Abstract: A hair grooming device includes a brush head surrounded by a rotatable cover member having a lateral opening through which bristles on the brush head are exposable. A handle for the brush head includes a reservoir for a liquid treating agent and communicates through a passage in the brush head with small dispensing holes spaced among the bristles. The cover member is rotatable between a bristle exposed position in which the bristles are exposed through the lateral opening, and a bristle storage position in which the bristles are concealed within the cover member. The cover member has comb teeth thereon adjacent the lateral opening, and seals are provided between the brush head and cover member to prevent leakage of treating agent from the bristles in the bristle storage position of the cover member.
