Of course, we know that both our hair and nails are constantly growing....but here are secret facts that we should also know about our hairs and nails!

Facial hair grows faster than any other hair in the body: In fact, if the average man never shaved his beard it would grow to over 30 feet during his lifetime, longer than a killer whale.

Every day the average person loses 60-100 strands of hair: Nonetheless, your hair loss will vary in accordance with the season, pregnancy, illness, diet and age.

Women’s hair is about half the diameter of men’s hair: This translates into the fact that men’s hair is coarser than that of women…but this, of course is dependent on race.

The fastest growing nail is on the middle finger: Nail growth is related to the length of the finger, with the longest fingers growing nails the fastest and shortest the slowest.

There are as many hairs per square inch on your body as a chimpanzee: We have lots of hair, only that it’s not obvious on most of us as a majority of the hairs are too fine or light to be seen.

Hair colour determines how dense your hair is: Here, blondes are said to have more hair. The average human has 100,000 hair follicles, each of which is capable of producing 20 individual hairs during a person’s lifetime. Blondes average 146,000 follicles while people with black hair tend to have about 110,000 follicles. Those with brown hair fit the average with 100,000 follicles and redheads have the least dense hair, with about 86,000 follicles.

Fingernails grow nearly 4 times faster than toenails: The nails that get the most exposure and are used most frequently grow the fastest. On average, nails on both the toes and fingers grow about one-tenth of an inch each month.

The lifespan of a human hair is 3 to 7 years on average: While you lose quite a few hairs each day, your hair strands actually have a pretty long life providing they aren’t subject to any trauma. Your hairs will likely get to see several different haircuts, styles, and even possibly decades before they fall out on their own.

You must lose over 50% of your scalp hairs before it is apparent to anyone: You lose hundreds of hairs a day but you’ll have to lose a lot more before you or anyone else will notice. Half of the hairs on your pretty little head will have to disappear before your impending baldness will become obvious to all those around you.

Human hair is virtually indestructible: Aside from its flammability, human hair decays at such a slow rate that it is practically non-disintegrative. Hair cannot be destroyed by cold, change of climate, water, or other natural forces and it is resistant to many kinds of acids and corrosive chemicals.
