Hair

Hair is a filamentous outgrowth of the skin found only in mammals.

The speed of hair growth is roughly 11 cm/yr.

The average human head has about 100,000 hair follicles.

Older people tend to develop grey hair because the pigment in the hair is lost and the hair becomes colourless.

Grey hair is considered to be a characteristic of normal aging.

The age at which this occurs varies from person to person, but in general nearly everyone 75 years or older has grey hair, and in general men tend to become grey at younger ages than women.

In an attempt to lessen the stigma and bullying associated with being a copper-top, they've created a home DNA test so people can check if they carry the recessive gene. The hope is that someone who finds out they could have a red-head child would be less likely to rip on people who do have Ronald McDonald colored hair. Patrick Jones has the story.
