A fit for anyone who wants curls or waves without heat damage — including textured and natural hair that's more heat-sensitive — and who doesn't mind that heatless styling takes longer than a curling iron, often several hours or overnight. The pin-free, bendable design also makes them comfortable enough to actually sleep in, which is the main use case Annie markets them for.

These solve a specific problem: wanting curls or waves without adding heat styling to the routine. The foam rod curls hair through wrapping and tension alone, and because there's nothing rigid or pin-based, they're comfortable enough to leave in overnight, which is when they work best.

Apply to damp hair, ideally with a little styling product, for the most defined results — wet or dry hair also works. Wind a section of hair down the length of the rod for a spiral curl, or wrap it around the middle for a looser wave, then bend the foam ends to lock it in place. Leave in for several hours, or overnight for a fuller set, then unwind and style as desired.

Pros

• No heat, so no risk of heat damage even with regular use
• No pins or clips digging in, which makes overnight wear realistic
• Simple to use on wet, damp, or dry hair with no real learning curve

Cons

• Setting takes much longer than a curling iron — often several hours, or overnight for a full set on damp hair
• Using them on fully dry hair with no styling product tends to give looser, less defined results
• Only 3 rollers per pack, so a full head of curls means buying multiples
