Usually, hair loss isn’t something you need to be concerned about. However, in some cases it can be a sign of something more serious. The usual and most likely causes of hair loss are illness, stress, weight loss and iron deficiency. Although this hair loss can be upsetting, it’s not permanent and can sometimes be treated. Some more serious cases can be caused by some cancers, but this is uncommon.
