Why does hair turn gray?
Hair goes gray because pigment cells in the hair base at the roots of
the hair stop producing melanin.
It doesn't matter if you are fair-haired or dark-haired you have the
same chances of getting gray hair. However, it is more noticeable in
darker haired people.
Graying of the hair generally starts at the age of around 30 for males
and 35 for females however since the onset of this phenomena varies
greatly from person to person, age is not the most accurate indicator.
The graying of hair appears to be genetically determined but the
connection isn't at all clear.
So for now, your hair turning gray is just one of those mysteries of
science that we have yet to solve. But salt and pepper hair always did
look distinguished.
Did you know?
Poliosis is the graying of the hair. It comes from polios, the Greek
word for "gray."
