Number 4 Hair Care

Birchbox Breakdown

This isn’t your Aunt Edna’s helmet-in-a-can hair spray. This flexible-hold, water-free spray will make your mane will be as high and mighty—or as subtle and sophisticated—as you’d like, while still allowing for natural movement (and no flakes or frizz).

How it Works

Flex-net resins provide flexible hold and shine (and make it easy to brush back into place the next day) while humidity resistance technology reduces frizz. The brand’s Liquid Complex Culture ™ protects from thermal styling and UV rays, preserves color, hydrates, and strengthens. All Number 4 products are 100 percent vegan and free of harsh stuff like sulfate and sodium chloride, gluten, and parabens.

How to Use

Hold the can evenly about 10–12 inches from your head and spray.

Great hold

I was skeptical about a non-aerosol hairspray, but I really like this one! It has a great hold, not sticky or clumpy. You can still comb through your hair if needed after using. I would like to purchase this product.

Love it!
Purchased

I've tried no. 4 pump hairspray. And I loved it! But I think I like the aerosol can even better... So light and airy and keeps hair in place without the frizz! Sprayed some in on a humid day and my hair stayed put. Definitely a good investment

The BEST hair spray ever

My hair is fine and curls do not stay in long after I get done curling my hair. For the first time in my life, after using this hair spray, my curls last all day long. This product is simply amazing!!

Not what I thought I was getting but did the job
Purchased

I thought I was purchasing the Non-aersol Mighty 4 brand that I had a sample of. Oops, I really need to pay better attention next time. This hairspray did the job, a bit heavy for my but I did enjoy the hold of my curls.

Smells great

Love it! The smell sold me. It doesn't have the harsh smell like other hair sprays. Great hold, but not so much that it stiff and doesn't move.

Lightweight and Smells Glorious

I can't imagine ever wanting to use another spray (except maybe the non-aerosal version). This is perfection. It really feels so lightweight yet is just enough hold. And it has a wonderful scent!

Amazing Hold!

This product has amazing hold! I did not have to use much at all to obtain the style I was going for. The spray also did not leave my hair crunch at all. I was able to use the hair spray, style and brush it all out with gloss and hold.

great hold

This product does the job and does not make your hair hard as long as you don't spray too much. Not a bad smell and does not flake!
