Patterned hair loss is the most common cause of hair loss seen in both sexes after puberty, typically presenting progressive thinning, miniaturization, and loss of hair at the affected sites. The hair loss varies in extent and severity and numerous stages exist between the stages of early frontotemporal recession to the stage of residual occipital band.
Male pattern hair loss:
The most common cause of hair loss in men, male-pattern hair loss can begin early. Sometimes, it starts in your late teens or early twenties. Usually, it appears later. By 50 years of age, more than half of white men have a visible sign of male-pattern hair loss like noticeable thinning, a receding hairline, or balding.
Female pattern hair loss:
Is your part widening? Have you noticed that your ponytail is thinner these days? You may have female pattern hair loss (FPHL), a condition that affects millions of women. FPHL is actually the most-common cause of hair loss in women. For most women, FPHL begins in midlife, when a woman is in her 40s, 50s, or 60s.It can begin earlier for some women. FPHL is a progressive condition. This means women tend to continue losing hair. But women do not lose all of their hair, as do some men. Instead, your part often gets wider. Hair near your temples may recede. Without treatment, some women eventually develop widespread thinning. Treatment can prevent hair loss from worsening and help women regrow their hair. Treatment delivers the best results when started at the first sign of hair loss.
