Long working hours increase development of hair loss a new study suggest.
The researchers say stress is the most likely culprit, triggering damage to follicles and causing the hair to enter the ‘catagen’ phase.
The researchers, from Sungkyunkwan University School of Medicine in Seoul, South Korea, looked at 13,391 men aged between 20 and 59 from 2013 to 2017.
They were split into three groups: ‘normal’, who worked a 40-hour week, ‘long’ as up to 52 hours, and ‘much longer’ as any time above that.
Author Kyung-Hun Son said: ‘The results of this study demonstrate that long working hours is significantly associated with the increased development of alopecia in male workers.
Limitation of working hours in order to prevent alopecia development may be more necessary from younger workers, such as those in the 20s and 30s, at which hair loss symptoms start to appear.
‘Preventive interventions to promote appropriate and reasonable working hours are required in our society.
The research was published in the Annals of Occupational and Environmental Medicine journal.
