Hair has many useful biologic functions, including protectionfrom the elements and dispersion of sweat-gland products (e.g.,pheromones). It also has psychosocial importance in our society,and patients with hair loss (alopecia) (Table 1) or excessivehair growth often suffer tremendously. Not surprisingly, thedemand for drugs that alter hair growth and appearance has ledto a multibillion-dollar industry, yet few drugs that are effectivefor these purposes are available. However, recent progress inour understanding of the biology and pathology of hair folliclesshould lead to more effective therapies for disorders of hairgrowth.
