Abstract: A hair styling device for a hairstylist includes a housing configured to be attachable to a styling tool such as a comb, an electronic-based alignment means that determines the angle of orientation of the housing, and a user-actuated operational control for selecting the housing's desired angle of orientation. The electronic-based alignment means provides a human-perceivable indication of the angle of orientation and can be selectively locked to a desired angle. The electronic-based alignment means also selectively provides a human-perceivable indication when the housing is approaching and has arrived at the desired angle.

Abstract: A hair comb body physically associated with hair comb teeth having an electronic-based level that determines the angle of orientation of the associated hair comb teeth and a plurality of lights—visible from at least the front or back face of the body—that indicate the angle of orientation of the associated comb teeth as measured by the electronic-based level, wherein the electronic-based level can be selectively locked to a desired angle, such that the level selectively provides a human-perceivable indication (e.g. audible and/or visual) when the comb teeth are oriented at the desired angle, thus, simplifying the provision of a consistent haircut. A method of cutting hair using the hair comb body is also disclosed.
