16 Fun Facts About Your Hair
The hair outside your scalp is dead, yet people continue to fuss over their hair color, cut and style. As humans, we are often defined by the dead tissue on top of our heads. Obsessing over a bunch of tiny strands of hair is a strange concept for sure, but it’s also an interesting part of your body. For centuries people have studied and styled their hair, and over the years we’ve learned a couple things. Here are 16 fun facts about the hair growing on top of your head.
-Hair is dead. Kind of. Under your skin, hair grows from tiny follicles that are connected to a network of blood, nerves, and muscles. A single follicle can produce up to eight strands of hair.
