Abstract This invention pertains to a curl keeping hair cap made of a substantially circular sheet of nonabsorbent air permeable material for permitting air circulation with a casing secured along the circular edge of the sheet and a drawstring having an elastic portion extending through the casing to permit adjustment of the hair cap to fit the contour of the face and neck of the wearer by gathering along the casing. The drawstring has tie ends which can be tied to each other to maintain the elastic portion of the drawstring in a stretched condition. The hair cap may be made of a single piece of nylon. A method of maintaining a hair permanent comprises applying permanent curl solution to hair, rinsing the solution from the hair, and enclosing the hair in a substantially circular curl keeping hair cap of nonabsorbent air permeable material with a drawstring having an elastic portion to gather the cap and fit the contour of the face and neck.
