Why are some people bald?
« on: 14/06/2012 10:30:02 »
Jon Kelling  asked the Naked Scientists:
   My son would like to know:

Why are some people bald?

He's 5, his name is Landon, and he would get a kick of hearing his
name on the air :)

Thanks!

Jon

P.S. love the show! Thank you!
What do you think?

Hair loss can occur due to hair pulling, disease or medical treatment. Gradual hair loss occurs with age.

But the most common hair loss is male-pattern baldness, and is determined by genes which are triggered by male hormones. This constricts the hair follicle, so a normal, pigmented hair cannot grow.
The genes are active in a specific region of the scalp, leading to a distinctive pattern of hair loss.
