Male Baldness Info

In January my hair started to thin out all over, and hair was falling out all more than usual. Then that slowed down, but I noticed that my hair line at the front and sides is receding.
Is there anything I could be eating or doing that is causing male pattern baldness to affect me early?

Does hair fall increase if you have dandruff?
Whenever i massage my hair at night before the mirror. I see about 50-60 hairs in the wash basin. My hair is only about 1.5-2 inches long. Am I losing my hair? I am 23 1/2 yrs old. Male. I do have dandruff. Is that the cause? or is it baldness. I have baldness in my family??
