You are a man with a long history of hair loss. With severe and generalized hair loss and hair miniaturization, you may be suffering from a systemic disease with skin and hair symptoms. Your doctor must take a thorough medical history, including history of past medical conditions and medications used, and perform a physical examination (perhaps the most important key to diagnose your problem). Getting your hair mapped out for miniaturization is critical to determine if the hair loss is patterned hair loss, which may have more typical genetic causes. There is really not a set of tests that could be suitable for every situation. Leave this to your doctor and get back to us if you are still having questions after your evaluation.
