Hair curlers and hair wavers are also popular hair styling tools. These hair tools add flair to any hairstyle by changing the layout of the hair. Adding curls or waves throughout the hair to the tips can create totally different hairstyles. These tools are easy to use and a lot of women feel comfortable using them to change their hairstyle up. Hair setters also perform the same function as hair curlers but they are meant to be set on and cannot be varied as much. They come in different sizes for producing different curls but cannot be adjusted as much as hair curlers.
