With a curling iron you can easily turn steep curls into a full curly forest. The diameter of the curling iron affects the size of the curls. With a small pair of pliers you make small curls and with coarse tongs, coarse curls. If you want to make it easy for yourself, then you opt for an automatic curling iron. The only thing you do is lay your hair for picking in the curl head and the curling iron does the rest.
