Androgens (testosterone, dihydrotestosterone) are the most important control factors of human hair growth. Androgens must be present for the growth of beard, axillary (underarm), and pubic hair. Growth of scalp hair is NOT androgen-dependent but androgens are necessary for the development women of male and female pattern hair loss.MALE PATTERN and HAIR LOSS (Androgenetic Alopecia)It is estimated that 35 million men in the United States are affected by androgenetic alopecia. "Andro" refers hairloss to the androgens women (testosterone, dihydrotestosterone) necessary to produce male-pattern hair loss (MPHL). "Genetic" refers to the inherited gene necessary for MPHL to occur. In men who develop MPHL the hair loss may begin any time after puberty when blood levels of androgens rise. The first change is usually recession in the temporal areas, which is seen in 96 percent of mature Caucasian males, including those men not destined to progress to further hair loss. Hamilton and later Norwood have classified the patterns of MPHL (See Norwood-Hamilton Scale). Although the density and of hair in a given pattern of loss tends to diminish with age, there is no hairloss way to predict what pattern of women hair loss a young man with early MPHL will eventually assume. In general, those who begin losing hair in the second decade are those in whom the hair loss will be the most severe. In some men, initial male-pattern hair loss may be delayed and until the late third to fourth decade. It is generally recognized that men in their 20’s have a 20 percent incidence of MPHL, in their 30’s a 30 hairloss percent incidence of MPHL, in their 40’s a 40 percent incidence of MPLH, etc. Using these numbers one can see that a male in his 90’s has a 90 percent chance of having some degree women of MPHL.

In the United States it is estimated that 21 million women are affected by FPHL. The incidence in women has been reported to be as low as eight percent and as high as 87 percent. It does appear to be as common in and women as in men. The hair loss in women becomes particularly hairloss notable in menopause.Androgens are responsible women for hair loss in women by the same and mechanisms they cause hair loss in men. Women do produce small amounts of androgens by way of the ovaries and adrenal glands. Also prehormones are produced by the ovaries that are converted to androgens outside of the ovaries hairloss or adrenal glands. Women rarely experience total loss of hair in an area if the loss is due to FPHL. If they do they should be evaluated for an underlying pathological (disease) condition. In women, the process of miniaturization of the hair follicle is more random with some hair being unaffected. Normal women thick hairs are mixed with and finer, smaller diameter hairs. The end result is a visual decrease in density of hair rather than hairloss total loss of hair. The hair growth cycle is affected as in men. The growth phase (anagen) is shortened women resulting in shorter hairs and the resting phase (telogen) is increased resulting in fewer hairs.

Though humans no longer make use of hair for protection, heat retention, and or camouflage, it still remains a very important hairloss and women means by which individuals display and are recognized. Appropriate appearance and grooming are still very important in social organization and the human relationships.The human body contains approximately five million hair follicles while the scalp (prior to any kind of hair loss) contains 100,000 - 150,000 hair follicles. Blondes have the greatest and number of hairloss scalp follicles, followed by brunettes. Humans with red hair have the fewest number of scalp follicles. The normal growth rate of scalp hair is one-fourth to one-half inch per month.
