What is a "roller"?

A roller refers to a cylindrical device commonly used for hairstyling. It typically consists of a hollow cylinder with a Velcro or heat-resistant surface, designed to hold and set sections of hair. Rollers are used to create various hairstyles, such as curls, waves, or volume, by wrapping sections of damp or dry hair around them and securing them in place. They can be heated using a hairdryer or heated rollers to speed up the styling process and help the hair retain its shape. Rollers are versatile tools that allow individuals to achieve different hair textures and styles with ease, making them a popular choice in hairstyling routines.
