Are you searching for facts about hair? Are you working on a lesson plan about hair? Has your three year old asked about hair and you would like to share some trivia? Here are a few random facts for kids about hair.
Hair is incredibly strong.
Hair can stretch by 25% of its length before it snaps. A single strand of hair can support 2 1/2 pounds. That means, if you weighed 160 pounds, you could hang from a cord made of only 1,000 strands of hair.
The average human head has 100,000 hairs.
The amount of hair varies from person to person, but the average is 100,000. Brunettes (those with brown hair) have about 108,000 strands and blonds have about 150,000. Redheads only average about 90,000 strands of hair.
Blond hair grows at a faster rate than brown hair.
Scientists have determined that blond hair grows faster than brown hair. Often blond haired men do not need to shave as often as dark haired men.
Hair is dead.
Hair is not alive. The follicle (the root of the hair) is living and pushes hair cells up through the skin.
Each strand of hair grows without stopping for about six years.
Each hair on your head grows consistently for six years. Then, it rests for a few months before falling out. About 10% of the hairs on your scalp are resting.
People lose about 40-80 strands of hair every day.
Typically, most people loose between 40 to 80 strands of hair each day. Some conditions, such as pregnancy and anemia, can cause hair to fall out at a faster rate. Also, some medications can contribute to hair loss. And, chemotherapy (treatment for cancer) can cause patients to lose all of their hair.
Nearly all skin on most people has some hair.
While it is not very noticeable, hair grows on most parts of the human body. The exceptions are the palms of the hand, soles of the feet, lips, and mouth.
Hair is the fastest growing tissue in the human body.
Hair is the fastest growing tissue that humans have. Bone marrow is the only tissue that grows at a faster rate.
Over 50% of men by age 50 have significant hair loss.
More than half of all men by age 50 will become bald. Some men will become bald much earlier, even in their 20’s.
Hair can be used to solve a crime.
If even just one strand of hair is left by a criminal at the scene of a crime, it can be used to solve the crime. Forensic investigators can match the DNA. They can also do this with skin particles, sweat, blood and bodily fluids.
