As a (somewhat insecure) Asian guy, I have to say that skull shape matters. Some of us tend to have flat back of heads, which is less than ideal in Western beauty standards.

In my younger years I had my head buzzed to a near monk length (I was pretty obsessed with Buddhism at the time) and it did not look right. Friends commented that I looked 'intense.' While perfect for the monk persona, I was going for the more badass tough guy look. It was a tough few months.

Also, facial hair helps a lot, which I am unable to grow.

So I look forward to hair plugs if I ever start going bald.
