Abstract: An apparatus (22) for applying a therapeutic signal (31) to the scalp (32) of a subject (20) includes a first electrode (26) for massaging the scalp (32) and second electrode (30) in contact with the subject (20) and located remote from the first electrode (26). The therapeutic signal (31), passing between the first and second electrodes (26, 30) through the scalp (32), serves to loosen connective tissue and improve blood circulation in the scalp. The apparatus (22) includes digital waveform generators (54) for generating harmonically non-related resultant signals (96). The resultant signals (96) are combined to form the therapeutic signal (31) exhibiting a pseudorandom signal characteristic.

Abstract: A method for applying a therapeutic signal (24) to a body portion (34) of a subject (20) to encourage hair growth utilizes an apparatus (22) that includes a first electrode (28) and a second electrode (32). The first electrode (28) is secured in contact with the skin surface of the subject (20) remote from the body portion (34), and the second electrode (32) is positioned at the body portion (34). The therapeutic signal (24) is provided at a conductive pod (114) of the second electrode (32). The second electrode (32) is manipulated by an operator to apply a circular motion (134) to the body portion (34) underlying the conductive pod (114). The circular motion (134) is repetitively applied as the conductive pod (114) is moved across the body portion (34) to loosen connective tissue at the body portion (34).

Abstract: A massaging electrode is pressed against discrete areas of a subject person's scalp or body and worked from side to side or in a preferred or random massage pattern to thereby move the skin and its underlying layers relative to the underlying area. The electrode is a gold plated phonojack which is encased in silver solder to optimize transmission of electrical current. Electrical current is passed through the electrode and into the subject person's scalp by connecting the electrode to an electrical conductor from an electrical current generating device which generates oscillating voltage to the pad in a low range and at a variation of voltages. The ground contact is hand held by the subject person so that electrical current is directed down through the skin layers during the massaging process.
