Understanding Hair Loss
Androgenic alopecia is the scientific name for the genetic predisposition in both men and women for pattern baldness. Genetic hair loss in men is often referred to as Male Pattern Baldness (MPB) and is the cause of thinning hair in over 95% of patients who seek treatment. MPB occurs in predictable stages, and is relentlessly progressive. Usually the earlier in life hair loss begins the more advanced the pattern will ultimately become.
In MPB, the hairs on the top of the scalp have a genetic sensitivity to the male hormone testosterone (DHT). The hairs on the sides and back of the scalp do not possess this sensitivity to DHT and therefore are not affected. For this reason hairs removed from the sides and the back (Donor Hair) will maintain their genetic predisposition when transplanted and continue to grow when moved to the top of the scalp where hair loss has occurred.
Hair loss in females is less predictable. The hair loss tends to be more diffuse creating a more generalized thinning effect throughout the entire scalp. Fewer medical and surgical options are available for these patients.
Causes for Hair Loss
As stated earlier, both men and women develop this type of hair loss, which is the most common cause of hair loss worldwide. In men, it’s called male pattern hair loss. Women get female pattern hair loss. Regardless of whether it develops in a man or women, the medical term is androgenic alopecia or simply genetic hair loss.
No matter which term you use, it means that you’ve inherited genes that cause your hair follicles (what each hair grows out of) to shrink and eventually stop growing hair. Shrinking can begin as early as your teens, but it usually starts later in life.
In women, the first noticeable sign of hereditary hair loss is usually overall thinning or a widening part.
When a man has hereditary hair loss, the first sign is often a receding hairline or bald spot at the top of his head.
Is Age a Factor in Hair Loss?
Although aging is not a cause for hair hair loss, with aging most people notice some hair loss because hair grows slower. At some point, hair follicles stop growing hair, which causes the hair on our scalp to thin. Hair also starts to lose its color. A woman’s hairline may naturally starts to recede.
