WARNING - This post features the traditional art of making things with human hair, you might be totally grossed out by this. I don't really care. I like it.
When one thinks of Hair art, usually the Victorian Era comes to mind. While they raised the act of creating with human hair to a high art, and obsessively traded in momentos of human body parts (teeth, for example), the Victorians did not invent the art. A number of old folk traditions use hair in the making of charms, spells, sigils and the like. Both for protective and harmful magics.
