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.

Not as good as the pump
Purchased

I love the non-aerosol version of Number 4. I bought this thinking I'd love it too and I DO but the non-aerosol holds much better for lifting your roots! Still very pleased though and will buy it again!

Best hair spray ever!

This hair spray is incredible! It's is SO effective and long lasting. It can be a bit crunchy, so a little goes a long way. Great scent too. I'm so excited I got this in the travel size pack.

Sorry

I tried this and found it to be much heavier than the aerosol sprays I usually use. It also doesn't keep my flyaways in place for very long. I also didn't care so much for the scent of it. I think I'll stick with aerosol sprays. Sorry.

Works Great

Great product!! It holds curls pretty well and doesn't make them stiff! I must say I do like the erosol cans better though.

LOVEEE
Purchased

I love this hairspray. It smells so nice and the smell is there all day! I love getting little whiffs of it throughout that day. This hairspray holds without being too sticky or stiff, which I really love. Nothing more unappealing than having stiff, untouchable hair or losing curl, volume, etc because the hairspray won't hold. Overall I love this product!

Hair spray
Purchased

I bought this because I love hair spray and my boyfriend does too! He likes a hard holding hair spray while I like one that holds but is flexible. I really liked the feel of this but I also felt like it took a lot to keep my fly aways down and my boyfriend didn't like it because it turned his hair white from the amount he had to use to get the hold he wanted.. I haven't purchased this product again and most likely won't

Good, flexible hold that'll hold up all day
Purchased

I love the number 4 volumizing shampoo and this is a great styling buddy. I have a LOT of hair but its very fine and this helps give it a little air and volume without being stiff at all. Also like the smell, one of my favorite things about this brand. Definitely earned its place on my vanity.

Meh...
Purchased

I absolutely adore No. 4's product line, but this hairspray just isn't doing it for me. It provides a moderate amount of hold, but my biggest issue is that it remains tacky until you wash it out despite how much or how little you use. I'll usually curl my hair and re-use the curls the next day, but the general stickiness of this hairspray just puts me off. You definitely can't run your fingers through your hair after using this or you can feel the hairspray on your fingers afterwards. Not something I would repurchase.

For my hair style, this works well. Just a few passes and it holds my hair all day. Plus, it smells fantastic!
