PURPOSE: To provide a hair growing brush which can permeate the water-soluble effective element of a hair tonic into a head skin in a short time by using the brush together with the hair tonic.

CONSTITUTION: In the case of a hair growing brush 1, a brush hair part to comb the head hair is made up of metal hair combing pins 32, and an electrode 4 is provided at a handle part that is touched by hand, and at the same time a power source that can feed high frequency pulses between the hair combing pins 32 and the electrode 4 is connected thereto. As a result, a water-soluble effective element contained in a hair tonic is ionized, and at the same time the barrier layer of the head skin is temporarily broken, and efficient permeation into the head skin can be realized.
