What type of doctor should I see about hair loss?

Everytime, I saw the article about hair loss and they also advise people to consult with doctor. However, they never mention what type of doctor should we visit? Does anyone visit doctor and get good result? What is my expectation?What type of doctor should I see about hair loss?
You would need to see a Dermatologist, since hair is an extension of the skin.What type of doctor should I see about hair loss?
They mean just your regular physician, but that means they just want someone to rule out any illnesses. Some people grow a little bit of feathers using Rogain, but not a lot of hair growth. If you do not have a medical condition or bad stress causing the hair loss, then cut your losses, get a short haircut like others losing their hair (its good looking too) like john travolta, et. al., orrrr go to a reputable hair replacement specialist. They cost big $$$ though.... If all else fails, some men look great bald.
a regular doctor
