A hairbrush for styling hair has a brush head releasably connected to a rod rotatably mounted on a handle portion of the hairbrush and having a handle. The brush head has a plurality of spaced apart bristles for insertion between strands of the hair and gripping the strands therebetween. As the rod, and therefore the brush head are rotatable relative the handle, the brush head, with strands of hair gripped thereon, can be rotated as the handle is moved towards the head of a person whose hair is being styled, thus causing the strands of hair to be rolled around brush head, without requiring cumbersome twisting of the handle. A spring facilitates rotation in an opposite second direction and unrolling of the strands of hair off the brush head. A locking pin enables locking and unlocking of the rod and brush head to prevent and enable rotation thereof.
