The average human scalp contains 100,000 hair follicles. Red-haired scalps average about 25 percent fewer hairs and blond-haired heads tend to average about 25 percent more hairs than brown-haired scalps. At puberty, the hairline moves back a little in 96 percent of boys due to the androgen hormone spurt.
The causes of hair loss can be grouped into the following categories:
Male or female pattern baldness
This type of hair loss requires the presence of androgens but the cause is unknown. The extent of hair loss in any man depends greatly on the genes he inherits from the father, mother or both.
Hair loss begins in the temples or at the top of the head. If male pattern hair loss begins in the mid-teens, subsequent hair loss is usually is extensive. Male balding goes in waves. The hair loss may begin in the early 20’s, and then stop, only to start again in a few years.
By the age of 20 to 30 years, 30 percent of men have bald spots. This continues to rise until age 50-60 when 50 percent of men are completely bald.
The rate of hair loss is affected by advancing age, the tendency to bald early due to inherited genes, and an overabundance of the male hormone dihydrotestosterone within the hair follicle.
Although balding men have above average amounts of dihydrotestosterone in their hair follicles, they usually do not have above average circulating testosterone levels.
Female pattern baldness is not as common as a male pattern but is on the rise. It is confined to thinning of the hair predominantly at the top of the head. Complete baldness is rare.
