THE NORMAL cure 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 for and hairloss (push out) a hair shaft. cure Hair is made up of proteins called keratins. Human hair grows in a continuous cyclic pattern of growth and rest known as the "hair 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 for 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 hairloss of the hair occurs only after the next growth cycle cure (anagen) begins and a new hair shaft begins to emerge. On average 50-100 telogen hairs for are shed every day. This hairloss 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, cure radiation, chemotherapy, exposure to chemicals, hormonal and nutritional factors, thyroid disease, generalized or local skin disease, and stress.
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 women as in men. The hair loss in women becomes particularly notable in menopause.Androgens are responsible for hair loss in women by the same for 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 cure of hair in an area if the loss is due to FPHL. If they do they should be evaluated for an underlying pathological (disease) for condition. In women, the process of miniaturization of the hair follicle is more random with some hair being unaffected. Normal thick hairs are mixed with finer, smaller diameter hairs. The end result is a visual decrease in density of hair rather than total loss of hair. The hair growth cycle hairloss is affected as in men. The growth phase (anagen) is shortened resulting in shorter hairs and the resting phase (telogen) is increased resulting in fewer hairs.
