Although hair loss is mostly seen as a male problem, 60 percent of women over the age of 70 as well as 5 percent of those less than 30 years old experience hair loss, according to WebMD. Androgenetic alopecia is a genetically inherited condition that causes hair loss, and WebMD explains that women who inherit the condition cannot prevent their hair from falling out by limiting their hair's exposure to heat and chemicals. A woman with this type of female-pattern hair loss can experience hair regrowth with Minoxidil 2 percent, which is the only medication the FDA approves for female-pattern hair loss, as of 2014.
Some female hair loss is related to lifestyle factors and stress rather than genetics. For example, excessive use of hair dyes and tight hairstyles like cornrows can cause hair to fall out temporarily, notes WebMD, so limiting use of hair dye and tight hairstyles can prevent hair loss in women. Studies by the American Society of Plastic Surgeons also indicate that women who are divorced or widowed are at a higher risk of stress-related hair loss. Some health problems, including hypothyroidism and iron deficiency, can also lead to hair loss, and treating them can often cause the hair to grow back, notes Prevention.
