Yup, working long hours can lead to the development of alopecia.
The study comes from the Sungkyunkwan University School of Medicine and Kangbuk Samsung Hospital's Department of Occupational and Environmental Medicine in Korea. Researchers conducted the four-year-long study to "explore the relationship between long working hours and the development of alopecia among Korean male workers."
Though hair loss has a lot of causes—genetics, stress, infection, hormonal imbalance, blood circulation disorders, nutritional imbalance, and drug use—workers who clocked in 40 to 52 hours a week were more at risk for baldness. And it all points to job-related stress.
We're not at all against baldness (a lot of men can pull it off!), but maybe skip overtime for your hair's sake.
Korea, as it seems, is really into studying hair loss. In fact, scientists over there have been trying to develop a cure for baldness.
