In the United States it is estimated that xenical 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 for particularly notable in menopause.Androgens hairloss are responsible for hair loss in women by xenical the same 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 or adrenal glands. Women rarely experience total loss of hair in an area if for 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 hairloss of the hair follicle is more random with some xenical hair being unaffected. Normal for thick hairs are mixed with finer, hairloss smaller diameter hairs. The end result is a visual decrease in density of hair rather than total loss of hair. The hair growth cycle is affected as in men. xenical The growth phase (anagen) is shortened resulting in shorter hairs and the resting phase (telogen) is increased resulting for in fewer hairs.
Hamilton first noted that androgens (testosterone, dihydrotestosterone) are necessary for the development of MPHL. The amount of androgens present does not need to be greater than normal for MPHL to occur. If androgens are present in normal amounts and the gene for hair loss is present, male pattern hair loss will occur. Axillary (under arm) and hairloss pubic hair are dependent on testosterone for growth. Beard growth and male pattern hair loss are dependent on dihydrotestosterone (DHT). Testosterone is converted to DHT by the enzyme, 5a -reductase. Finasteride xenical (Propecia) acts by blocking this enzyme and decreasing the amount of DHT. Receptors exist on cells that bind androgens. These receptors have the greatest for affinity for DHT followed hairloss by testosterone, estrogen, and progesterone. After binding to the receptor, DHT goes into the cell and interacts with the nucleus of the cell altering the production of protein by the DNA in the nucleus of the cell. Ultimately growth of the hair follicle ceases.
