Description

Scalp stimulation and chemical application device {Apparatus for stimulating hair growth and preventing hair loss}

The present invention relates to a scalp stimulation and chemical application device that can effectively supply copper ions and zinc ions to the scalp.

Hair grows and loses hair through a three-stage cycle of anagen, catagen, and telogen. Adults have about 100,000 hairs, and it is normal for about 80 hairs to fall out per day. If it progresses beyond that, it is called alopecia.

Hair loss can be clinically divided into two types: those in which scars are formed and those in which scars are not formed. Hair loss in which scars are formed does not allow hair regeneration because the hair follicles are destroyed, whereas hair loss in which scars are not formed is a symptom because the hair follicles are maintained. After the area disappears, the hair regrows. Non-scarring alopecia in which scars do not form include hereditary androgenetic alopecia (baldness), alopecia areata, tinea capitis caused by fungal infection, telogen effluvium, hair growth barrier, and hair growth disorders, and cicatricial alopecia in which scars are formed. Examples include hair loss due to lupus, toxic folliculitis, lichen planus pilaris, and hair loss due to burns and trauma. (Hair loss [alopecia] (Seoul National University Hospital medical information, Seoul National University Hospital)

Alopecia is a disease in which normally growing hair falls out due to any cause. Male hormones are converted into dihydrotestosterone (DHT) by the catalytic action of 5α-reductase, and then bind to the androgen receptor, causing hair papillae and hair follicles to grow. It is known to cause hair loss by reducing the function of hair follicles and damaging blood vessels.

Treatment of alopecia, for example, androgenetic alopecia (a condition in which hair loss begins in the frontal and parietal regions on both sides of the head and gradually expands, causing thin and weak hair to appear at first and eventually disappear) is for patients whose hair follicles have completely disappeared. There are surgical methods and drug treatment methods that involve removing skin with living hair follicles from the back or side of the head and transplanting them to the hair loss area.

Hair growth agents or hair growth agents currently on the market were developed for the purpose of improving blood circulation in the skin and supplying nutrition to the hair roots, but these are not drugs and are quasi-drugs such as cosmetics, so their effectiveness has not been proven. In addition, there are only two drug treatments officially recognized by public institutions such as the U.S. Food and Drug Administration (FDA), Minoxidil and Propecia, and the reality is that there is still no treatment method that satisfies alopecia patients.
