11 Sneaky Reasons Your Hair Is Falling Out

The Most Common Cause of Hair Fall

Although there are a large array of possible triggers for hair fall, the most common cause remains male and female pattern baldness. “Fifty percent of men and women will have some manifestation of hereditary hair fall,” says Mirmirani, “although the pattern of hair fall differs."

This genetically-driven hair fall is not experienced through excessive shedding, but rather a gradual thinning of the hair. Baldness just doesn’t happen overnight. It is also experienced differently in men and women. While men often go completely bald -- specifically on the crown or top of their heads -- women usually experience general thinning on the top of the scalp and rarely experience anything close to total baldness. According to George Cotsarelis, M.D., chairman of the University of Pennsylvania Department of Dermatology, female pattern hair fall “tends to start early if it’s going to be severe.” He says of his female patients, “They [often] think they’ll be bald and [get] very frightened. Most of the time if they’re in their 40s, 50s, 60s, they’re not going to.
Most people lose anywhere from 50 to 100 strands of hair each day, according to the American Academy of Dermatology. On the days when hair is washed, people can lose up to 250 strands, Roberts said. But don’t avoid washing in an attempt to keep the hair, as it will fall out eventually, anyway.

What Other Causes of Hair Fall?

Besides male and female pattern baldness (also called androgenetic alopecia) any number of things can trigger temporary and permanent hair fall. Since most people that experience excessive hair shedding only do so on a temporary basis, Dr. Mirmirani says that sometimes the culprit is never discovered. “There are probably various signals [other than the major ones] that can lead to shedding, but we’re just not in tune with what those are,” she says.
But remember, if you are concerned about excessive hair fall, it’s always best to seek the advice of a medical professional. “When there is an acute loss of hair either in patches or diffusely evaluation by a medical professional is indicated. This way appropriate treatment can be started as early as possible,” says Andrew F. Alexis, M.D., MPH, assistant clinical professor at Columbia University.
