A high-frequency electrotherapy apparatus capable of controlling a variety of output, frequency, and pulse shape is disclosed. The high-frequency electrotherapy apparatus comprises a main body having a switching controller controlling through a digital signal processor (DSP) and a display controller controlling through a microcontroller, and an infrared lamp for the optimum hair-growth effect. High-frequency current is transmitted through a human body using a treatment electrode contacted with a scalp and a counter electrode pad for coupling with the treatment electrode. In the high-frequency electrotherapy apparatus according to the present invention, all the conditions such as the output, frequency, and pulse shape are configured to accomplish the optimum effect for growth of hair. Also, dangerous factors for the human body are removed using a feedback circuit and a grounded frame of the main body, thereby prevent burning or electric shock. Moreover, infiltration depth of the high-frequency is minimized to approximately 2mm, so that diathermy can be achieved without inducing any side effect of the electrical therapy.
