The hair you see outside your scalp, physiologically speaking, is dead. It has no blood supply, nerve supply or muscles. If you cut your hair you feel no pain, it does not bleed, nor does it pull a muscle when stretched. However for a dead fiber, it is also quite remarkable.

Check out these interesting hair facts:

Healthy hair is highly elastic and can stretch 30% before snapping
Hair can absorb its weight in water
An average head of hair when twisted together can support 23 atoms of weight (approximately 100 people.)
Hair is stronger than copper wire of the same diameter
Hair cell reproduction is the second most prolific in the human body; bone marrow being the first.
This is the reason why hair is extremely sensitive to changes occurring in the body
Hair is composed mainly of keratin (protein consisting of amino acids) and moisture
Each hair grows from a follicle, which is an indentation in the skin. We are born with a specific number of follicles.
Each scalp follicle on average grows 20-30 hairs in a lifetime
The size of the follicle determines the thickness and length of the hair
Each follicle has it’s own blood, nerve and muscle supply
Hair grows about 1.5 inches (1.25cm) per month
Hair grows faster in the summer, during sleep and between the ages of 16 to 24
The growth phase of hair (anagen) lasts an average of three to five years so a full-length hair averages 18-30 inches (45-75cm.)
About 90% of your hair is in the anagen (growth) phase
