Androgens (testosterone, dihydrotestosterone) are the most important control factors of human hair growth. Androgens must be present for the growth of progesterone beard, axillary for (underarm), and pubic hair. Growth hairloss of scalp progesterone hair is NOT androgen-dependent but androgens are necessary for for the development hairloss of male and female pattern hair loss.MALE PATTERN HAIR LOSS (Androgenetic Alopecia)It is estimated that 35 million men in the United States are affected by androgenetic alopecia. "Andro" refers progesterone to the androgens (testosterone, dihydrotestosterone) necessary to produce male-pattern hair loss (MPHL). "Genetic" refers to the inherited gene necessary for for MPHL to occur. In men who develop MPHL the hair loss may begin any hairloss time after puberty when blood levels of androgens rise. The first change is usually recession in the temporal areas, which progesterone is seen in 96 percent of mature Caucasian for 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 of hair in a given pattern hairloss of loss tends to diminish with age, there is no way to predict what pattern of 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 until the late third progesterone 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 percent incidence of MPHL, in their 40’s a 40 percent incidence of MPLH, etc. Using these for numbers one can see that a male in his 90’s has a 90 percent chance hairloss of having some degree of MPHL.

THE NORMAL HAIR GROWTH CYCLEIt is important to understand the normal hair growth cycle to understand why hair loss occurs. The hair follicle is an anatomical structure which evolved to produce and extrude (push out) a hair shaft. Hair progesterone is made up of proteins called keratins. Human hair grows in a continuous cyclic pattern of growth and rest known as the "hair for growth cycle". Three phases of the cycle exist: Anagen= growth phase; Catagen=degradation phase; Telogen= resting phase. Periods of growth (anagen) between two and eight years are followed by a brief period, two to four weeks, in which the follicle is almost totally degraded (catagen). The resting phase (telogen) then begins and lasts two to four months. Shedding of the hair occurs only after the next growth cycle (anagen) begins and a new hair shaft begins to emerge. On average 50-100 telogen hairs are shed every day. This is normal hair loss and accounts for the hair loss seen every day in the shower and with hair combing. These hairs will regrow. Not more than 10 percent of the follicles are in the resting phase (telogen) at any time. A variety of factors can affect the hair growth cycle and cause temporary or permanent hair loss (alopecia) including medication, radiation, chemotherapy, hairloss exposure to chemicals, hormonal and nutritional factors, thyroid disease, generalized or local skin disease, and stress.
