The invention discloses a constant rotation strong-magnetic comb. The constant rotation strong-magnetic comb comprises a comb frame (1) and comb teeth blocks (2), wherein the comb teeth blocks (2) are detachably connected to the comb frame (1), and a rotation strong-magnetic device is arranged on the back of the comb frame (1). According to the constant rotation strong-magnetic comb, through the combined use of an arc-shaped magnet and a direct-current motor, the comb teeth can vibrate, meanwhile, the rotating magnet can generate a magnetic field, so that a constant gyromagnetic function is provided, and the effects of promoting the head blood circulation and the human cell microcirculation are achieved; the rubber soft comb-plate comb teeth have the effect of regulating the acting force, so that the head feels comfortable. The constant rotation strong-magnetic comb is particularly suitable for combing the hair easily having the entanglement and knotting phenomenon, so that the pain and hair breakage caused by pulling can be reduced, the combing injuries are avoided, and the generation of static electricity is prevented.
