I think you're looking at the result and trying to backtrack to the wrong path. When I read it, I think you have more cases of crazy female blondes due to most blonde women are considered the pinnacle of beauty so they have their pickings of the top men.
As we know, abundance of options for women drives them completely mad as it forces them to decide, which goes against their biology. That's what happens in China today where post-wall women are so delusional, it sounds fake...

I know it's random but everyone knows the hot crazy matrix. Being blonde makes men enable your craziness to unseen levels before modern society.
There's a good episode of how I met your mother series, were there is an explanation that Jeanette, a complete blonde psycho girlfriend of Ted, acts crazy. Later in an episode is revealed that Ted has been enabling all of it, every outburst, never punishing her when she acts that way.
