on the sample provided, I honestly don't think I can really make a proper assessment about this product. It was creamy and felt like it was helping my hair; but once dried, I didn't really notice much of a difference in my hair. For the cost, I'm also not sure it's worth it either way.

I got a tiny sample in this month's box. This was a nice masque--made my hair soft and easy to style.

Worked ok, nothing special
Sampled

This did moisturize my hair but it didn't do anything super special. Also, the smell was pretty overwhelming.

Soft hair
Sampled

I generally don't use hair masks, but gave this one a try and really liked it. My hair was so soft and shiney after using it. It was a small sample, so only one use, but I may consider using hair masks from time to time in the future.

Average
Sampled

This did not do anything more than your average store bought shampoo. I also thought the smell was a little too masculine.
