Examining the role of genetics in hair loss

Ever notice how some people tend to age gracefully with a full head of illustrious locks, while others start sporting a receding hairline after their 30th birthdays? While some blame hair loss on stress or lifestyle habits, such as too much smoking or drinking, and others believe certain soaps or shampoos are the culprits, the answer is likely tied to genetics.

As this newly posted AsapScience video explains, the most influential hair loss gene is located on the X chromosome only and, as a result, baldness is partially hereditary and passed through the maternal side. Watch the short clip to learn more about how genes play a key role in hair loss.
