It's your genes, man: I'm really sorry that anybody told you that keeping your hair clean or using stuff to give it shape is going to make you bald. Male pattern baldness is genetically programmed and generally runs with how much chest hair you're naturally blessed with. You can slow it down with medications, or embrace it, shave your head, and get really physically fit -- nothing a man can do looks better.

As above, I trust that you are asking about classic male pattern baldness rather than hypothyroidism, alopecia areata, or telogen effluvium.

It's heredity--the : gene causing male pattern baldness is on the X-chromosome. That means your father had nothing to do with it because there are very few genes on the Y chromosome. It doesn't matter if your father had a full head of hair. What matters is if your mother has a brother with a full head of hair and your mother's father also. The culprit is dihydrotestosterone, made from testosterone by skin receptors.

Periods of severe stress can also lead to hair loss but this is typically temporary and resolves when the stress is dealt with.
