I'm a minimalist when it comes to styling my hair, and the Living Proof Flex Shaping Hairspray  ($24) clearly shares my philosophy. This 3-in-1 spray can be used on wet or dry hair and it works as a styling aid, setting spray, and a finishing hair spray. Mist it on your damp hair before a blowout, spray it on sections of hair before you use a curling iron, and use it to finish any look. It's the only product I need for all my go-to styles, and it doesn't weigh my hair down or leave it stiff and crunchy. It can be brushed and layered to suit a variety of styles, so when are you going to take it out for a spin?
