{Multi-Wavelength Laser Irradiator For Treating Alopecia for Alopecia Treatment}

The present invention relates to a laser irradiator, and more particularly, to a multi-wavelength laser irradiator capable of treating alopecia by combining laser beams having different output wavelengths.

Hair hairs or hair follicles are grown through three stages of growth, regeneration, and rest period. Adults have about 100,000 hairs and it is normal for 80 hairs to be lost per day. When it is called alopecia (毛毛 症).

Alopecia is a disease in which the hair that normally grows is lost by any cause. The male hormone is converted into dihydrotestosterone (DHT) by the catalytic action of the 5α reducing element and then binds to the androgen receptor It is known that it damages hair follicles and damages blood vessels and causes hair loss. The causes of hair loss include genetic factors, imbalance of hormone secretion (e.g., androgen excess), mental stress, environmental pollution, disorders of blood circulation in the scalp, malnutrition, diseases (e.g., thyroid disease), autoimmune disorders, Antithyroid drugs, oral contraceptives, and hair-changing habits.

The treatment of alopecia such as alopecia areata (hair loss on both sides of the head and both sides of the head begins to expand, gradually becoming thin and weak hair, but eventually disappearing) There is a surgical method and a drug treatment method in which the hair follicles are removed from the living hair of the side hair and transplanted to the hair loss site. The currently marketed hair or hair products have been developed for the purpose of improving blood circulation and supplying nourishment to the hair follicles. However, these are not all medicines and have not been proven effective as quasi drugs such as cosmetics.

In addition, there are only two medicines approved by the public agency, such as the US Food and Drug Administration (FDA), such as minoxidil and propecia, and there is still no satisfactory level of treatment for alopecia patients.

Meanwhile, research on the treatment of alopecia using laser has been going on for a long time. Biological stimulation effect by low power laser irradiation has attracted much interest since the pioneering research of Professor Mester of Budapest University of Hungary in the early 1970s, Much research has been done on the medical use of low power lasers. These studies have shown that low-power lasers are effective in wound healing and pain relief, and a low-power laser has been shown to increase blood flow at the site of irradiation. The biological effect of the low power laser is described, for example, in " T. I. Karu, 'Low-power laser therapy', In: Biomedical Photonics Handbook, Ch. 48 (2003), 48-1 to 48-25, " M. Schaffer, H. Bonel, R. Sroka, P.M. Schaffer, M. Bosch, M. Reiser and E.
