Abstract: A plurality of electrodes are mounted within a hood positionable over a subject's hed to form an array of concentric electrically conductive electrode rings. The rings can be applied to an outer surface of an electrically insulating liner insertable within the hood. The array preferably comprises five rings mounted within the hood to subtend a 90° arc on both sides of a central perpendicular axis of the hood. The four upper electrodes each subtend an arc of about 15° and the fifth (lower) electrode subtends an arc of about 6°, with 6° arc gaps between each pair of electrodes on either side of the central perpendicular axis. A voltage pulse signal generator's output signal is connected across the two upper electrode pairs, with alternate electrodes being connected to one of the two output terminals of the voltage pulse generator. A voltage divider applies a reduced voltage signal to the lower electrode.

The rings can be applied to an outer surface of an electrically insulating liner insertable within the hood. The array preferably comprises five rings mounted within the hood to subtend a 90.degree. arc on both sides of a central perpendicular axis of the hood. The four upper electrodes each subtend an arc of about 15.degree. and the fifth (lower) electrode subtends an arc of about 6.degree., with 6.degree. arc gaps between each pair of electrodes on either side of the central perpendicular axis. A voltage pulse signal generator's output signal is connected across the two upper electrode pairs, with alternate electrodes being connected to one of the two output terminals of the voltage pulse generator. A voltage divider applies a reduced voltage signal to the lower electrode.

Abstract: Hair regrowth is promoted by positioning one or more electrodes closely proximate a subject's scalp. A low voltage positive or negative polarity signal having a selected frequency of either 7.86 or 15.72 hertz is applied to the electrode(s) for about twelve minutes. The subject undergoes a hair regrowth treatment cycle spanning a period of about thirty-two weeks during which one or two of the treatments aforesaid are applied per week.
