Pros: Easily portable and quick to heat up, a curling iron is ideal for spot curls and shorter hair. It will also give you plenty of control over the tightness and shape of your curls.
Cons: Curling an entire head of hair can be time-consuming. The direct heat of a curling iron can damage already dry, stressed hair.
Tip: Protect your hair from heat with a protective styling spray (try TRESemme Instant Heat Tamer Spray).
Pros: A set of hot rollers hair is a great tool for creating a full head of waves or curls, and for hair that is particularly long or thick. Curls set with hot rollers tend to last longer than ones created by other heat methods.
Cons: Hot rollers take longer to heat up and set than a curling iron, but once they're in you'll have your hands free to do other things.
Tip: Freshly washed hair may be a bit too "slippery" for hot rollers. Shampoo the day before or use a texturizing product like Redken Curl Force 17 Texturizing Spray Gel before you style.
Pros: Since they're usable on both damp and dry hair, velcro rollers can be inserted as the final step in your hair-drying routine and set with a quick blast of heat. They tend to create softer curls than other methods and are ideal for creating volume.
Cons: Velcro rollers must be removed carefully from the hair to prevent tangling or breakage
Tip: Give staying power to your curls by spraying each section with a hair spray like Nexxus Comb Thru before wrapping it around the roller.
