A research study at a university in Norfolk, Virginia found that 84 percent of men who experience hair loss are preoccupied with the loss. They described feelings of helplessness, vulnerability, and jealousy in men with full, healthy hair. Men who started hair loss in their early twenties were more likely to have problems with low self-esteem.
The male pattern hair loss is due to a hormone imbalance. The medical term for male baldness is androgenetic alopecia. This term will help you understand the factors that play a role in excessive male pattern baldness. Androgen refers to one of the many hormones that control the appearance and development of male characteristics. One example is testosterone. Genetic refers to inheritance, ie the inheritance of genes either from the mother or from the father. Alopecia simply means hair loss. So it could be said that male pattern baldness occurs due to male hormones that are influenced by genetic inheritance.
DHT (testosterone and 5 - alpha reductase) is a naturally occurring hormone that helps with sexual development. Genetic switches cause changes in the hair follicles in certain men after puberty, namely at androgen-specific receptor sites on the follicles that regulate healthy hair growth . As DHT levels increase as men age, binding to the follicular receptor sites increases. This leads to an imbalance in the biological processes of the more sensitive hair follicles. Slowly, the follicles begin to break down as DHT builds up in the area, making the hair thinner and shorter again, and eventually becoming so thin and short that it is no longer visible.
The Hamilton-Norwood scheme divides androgenetic hair loss in men into different stages, which are assigned to seven levels. This schematic course classification was developed in 1951 by James Hamilton. O'Tar Norwood modified and expanded it in 1975.
Men lose their hair in different ways depending on their genetic makeup. In male pattern baldness , a retraction at the temples, a loss on the top of the head and extensive thinning of the hair can usually be observed. These patterns are identified on what is known as the Norwood Scale , which classifies different types of hair loss.
