Hair loss is a common complaint at the office. Most patients would suffer from patterned hair loss or androgenetic alopecia. As the name implies, this is often hereditary. Most patients can be treated simply if they present early enough. This treatment often entails lotions and sometimes medications when needed. Hair loss is a huge chapter in Dermatology, with many causes. Some may be due to deficiencies or internal disease. These cases need to be carefully sifted out from the more common causes. Often we use non-invasive instruments such as dermatoscopes to exclude other more serious causes of hair loss.
