Number 4 Hair Care

Birchbox Breakdown

It’s rare to find a hairspray that’s great for our hair and the environment. This non-aerosol mist fits the bill: It’s full of natural botanicals to nourish strands, and it provides the strong yet flexible hold you need to tame flyaways and support updos, even in high humidity. Best of all, the earth-friendly formula doesn’t contain any harmful chemicals. All Number 4 products are vegan and free of gluten, sulfates, and parabens.

How to Use

After styling, spray product 10–12 inches away from hair for natural, lasting hold.

I love this spray! Makes my hair shiny and holds my curl or fights the frizz!

Holds up all day
Sampled

Number 4 Non-Aerosol is a pretty decent hairspray. I'm not a huge fan of non-aerosol hairsprays at all. I usually find that they wet my hair and weigh it down. Number 4 however breaks that cycle. With alcohol as the 1st ingredient instead of water, that "wet" flattening effect does not occur. It held my "up do" all day and into the evening, yet it remained touchable and soft. If you prefer a non-aerosol hairspray this one is great. It might even make me a converter. Who knew?!

Earth Friendly...

I recently used this hair spray on a trip to Miami, Florida. I like that it's lightweight, great for the environment, and it has natrual botanicals in it.

hated it
Sampled

The smell, the smell, the smell. The product may have been not bad but I can't get over the smell. Just a few squirts and that odor is all you smell for the whole day, and that is no exaggeration!

It was a little drying in my hair. Made my hair feel like straw and I only used a little.

crunchy (in the right way)
Sampled

It leaves your hair soft and pliable but is crunchy in the hug a tree kind of way! I love that this is an earth friendly product. Most non aerosols don't perform but this one totally fit the bill.

Decent hairspray

This hair spray had a mild hold and left hair feeling light. I don't use hairspray often but this seems like a good one

LOVE

This hairspray smelt great! I wish I had a bigger sample to use it more than a few times, but for the most part it held my hair. I have thick hair and it worked well.
