A hair styling band includes a hair band body adapted to be worn on a head of a user to keep the hair of the user in place. The hair styling band further includes a C-shaped support member having first and second ends defining an opening. The first and second ends of the support member are pivotally combined to two legs of the hair band body so that the support member can be pivoted relative to the hair band body. When the hair band body is worn on the head of the user, the user can, according to the need, move the support member to a proper position above the head so that an upper layer hair of the user can cover on the support member to create a hairstyle of increased hair volume, achieving the effects of styling the hair and adjusting the hairstyle height.
