Here we have some interesting examples of combs used throughout the centuries of history of hair. Designed to keep the hair in order, neat, and with an agreeable appearance, and in some cases with the second intention -as we can see in the doubled-sided combs- of keeping the head free of lice and other parasites. From rudimentary prehistoric combs to the amazingly elaborated designs of Middle Ages and further centuries, they are testimonials of how people concerned about hair styles' appearance.
