There is no evidence to suggest that wearing a hat can cause hair loss
, though many people share your concern. Most of us shed 50 to 100 hairs every day, without even noticing. People who wear a hat or a baseball cap on a regular basis will probably notice the hair that has accumulated, giving the illusion of hair loss. While wearing a hat may have nothing to do with your hair loss of the permanent kind, it can prevent proper amount of air circulation to your scalp, and cause sweat clogging up pores (which potentially leads to slower hair growth). That said, it is good idea to see a doctor
about this. In addition to heredity, poor nutrition, and the effect of some medications, there are several causes of hair loss that relate to some medical conditions, such as an autoimmune disease (diabetes or lupus), certain infections, and hormonal problems (hyper or hypothyroidism, or over production of testosterone). Since hair loss may be an early sign of a disease, it is important to see a primary care doctor
to find the cause so that it can be treated.
