Rollers
Cylinders that damp hair is wound around and dried on to set curls, waves or volume.
Also: curlers, roller set
Rollers, or curlers, are tubes that sections of damp hair are wound around and left on until the hair dries, under a hood dryer or overnight. When they are taken out, the hair keeps the curve. Large rollers give volume and smooth waves; small ones give tight curls. The roller set was the weekly salon ritual of the mid-20th century behind the bouffant and the beehive. Heated rollers set dry hair in minutes.
