Honestly, there isn’t much I can tell you just based on what you’ve given me. I’m not even really sure what your question is. Your dandruff isn’t your cause for hair loss.
See a doctor, get your hair mapped for miniaturization, and if you have male pattern baldness (which is what it probably will be based on your family history), Propecia (finasteride 1mg) is the best medication to use.
