It’s disconcerting to suddenly notice extra hairs in your hands, your hairbrush or on your pillow. It’s even worse to see visibly thinner hair or even bald spots on top of your head.
People naturally lose around 50-100 hairs per day, but losing hair in greater quantities could be cause for concern. For some, particularly men, hair loss is caused by genetics and is permanent. Many other people, however, experience only temporary hair loss, which can be triggered by a variety of external factors.
