1 Red hair is a result of a mutation of the MC1R gene, on chromosome 16.
I wish I had red hair. My hair is black... - TwilightKitsune
2 Red hair with brown eyes is the most common combination. Red hair with blue eyes is the most rare.
I actually thought it was the opposite, or that red hair with green eyes was the most rare.
3 Redheads are more sensitive to cold and physical pain, and can also be more emotionally sensitive.
4 Redheads don't grey; they fade.
Hmm, interesting facts about redheads. Now I know more about redheads thanks to this list. But as for this fact, it's pretty miraculous that redheads won't have to put up with grey aging hair like the rest of the non-redheads do. - ModernSpongeBobSucks
My grandmother had her red hair all the way till she died at age 72.
5 Redheads comprise less than 2% of the world's population.
6 The theory that redheads will eventually go extinct is false. The gene won't die out. But redheads may become increasingly rare as the human gene pool spreads out.
7 Scotland has the highest proportion (13%) of redheads.
I should go to Scotland one time then - Userguy44
I thought it would be Ireland.
I read that Scotland has the most redheads, but Ireland has the largest gene pool for red hair. - Crwth
8 On average, redheads require about 20% more anesthesia to obtain satisfactory sedation. They also require more pain medication.
9 Redheads are more likely than other people to be left handed.
10 Red hair was considered a sign of witchcraft in 15th century Germany. During the witch trials, 45,000 red-haired women were estimated to have been burned at the stake.
11 Because natural red hair holds its pigment better than other colors, it is harder to dye.
12 Redheads actually have less hair, on average, than brunettes or blondes. Brunettes average 140,000 strands of hair, blondes 110,000, and redheads about 90,000.
13 Redheads bruise more easily.
14 Natural redheads tend to be loose jointed and, in turn, more flexible.
I know this is true for me. My wrists use to pop out of joint very easily when I was little.
15 Perfumes applied to redheads' skin smell differently because of the different biochemistry of the body, which scientists are still trying to understand. Perfumes don’t last as long on redheads' skin either.
16 Hitler banned the marriage of redheads in order to prevent "deviant offspring."
17 Greeks believed redheads turned into vampires when they died.
18 Red hair is a recessive trait and may only show up in every second, third, or fourth generation, coming as a surprise to new parents.
This, for me. Neither of my parents have red hair, but both of my grandmothers did. It skips generations.
