Apply Number 4™ Blow Dry Lotion to wet hair before styling, and follow with hairspray for hold and shine.

Birchbox Breakdown

It’s rare to find a hairspray that’s great for our hair and the environment. This non-aerosol mist fits the mold: 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. Best of all, the earth-friendly formula doesn’t contain any harmful chemicals. In fact, all Number 4 products are vegan and free of gluten, sulfates, and parabens.
