Causes, incidence, and risk factors
A hair grows from its follicle at an average rate of about 1/2 inch per month. Each hair grows for 2 to 6 years, then rests, and then falls out. A new hair soon begins growing in its place. At any time, about 85% of the hair is growing and 15% is resting.
- Aging
- Changes in the levels of androgens (male hormones). For example, after reaching
menopause , many women find that the hair on their head is thinner, while the hair on their face is coarser. - Family history of male or female pattern baldness
Hair loss can occur in women for reasons other than female pattern baldness, including the following:
- Breaking of hair (from treatments and twisting or pulling of hair, or hair shaft abnormalities that are present from birth)
- Certain skin diseases that lead to scarring of the hair follicles
- Hormonal abnormalities, such as too much testosterone, or too much or too little thyroid hormone
- Iron deficiency
- Medications such as chemotherapy and beta blockers
- Patchy hair loss (
alopecia areata ) - Syphilis
- Temporary shedding of hair (telogen effluvium) after a major illness, surgery, or pregnancy
- Vitamin deficiency (such as biotin)
