propecia does something if you are experiencing male pattern baldness. although your hairline has receded a little, you do not seem to have male pattern baldness. tough to tell since your hair is so short, though. however, if i had your hair at 31, i wouldn't bother.
the bump on your head is likely a sebaceous cyst. i had two, but it's not related to hairloss. it can easily be removed by a dermatologist, but the procedure is usually not covered by insurance. i spent about $550 getting my cysts removed since they were continuing to get bigger.
