Eye-catching, no doubt. Among a majority of brunettes, chestnuts, and some blondes, redheads stand out.
There is no real figure for the number of them in the world, but it is clear that they are more numerous in countries such as Ireland (10% of the population), Scotland (about 13%) and Wales (approximately 10% of the population). the population). Russia, a name that would translate to Land of Reds (or Redheads), boasts of hosting a high percentage of redheads in the Kazan region.
Admired in some countries and feared in others, being red-haired is complicated because it is a recessive genetic variant. That is, there is a 25% chance of being if both parents are carriers of the gene (even if they are not redheaded), up to a 50% chance of being if one of the parents is a carrier of the gene and the other is redheaded; and up to a 100% chance if both parents are redheaded.
A study reveals a rather striking curiosity: when they go to the dentist they feel the same pain as any other person, what happens is that according to recent studies, they need different doses for some medications.
For example, some anesthetics have less effect on them (they need 20% more doses than dark-haired people) and vice versa, with other substances they need fewer doses for the same effect. But if they have more pain when they go to the dentist, it is because the typical dental anesthetic (such as Novocaine) does not have enough effect on them, and it is not because they are "more sensitive" to pain. The specific reason for this is unknown, but it is thought that a connection to the MC1R gene mutation could be to blame.
Unlike those with dark, brown, or blonde hair, redheads don't have to worry about graying until very old. When those gray hairs begin to appear for the rest, the red hair turns blonde due to the contrast between the two colors. Also, they have less hair overall, but it is much thicker.
Regarding the sun, the main advantage of this genetic mutation that characterizes redheads is the ability to synthesize vitamin D in places with very little incidence of sunlight.
On the other hand, the fascination provoked by their appearance has not always been positive and history has subjected them to the same hardships as any group or individual that has not conformed to the norm.
Even today, in the 21st century, many children are bullied because of their hair or skin color. For this reason, most of them just want to be noticed for being as handsome, as normal or as flirtatious as the rest of their peers. No distinctions.
