A hair roller or hair curler is a small tube that is rolled into a person’s hair in order to curl it making a new hairstyle.The diameter of a roller varies from approximately 0.8 inches (20 mm) to 1.5 inches (38 mm). The hair is heated and the rollers strain and break the hydrogen bonds[citation needed] of each hair’s cortex which causes the hair to curl.
