An attachment for a hair dryer includes a first end configured to selectively connect to a body of the hair dryer, and a second end spaced from the first end. The second end includes at least one outlet that is an elongate slot. The attachment also includes prongs extending from the second end and configured to engage hair, a body defining a passage for airflow between the first end and the second end, and a connector configured to extend into a central passage defined by the body of the hair dryer and connect the first end of the attachment to the body of the hair dryer. The connector includes a wall extending along an axis and forming an elongate cylinder that corresponds to the shape of the central passage.
