For three-fourths of the male population in the world, hair loss is common. The genetic disposition in men means that after the age of 35 if you haven’t lost a goodly portion of hair you may still lose your hair later in life.
Androgenetic alopecia also known as male-pattern baldness means an inherited gene that is sensitive to dihydrotestosterone. This is a by-product of testosterone. Testosterone is a hormone is secreted primarily from the male reproductive organs. Currently more research has proven that genetic hair loss is attributed from both parents. Past research suggested male-pattern baldness was exclusive inherited from the mother’s side of the family. Now scientists believe both parents contribute to the hair loss factors.
From receding hairlines to progressive apex balding is treatable in some forms. However, for many men, it is an inevitable fact of life. When typical hair loss happens to men, it begins in the temple area, the anterior hairline then sheds backwards, creating the distinct receding hairline. This bitemporal recession of hair will likely continue until baldness matches other affected areas in the scalp.
When apex hair loss happens to many men they are unaware of it until their trip to the barber shop and it is brought to their attention with a mirror displaying the open area on the apex or crown of the scalp. If the average male hasn’t noticed summertime sunburns on the top of the head before the trip to the barber, they are likely in denial. This progressive hair loss happens in a circular pattern around the crown of the scalp and sometimes stalls when it reaches the base of the hairline; leaving a ring of thick, unaffected hair.read post here!
Over time hair loss is inevitable. It will thin over time, likely in the area of the mid-frontal scalp and at the crown. Scientifically, we know now that hair follicles are affected by typical hair loss. When one area begins in males, each hair follicle sequentially will go, leaving a symmetrical pattern. The bitemporal recession will expand from crown to the read of the scalp. The same happens with the receding hairline.
Although hair loss is not isolated on just the scalp, that men sometimes lose hair elsewhere on their bodies, it is the scalp hair loss that scientists are interested in researching. Since scalp hair is different than other body hair, the follicular units produce more than once strand of hair at a time. Interestingly is the presence of a primary hair that shows up shortly after birth in men. From that primary source follicle, secondary branching hairs develop. This begins at the ages of 2-3. These developing secondary hairs are fine and downy. As males age, the hair begins to thicken.see post at http://www.businessinsider.com/most-common-causes-of-mens-hair-loss-2016-3
At the time, androgenetic alopecia begins the follicular units change. The secondary hairs modify and the follicle produces a terminal hair instead of branching units. As the secondary hairs fall out, there are no replacements. The remaining fiber-forming follicle cannot support hair growth and baldness replaces once hair-rich scalp areas.
