Einstein Hair

It seems that to properly convey that your male character is an Absent-Minded Professor or a Mad Scientist in fiction, you only need one thing: give him Einstein-esque hair. Bonus points if you go for the complete look. Additional bonus points if he uses a Van de Graaff generator or a Tesla coil instead of combing. And it actually makes sense given that: Albert Einstein was both an Absent-Minded Professor and a scientist (mad or not, it is open to interpretation). He is one of the most (if not the most) famous scientist in history. His hairstyle was really... idiosyncratic. Contrast Wild Hair, which also indicates indifference to society's opinion, but otherwise has quite different connotations. Sub-Trope of Messy Hair. Compare Labcoat of Science and Medicine. See also Memetic Hair, which this style can be an example of.
