Contrary to popular belief, clogged pores, wearing hats, and unhealthy hair shafts are not the cause hair loss. Generally, most people experience hair loss due to a genetic disposition (heredity). Inherited hair loss, known medically as androgenetic alopecia, is the most prevalent type of hair loss in each sex. Commonly referred to as ‘male pattern baldness’ and ‘common female hair loss,’ androgenetic alopecia results from a follicle’s genetically determined sensitivity to hormones, such as dihydrotestosterone (DHT). Such hormones cause sensitive follicles to shrink, over time affecting the hair shaft leading to thinning and ultimately to permanent hair loss. Other factors of hair loss are more temporary, such as stress, illness, nutrient deficiency, and the use of certain drugs.
Generally speaking, male pattern baldness can be expected to occur in 25% of men aged 25-30, 40% of men aged 40, and 50% of men aged 50 or more. The onset of male pattern baldness can be at any time after puberty and, contrary to popular belief, it not infrequently begins in the late teens.
Women generally experience more generalized hair loss. This is also genetic in origin. New techniques allow us to perform transplant surgery on a greater number of women who were not candidates with older technology.
