If you have long curly hair or natural black hair, you'll love flexi rods. They're amazing for adding definition to droopy-looking curls or wet-setting hair, and their bouncy/spongy texture makes them a great choice for overnight wear.

The look: 80s-inspired, fluffy curls

Hot, stick-shaped rollers give similar results to flexi rods in a fraction of the time -- great for those of us with pin-straight hair. In less than 45 minutes, they can transform flat, blah hair into a fluffy, sexy mane. Take a cue from Mandy Moore, whose brushed out, Flashdance-fabulous curls are bound to start a trend.

The look: bouncy, slightly mussed waves

Pillow rollers are an update on old-timey, DIY rag curlers, but they're worth the upgrade -- they create more consistent, voluminous waves than rag rollers. They're also not a PITA to wear to bed, whether your hair is dry or damp. If you're a hair-roller novice, these are simple to use, comfy and versatile -- win-win-win.

The look: tangle-free waves and curls

We'll admit that these wacky-looking doodads are a little high-maintenance. First you slip a section of hair in a mesh-like sleeve; then, you wrap it around the cone-shaped roller. The upside is the Velcro roller adheres to the fabric instead of your hair, eliminating any risk of knots. The resulting look is a beachy wave or a princess-y, tapered curl, depending on how long you leave in the curlers.

The look: tight spirals on short, natural hair; beach waves on long hair

Otherwise known as peco rollers, these silicone curlers are pretty genius, especially when you consider they were invented more than a half-century ago. Simply roll up your hair and push on the cup-shaped end of the roller so it flips over, snapping the curler in place. A potential downside: Each roller can hold only a small section of hair, so they work best for women with fine or short hair.
