In human society how someone keeps their hair can do many things for how someone perceives said person. It can be used as a thing of beauty to attract, it can show power, style, cleanliness, social standing ever give a first glimpse into someone's interests and possible personality.

I was just sitting doing my own hair for my night ahead and wondered when, how and why this started? Presumably to begin with it was just a matter of hygiene? Hopefully some of you expert Reddit Historians can enlighten me yet again.
