Male pattern hair loss

The majority of men are going to decrease the amount of hair in any way before the head and the top of the head with age. Therefore, it is to be a normal physiological phenomenon, not treated as a disease. However, not only to the part of the frontal or parietal, in some cases eventually spread hair loss on the entire head.

Age that male pattern baldness starts is a vary by person, but appear to men of ordinary 30s too, and sometimes starting with the mid-teens. Male pattern baldness that begins in up to 20 generations may be distinguished as a juvenile alopecia. In addition, women have also been an increasing number of people who develop male pattern baldness in recent years. Male pattern baldness of women in which a wide range becomes thinner in the center of the top of the head, thin becomes how the typical male pattern baldness is different, but the mechanism is the same thing.

In the men with a genetic predisposition, under the influence of elevated androgen after puberty, weakening the hair follicle that wrapped the hair matrix cells that make the hair, the hair gradually thins, such as downy hair (lanugo) hair only will not remain. Than that male hormone levels of the patient is normal, androgen sensitivity of the hair follicle itself is to determine this disease, in particular, and quantitative differences in the 5α- reductase type U in the dermal papilla cells, androgen receptor of the same cell idea that is defined by the quality and quantity of became common. But responsible gene is to not yet been found, not known also factor to convert the terminal hair to vellus hair.

In Japan, young bald there is a tendency to be despised for a long time. In particular, in recent years it has shed actively television commercials wig industry and hair tonic industry, young men often juvenile alopecia cause serious trouble.

Alopecia-related in the prime of life

■ Concept of alopecia-related in the prime of life
By the change that the hard hair of the calvarial ... maegashira part switches to a pubis under the influence of the male hormone, I am called male pattern baldness, the young baldness. Unlike senile hair loss, the feature of the hair follicle is that it does not decrease. The disease is not considered to be the disease that is a physiological change (personality of the skin).

■ Frequency of alopecia-related in the prime of life
There are not the inspected statistics, but it is generally thought medically with around 30%.

■ Etiology, onset mechanism of alopecia-related in the prime of life
In the men with a hereditary factor, the above-mentioned hair follicle makes it a miniature under the androgenic influence that rose after the puberty, and hard hair makes it a pubis. A thought that it was prescribed with quality and the quantity of the androgen receptor of a quantitative difference of the 5α-reductase type II in androgenic sensitivity of hair follicle in itself particularly the hair nipple cell and the cell that I decided the disease than the quantity of male hormone of the patient being normal was commonly used. However, the responsibility gene is not yet found and does not understand the factor transferring hard hair to a pubis.

■ Clinical manifestations of alopecia-related in the prime of life
Expansion of the sum and calvarial Usuge show a lot of becoming it early. The hair follicle becomes a miniature more and more, and pubises increase afterwards. I shorten it more and more for the period of growth, and the hair follicles which do not shift for a period of growth from a resting stage finally increase, and the number of the hairs decreases, too. When senile falling-out hair is piled up, I may suffer from all head hair loss. A light symptom may develop in the women, but onset time is delayed to a man for ten years, and it features the frontal hairline to stay. When I see a similar change to a young woman, I doubt ovarian function imperfection.

■ Treatment policy of alopecia-related in the prime of life
Many cures are devised, but there is not yet the medical therapy that I can be satisfied with.

■ Cure for alopecia-related in the prime of life
[1] Whole body therapy
Antimale hormone drug (Propecia, model 5 α - reductase repressor) internal use was accepted in the United States, but is unauthorized in our country.
[2] Local therapy
I keep a scalp clean and plan bloodstream increase, the supplementation of the root of hair part, hair follicle environment maintenance with a hair growth agent, a hair restorer.
[3] Operative treatment
A hair follicle from the back of the head isolates it and transplants it, and art of hair loss department reefing, the substitution art by the existence stem skin of dialect from the both sides of the head part are performed in plastic surgery mainly.

Hair loss from Androgenetic (Genetic hair loss)

Hair loss from Androgenetic, also known as male pattern hair loss is a major problem that affects men, and are such that up to 50% of men who are made genetically inclined to be affected by the age 50th It is characterized by progressive, patterned hair loss from the scalp, and its prerequisites are a genetic predisposition and sufficient circulating androgens (steroid hormone such as testosterone or androsterone, which promotes male characteristics). According to Sinclair (1998) every white man has inherited predisposition of autosomal, and as such, 96% lose hair to some degree. Sinclair also mentions that white men are four times more likely to develop early hair loss than Black men. Hair loss begins to puberty with an extremely variable rate of progress is not usually on.

The condition is quite common in women and is called female pattern hair loss. In women, "it is characterized by the diffuse reduction in hair density over the crown and frontal scalp with retention of the frontal hairline". Birch and al (2002) mention the fact that in some women the hair loss may affect a small area of the frontal scalp whilst in others the entire scalp is involved. In advanced female pattern hair loss, the hair is very sparse over the top of the scalp bit a rim of hair is retained along the frontal boundary. The vertex (crown or top of the head) balding seen in men becoming rare in women; However, a female pattern of hair loss in men is not uncommon. The dependent androgen nature or the genetic basis of female pattern hair loss have not been clearly established, although a study is carried out by Sinclair and al (2005) showed that androgens play an important role in the development of female pattern hair loss play.
