I think that if you are losing your hair you have 3 choices: Shave your hair really close and find a way to make that your look, do a comb-over and look like a jackass, or spend a bunch of money and do what I am doing. This will only be part 1 though, just because you transplant some hairs doesn't mean the other ones aren't going to get weaker.
The doc today was telling me that a lot of people could prevent this sort of thing by using tegrin or monoxidil or whatever it is called. Once the hair is already falling out and weakening it is too late for that product to do anything. There is an oral one that you can take but one of the side effects is that it is basically the opposite of Viagra so needless to say, it isn't very popular.
