According to celebrity hairstylist Jen Atkin (the creator of Ouai), Ouai Soft Mousse, $28, is ideal for anyone with hair that's both flat and difficult to control. It calms frizz while giving hair lots of bouncy fullness.

Alterna Thick & Full Volume Mousse, $28, contains a special marine complex that plumps hair while making it incredibly strong to protect it from styling damage. Plus, it has special color protectors to help keep your color bright and shiny.

Superstar hairstylist Oribe is the king of big hair, so you can image he took the creation of Oribe Grandiose Hair Plumping Mousse, $37, very seriously. And this formula does everything: It holds a style, builds tons of volume, controls frizz, moisturizes with vitamin E and smells like heaven.

Another problem with the crunchy old mousse formulas: If you brushed your hair, the product would get white and flaky -- and nobody wants mousse dandruff. Orlando Pita Play the Great Inflate Air Whipped Styling Foam, $28, is the opposite in every way. It's designed to have memory to hold a style for days yet it's soft and light enough you can brush out said style. It creates volume and shine while managing frizz and feeling like nothing -- it's the mousse of a new generation.

Designed specifically for aging, thinning hair, Living Proof Timeless Plumping Mousse, $28, can triple the overall volume of your ponytail. The results are soft and touchable yet really last, and it provides enough hold to control wiry grays.
