What do Charles Darwin, Michael Jordan, and Yoda have in common? They, like many other historical and fictive individuals, are bald. Scientists have long pondered, why do some people lose their hair, and how can we bring it back? Sarthak Sinha explores the basics of baldness.

Lesson by Sarthak Sinha, animation by Brett Underhill.

    My father is bald. So if this is genetic then there is a slight chance that I won’t be bald. I’m holding on that faith. Lol

    Can anyone help me? I dont have anyone in my family as far as my grandparents of both sides that have baldness. Yet im the only one with receeding hairline and thinning hair. Does that mean my hairloss is not genetic?? By the hairline i can see many tiny baby hairs which are likely my old hair that got shrinked. And if i stop using anti dandruff shampoo, my scalp got flaky and and itchy and spreads over time. If i continue using it. It’s fine. I once got a dermatologist telling me it’s fungal infection causing the hairloss. And another dermatologist was stubborn enough not to hear my sayings and just ruled that i got baldness in my genetics from family history before i really finish talking. Can anybody help me think of a possible cause?

    People go bald because there hasn't been evolutive pressure to combat it. If bald men didn't attract women, they wouldn't reproduce, and all bald men would have extinct. So, while unpleasant, rest easy knowing you won't go extinct.
