What to look for
Cordless or corded
Cordless tools go in a bag and work anywhere; check how they charge and how long a charge lasts before you buy.
Heat you can control
Adjustable heat settings let you use less heat on fine or treated hair and more on thick hair.
Automatic curlers
An auto-rotating curler wraps the hair for you, which is faster and easier on the wrist than a wand.
