“To have unruly hair is to indicate a separation from conventional society, a sign of someone who flouts the rules, whose ideas are different from the norm and whose long hair is a symbol of liberation from the constraints of society. This is not a recent symptom of societal changes but predates the time when people wore flowers in their hair in the 1960’s and 70’s. Traditionally, witches and wizards had unruly and disheveled hair and lived apart from their neighbours, as did the hermit, whose long robe and tangled hair are an archetypal uniform. The ‘mad professor’ who teeters between genius and insanity is given away by his hair, which stands on end.”
