Birchbox Breakdown

Our Miami-based friends told us that this multitasking styling foam helps their hair look pristine through a summer’s worth of sweltering heat and tropical humidity. Naturally intrigued, we decided to investigate it for ourselves, and we’re pleased to report it works in all climates. The body-boosting formula provides flexible hold and can be used to define curls or fight frizz. Bonus: It also prevents heat and sun damage and extends the life of your color with loads of nourishing botanicals.

How to Use

Dispense a small amount of foam into hands and distribute through damp hair, starting at roots for added volume and working through to ends. Blow-dry or style as usual.
