Embodiments of the present invention relate to a hair roller which can be separated into a pair of half-cylindrical roller pieces, pairs of half-cylindrical roller pieces, and a method of storing half-cylindrical roller pieces by nesting the half-cylindrical roller pieces. The hair roller of the invention includes a whole cylindrical body separable along a vertical axis into half-cylindrical roller pieces which include a plurality of mating devices configured to selectably couple the half-cylindrical roller pieces to form the whole cylindrical body, wherein the half-cylindrical roller pieces are capable of being nested. The pair of half-cylindrical roller pieces of the invention are identical in shape, which include a plurality of tabs and orifices, where the tabs have protuberances which protrude into a corresponding orifice when the lateral edges of the pair of roller pieces are aligned.

A heatless animal-styled hair curler provides an adjustable-length headband for fitting different-sized heads, two adjacent curling rods for wrapping hair, and an animal-themed exterior surface which mimics the look of an animal when worn in order to encourage use by a child or young adult. The adjustable-length headband is formed from a thin, flat piece of elastic material which comfortably rests flush and secure on top of a user's head, and which is adjustable via a buttonhole elastic adjustment mechanism accessible from an opening in an underside portion of the exterior surface. Cylindrical curling rods made from a polyester fiber fill material are attached with each end of the headband to provide a curling area where a user can wrap their hair to create curls. The animal-themed surface includes patterns and shapes extending from the headband, such as ears or eyes, to mimic the look of an animal.
