There are many types of rollers, both non-heated and heated. They all vary in length and width -- a wide diameter gives a full, smooth curl, while a thin roller gives a tight, spiral-type curl. When using non-heated rollers, set your hair before taking a shower: The steam will help set the curls for a long lasting style. And never wind rollers too tightly, or you could end up with hair loss.
Magnetic rollers add smooth curl and volume. Because they are used to set wet hair, they offer long lasting curl.
Velcro rollers provide soft curl and full body, and can be used on either damp or dry hair. These are good choices for short or fine hair and hair that breaks easily, since they don't need to be clipped in place. However, if your hair is long or thick, you might need to use clips to keep Velcro rollers in place.
Foam rollers give curl to fragile hair and are best used when your hair is dry; they're even soft enough to sleep on.
Snap-on rollers and brush rollers hold hair securely, but they can damage your hair and are therefore not usually recommended.
Plastic mesh rollers are best used on wet hair. They help hair dry quickly and create smooth curls.
Flexi-rods and hair twirlers are long, flexible cushioned rods designed to create spiral curls without the use of pins or clips.
Hot rollers and steam rollers, available in a variety of diameters, are used on dry hair to create long lasting curl and minimize frizz. Both types are less damaging to hair than irons. Hot rollers are faster to use—you have to wait for steam rollers to dry before taking them out. However, steam rollers are the gentlest way to get soft, full curls. When using either type of heated rollers, carefully wrap small sections of hair, making sure the ends are tucked in.
