Textbooks were wrong: Scientists reveal the surprising way human hair really grows

Hair may grow in a completely different way than scientists once believed.

Advanced 3D imaging revealed a spiral movement of cells that generates this force. The finding could change how scientists study hair loss and design future treatments.
