Redheads, when compared to blondes or brunettes are more than twice as likely to avoid going to the dentist. The same genetic variant that explains their hair also makes them more resistant to local anesthesia, such as Novocaine and they might need as much as twenty percent more as reported in Journal of the American Dental Association.
Researchers report that, on average redheads are also more sensitive
to heat and cold and three times more susceptible to skin cancer
than the rest of us.
Other disorders, all backed by studies, that disproportionately
affect redheads include: Parkinson’s disease, Endometriosis, and
At a recent seminar on hair color and health, Scottish researcher
Jonathan Rees reported that throughout history the “ginger gene” may
have “played a big role” in protecting many redheads from rickets
(soft, weak bones triggered by vitamin D deficiency).
Unlike blondes and brunettes, their natural red hair retains its
original color longer than any other hair color, although eventually
it tends to turn blond, and ultimately white. On average, redheads
have thicker hair, but fewer strands (about 90,000), compared to
blondes (110,000) or brunettes (140,000).
The world’s highest rate of redheads is found in Scotland, where an
estimated 13 percent of Scots, about 650,000 people have red hair
compared to 4 percent of Europeans and less than 2 percent of the
global population, according to STV News. In the US, there are an
estimated 6 million redheads. Unrelated hairy fact - The leaders
of Russia have been alternately bald then hairy since 1881 through
the first Putin leadership.
