There are multiple causes of hair loss. Some can be metabolic, like anemia or thyroid disease or other internal disease or nutritional issues. Others can be caused by hairstyling, genetics and even autoimmune disease. So, depending on because of your hair loss, a dermatologist can direct treatment appropriate for that cost. Either way, please feel free to see your local dermatologist, and if you do not have one, you may go to AAD.org; there is a tab to search for a dermatologist near you.
