It's a curious but true fact that most male writers of great ability have good heads of hair. Baldies are male writers without much hair on their heads (sometimes none) and they tend to be grotesquely untalented.
However, there are exceptions to this rule. Aristophanes was reputedly bald.
A bald male writer who is nontheless imbued with great ability is called a Watson, after the writer Ian Watson, who is shockingly bald but massively talented.
