20 Weird Things You Didn't Know About Your Hair
If you think you
know everything there is to know about your hair, think again. You may know how
to style it or whether you want to finally get those bangs you’ve been thinking
about at your next salon appointment, but there’s a lot of weird stuff going on
up there that we rarely give a second thought. These 20 weird hair facts may
just blow your mind, or at least make you rethink the extent of your hair
knowledge.
1. Hair is made up
mostly of keratin, the same protein animals’ horns, hooves, claws,
feathers, and beaks are made of.
2. When wet, a healthy
strand of hair can stretch an additional 30% of its original length.
3. Hair grows slightly
faster in warm weather, because heat stimulates circulation and encourages hair
growth.
4. All hair is dead, except
for the hair that’s still inside the epidermis of your scalp.
5. Hair contains
information about everything that has ever been in your bloodstream, including
drugs, and is one of the most commonly used types of forensic evidence.
6. The only thing
about you that can’t be identified by your hair is your gender—men’s hair and
women’s hair are identical in structure.
7. Black is the most
common hair color. Red is the rarest and only exists in about 1 percent of the
world’s population, with blonde hair found in 2 percent.
8. As soon as a hair
is plucked from its follicle, a new one begins to grow.
9. Hair is 50 percent
carbon, 21 percent oxygen, 17 percent nitrogen, 6
percent hydrogen, and 5 percent Sulphur.
10. Hair can grow
anywhere on the human body except for the palms of hands, soles of feet, eyelids,
lips, and mucous membranes.
11. Goosebumps from
cold or fear are the result of hair follicles contracting, causing the hair and
surrounding skin to bunch up.
12. The average number
of hair strands varies by natural color, with blondes having the most and
redheads having the fewest.
13. The scientific term
for split ends
is “trichophilia’s.”
14. Aside from bone
marrow, hair is the fastest growing tissue in the body.
15. Balding only begins
to become visible once you’ve lost over 50 percent of the hairs from your
scalp.
16. At any given time,
90 percent of the hairs in your scalp are growing, while the other 10
percent are resting.
17. A single hair has a lifespan of about five years.
18. Hair acts as a
layer of thermally insulating protection for our heads, which lack the
insulation that fat provides for the rest of our bodies.
19. Eighty percent of
Americans wash their hair twice a day.
20. Each strand of hair can support up to 100
grams in weight. Multiply that by the average 100,000 to 150,000 strands on
each head, and your entire head of hair could support the weight equivalent to
two elephants.
It is within the human’s
capacity to get the healthy hair with the only condition you must take out few
minutes for yourself every day. These few minutes of your invested time
can become a lifelong asset for us.
