A grooming device includes hair collectors and a scraper. The scraper uncovers the hair collectors when the device is pressed down for use, and scrapes the hair collectors to eject hair collected when the device is released. Ejection of collected hair can also be controlled manually. A collection chamber may be provided, and multiple combs may be mounted on a rotatable dowel that recede within the rotatable barrel, or with sliding plates around and offset from the dowel as the dowel is rotated. A door or window on a surface of the collection chamber can be opened to empty the chamber of collected hair.
