## Abstract

The current invention includes a device and method for the promotion and stimulation of hair growth using one or more light sources such as a diode laser, each light source operating at a low wattage, collectively less than about 1000 mw, with the power level typically being in the region of 500 mw, in the infrared range at wavelengths in a range from about 2500 nm to about 10,000 nm. A diode laser operating in this range will have a greater dispersion rate than heretofore, thus requiring fewer diodes to cover the same area of scalp with less power required per diode laser.

## Claims

### Claim 1

A method for promoting the hair growth on the head of a patient, the method comprising the following steps:
arranging one or more light sources along one or more circumferential bands about the scalp of the patient and at a distance between the band and the scalp, each light source emitting a wavelength of coherent light at a specified power level, the wavelength in a range from about 2500 nm to about 10,000 nm;
moving the one or more bands over the scalp according to a periodic cycle, the movement accomplished within a length of time; and
wherein a selected portion of the scalp is traversed by the dispersion pattern of the light sources at least once during the periodic cycle.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the specified power level of each light source is between 0 mw and 100 mw.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the total collective power level of the device is less than about 1000 mw.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the specified wavelength of each light source is about 3400 nm.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the light source is a diode laser.

### Claim 6

A device for stimulating hair follicles of a scalp of person through exposure to coherent light, the device comprising:
a pair of earpieces, each earpiece positioned over the ear, the pair supported by a support means extending between the earpieces in a stationary position with relationship to the shoulders and neck of the person;
a band extending between the earpieces circumferentially around the head of the person for reciprocal motion between the nape of the neck and the forehead, the band positioned a distance away from and over the scalp, the band having one or more light sources adapted to emit a beam of coherent light in a direction of the scalp, each light source emitting coherent light having a wavelength in a range of from about 2500 nm to about 10,000 nm;
a means for stabilizing the band for angular movement over the scalp; and
a means for controlling the angular movement of the band and the actuation of the light sources.

### Claim 7 (depends on 6)

The device according to claim 6, wherein the light source is a diode.

### Claim 8 (depends on 6)

The device according to claim 6, wherein the specified power level of each light source is between 0 mw and 100 mw.

### Claim 9 (depends on 6)

The device according to claim 6, wherein the total collective power level of the device is less than about 1000 mw.

### Claim 10 (depends on 6)

The device according to claim 6, wherein the specified wavelength of each light source is about 3510 nm.

### Claim 11 (depends on 6)

The device according to claim 6, wherein the rotational movement is accomplished according to a cyclical sequence.
