Color, Texture, Shine: All About Hair Biology

WRITTEN BY: Xuan Pham

Hair is one of the most prominent aspects of self-identity. Whether it's buzzed, shaved, braided, or dyed, hair is a big part of any culture, and it's how people convey themselves to the world. Indeed, while all mammals have some hair, humans easily win on the amount of time and money we spend grooming our locks.

But why do some hair grow curly, while others are pin-straight? And why is it that no one is ever born with purple or blue hair? Why does the hair on our head keep growing while hair on other parts of our body seem to stop at a certain length? Find out the answers to these questions and all other hair-related conundrums in the video!
