A hair brush for use with a person's head of hair is described in this disclosure. The hair brush illustratively includes a handle and a brush head with bristles that extend out from a hair-shaping guide.

A method, system, and device for measuring and evaluating hair loss over time is disclosed. A instrumented comb device includes a power source, a controller, and associated sensors. The controller receives signals from the sensors, including a contact sensor to detect contact with a scalp and obtain a hair count, and a magnetic compass to determine location on the scalp. The controller includes one or more processors that acquire and record the detected contact information and determined location information as the comb device is stroked over a scalp, and measure hair density based on the contact information and location information. The instrumented comb can communicate with a remote information system or a mobile device for auxiliary processing and display. Machine learning of the remote information system allows for recognizing hair density or prediction of future trends in hair density over time using data recorded by the sensors.

An instrumented comb, including bristles protruding from the handle, the bristles spaced apart from each other such that a first set of two or more bristles are spaced by a first distance, a second set of two or more bristles are spaced by a second distance, and a third set of two or more bristles are spaced by a third distance, wherein the third distance is greater than the second distance and the second distance is greater than the first distance. The comb includes a controller receiving signals from: a contact sensor to detect contact with a scalp, and a magnetic compass to determine location on the scalp. The comb uses the signals to record the detected contact information and determined location information as the comb undergoes a brushing gesture over a scalp, measure hair density based on the contact information and location information, and output the measured hair density.

A power hairbrush which oscillates in operation with a frequency in the range of 55 Hz-120 Hz and an amplitude in the range of 8-20, with a brushhead adapted to remove sebum and other material from the scalp and hair of a user, the brushhead including a plurality of lines or rows of filament tufts, wherein each filament in the filament tufts at its distal end is split into several portions. The brushhead further includes a plurality of lines of solid tuft members positioned adjacent to the lines of filament tufts. The filament tufts are approximately 1-3 mm taller than the solid tuft members.

The present disclosure discloses a water absorption comb, which includes a water absorption layer; and an evaporation component matched with the water absorption layer and used for accelerating the evaporation of water in the water absorption layer. By adopting the design above, the water in the water absorption layer is quickly evaporated through the evaporation component, so that the comb can be continuously used and plays a role in absorbing water.

A hair brush adapted to impart both a straightening effect and a curling effect on a length of hair includes first and second members. The first member includes a first handle and a first brush head having an inner row of centrally disposed primary teeth, an outer row of bristles mounted on each side of the centrally disposed primary teeth, and a thermal conductive element. The thermal conductive element defines an arcuate surface configured for imparting a curl within a lock of hair. The second member includes a second handle, a second brush head having a second head frame defining a longitudinal channel, and an elongate member having a wiper segment disposed on each side of the longitudinal channel, and configured to engage the length of hair to facilitate one of straightening of the length of hair or removing substances from the length of hair.
