Why do you have red hair? It could be your hair color
The idea that red hair could be linked to one’s biological makeup is nothing new.
People have been thinking about this since at least the 19th century, when French biologist Jean-Jacques Rousseau speculated that the color red could be a sign of genetic similarity.
Some geneticists theorize that the genetic differences between two people’s red hair, called color-specific variation, could reflect the amount of time they spent in a certain habitat, or the intensity of sunlight.
“When it comes to our red hair we have a lot of red hair in this country and a lot less in other countries,” said Dr. Richard H. Stebbins, professor of molecular genetics at Emory University.
“So it’s not as if we’re all red hairheads.
It’s more like, ‘This color is important to me.'”
But, the idea of a genetic connection between red hair and skin color has never been conclusively proven.
And although some studies suggest that redheads are more likely to have brown skin than their darker-skinned counterparts, it’s been unclear if this difference was due to genetic differences or simply the way that redness varies depending on how the skin is exposed to the sun.
(For more about skin color, see our previous coverage on why people with darker skin are more tan.)
So in the 1960s, Dr. Stempel decided to test his theory by studying hair color in a group of redhead women and compared them with those in a larger group of non-redheads.
The results showed that the women with darker hair were more likely than the other women to have redness around the eyes, eyebrows, and temples.
But Dr. H.J. Stelmach, the lead author of the paper, wasn’t convinced.
“I thought, ‘No way,'” he said.
He and his colleagues decided to study redheads because redheads’ skin is generally more tan than non-reddheads.
But this didn’t explain why the redheads had more red than the non- redheads.
Instead, the researchers hypothesized that the reason the reds had more color around their eyes was because they had been exposed to more sun.
“The redheads who had been in the shade more were the ones who were exposed to higher levels of UV radiation,” Dr. W.A. Stahl, a professor of medicine at the University of Michigan, told The Daily Beast.
“They had been tanning in the sun for a longer time, and it gave them more melanin, so their skin had been developing that much more rapidly.”
When Dr. Draso and his team looked more closely, they noticed that the researchers’ results were not the same for redheads as they were for non-dudes.
“In redheads, we did find that the redder their hair was, the higher their melanin levels were,” he said, noting that they didn’t have any difference in the color of the skin between redheads and non-ruds.
“It was a little surprising to me that there was no difference in their skin tone between reds and nonreds.”
The researchers also looked at the effects of red-haired people on their skin color.
In a study published last year, Drs.
Stelsmach and Stebbs found that the higher the redness of the hair, the more the hair affected the skin.
“We thought that red was probably more damaging than nonred hair,” Drs, Stelsma, and Drasso told The Associated Press.
“But this didn [t] appear to be true.”
They theorized that because red hair can be more damaging to skin than nonreddish hair, it may be more effective at fighting the effects that UV radiation has on the skin and causing damage.
But, despite the fact that red people have more melanosomes in their body, the scientists found no evidence that red-hairs’ skin color affects their skin.
The team also found that people with red hair had higher levels and greater levels of red pigment in their hair than nonpeople with red hairs.
This indicates that red is more harmful to the body’s natural protective systems than nonhairs, the authors said.
So, Drasos conclusion that red skin was more harmful than nonruds is based on the same basic premise that it’s more harmful that non-huds, but it doesn’t explain the fact it was more damaging for red people than nonhumans with redhair.
The study is the first to look at how the red hair affects the skin’s ability to absorb and store vitamin D. The researchers hypothesized this would be due to the fact red hair is darker and more absorbent than nonhair.
“If you’re going to get vitamin D in your hair, you need to take it from your scalp,” Dras, Stelms, and Stelum said. “Red
