A variation of the afro, a twist-out is a simple way for women with natural hair to keep their hair moisturized and curly. To prepare a twist out, you put two-stranded twists in your hair. Sizes vary, depending on the desired size of curl. For smaller curls, smaller twists are done. For larger curls, larger twists are done. A few hours later, the hair is untwisted to reveal a curly afro.
