Why do skin tones vary, hair turn red, and beards clash with scalp hair? Biological anthropologist Tina Lasisi explores melanin, UV radiation, freckles, vitiligo, and the science of hair samples. Along the way, she tackles sunscreen, ashiness, skin-bleaching pressures, and how human variation gets misunderstood.
