Ask my hairstylist: my hair is incredibly fine. Volume is scarce; oil is not. I stockpile dry shampoos, dry texturizers, round brushes, and root boosters as if my life depends on it. (To be fair, my hair kind of does—without ‘em it would be flat and greasy). But the key to giving my hair even a little lift is using the best shampoos and conditioners for fine hair. I try to switch it up every wash (there are so many products to test!!), but there are a few tried-and-true options I’ll always go back to when I want a guaranteed good hair day.
