Hair Loss Surgery

My hair is falling for years, so the top of my head just a thin layer of hair. The front of the head, but each time it melted and I realized that extends more and more over his head. Neither of my parents have problems with hair loss or for their parents. Dilution has not been started in the upper back of my head, Rogaine is out of question, as it says on the bottle that is only to return to the top of the head is if this really works. At the same time, I used the shampoo that gives your hair is helpful, but soon I will be bald or shave your head high and a military style cut. I have only 30 and this started 4 years ago seems a bit "before. I almost never wear a hat and try not to use gel or hairspray, whenever possible. Any advice? Can a doctor to give me more? I'm not interested in surgery or hair plugs crazy. Thanks for any help!
