Final answer:
Barrel curls are large diameter pin curls that do not have the same amount of tension as rollers.
Step-by-step explanation:
Large diameter pin curls that are similar to a roller but do not have the same amount of tension are called barrel curls. Barrel curls are created by wrapping a large section of hair around a curling iron or other styling tool, resulting in a loose, voluminous curl. Unlike roller curls, barrel curls are not achieved by using rollers with tension.
