How many hairs does the average person have on his or her head and how much does human hair grow in a year?

The amount of hair covering varies from one individual to another. An average person has about 100,000 hairs on their scalp. Most redheads have about 90,000 hairs, blonds have about 140,000, and brunettes fall in between these two figures. Most people shed between 50 to 100 hairs daily. Each hair grows about 5 inches (12.7 centimeters) every year. (The Handy Science Answer Book, compiled by the Science and Technology department of the Carnegie Library of Pittsburgh)
