I'm a guy with long hair that, depending on my luck, can either look like "early-90s Eddie Vedder" or more like "Hagrid got into a fight with the Whomping Willow and lost" (hi Harry Potter nerds). A satin pillowcase like this one helps keep those latter days to a minimum.

The slippery material doesn't create as much friction when you're tossing in your sleep, so you won't wake up with a giant, tangled frizz ball on your head. It also reduces breakage by not robbing your hair of moisture, which we curly-headed folks need in particular.

The pillowcase comes in a couple dozen colors and patterns, each of which goes for about $9–$11 on Amazon.
