Balding, Toupees, and Respect

So I've started to notice that my friends are losing there hair. I'm not yet, so nothing to owrry about too much. But, someday I probably will face this problem like most men do.

What is the msot repectable way to deal with hair loss? Is there any way to justify something like transplants or even a toupee? How have 2+2ers dealt with this? Do I just have to accept balding as part of the male way of things?
