Natural hair color may be more popular than you think, but the science behind how to achieve that natural look remains a mystery.
But now scientists at the National Geographic Society have published the results of a study that shows that the science may have been behind that popularity.
Here’s what you need to know.
What Is Natural Hair Color?
“Natural hair color is the result of a combination of genes, chemical reactions, and environment,” says Michael Wachter, a professor of entomology at the University of Georgia and lead author of the study.
“It’s very similar to natural hair, except you don’t get a little bit of hair in there.
The hair that grows naturally is the hair that has been exposed to the sun, to sunlight, to water, and to the air.
Those are all the things that give hair its natural color.”
Scientists have known about hair color for hundreds of years, but it was only recently that researchers realized that it can be controlled by genetics and environment.
The main difference between natural hair and synthetic hair is that synthetic hair comes in a wide range of shades, and the hair color depends on which type of hair it’s growing in.
Hair color can vary in several ways, and scientists think that these differences may be linked to genetics, environment, and even lifestyle choices.
For example, people with darker hair may have higher levels of a gene called melanosome-1, which is involved in the production of melanin, the pigment that gives the skin its red color.
The same gene also plays a role in the color of the outer hair follicles, which are part of the hair’s inner coat.
These follicles help to form the protective layer that makes the hair feel soft and soft.
But when the researchers looked at the genetics of the people in the study, they discovered that most of the individuals in the samples had genes for a gene that causes hair color to be controlled.
They found that the average African American male had one of these two genes—a gene called SHH1.
That gene is associated with dark hair and dark skin.
When SHH-1 is expressed, it produces a specific enzyme called melanin reductase, which turns melanin into more melanin in the hair follicle.
This process results in a white hair color.
“This gene was in my family,” says James Loy, a doctoral candidate in entomography and director of the entomological research center at the Smithsonian Tropical Research Institute.
“I was able to find this gene and figure out how to get my own genes to do this.
So the gene that is linked to hair color, which causes hair to be a little darker than it should be, is also the gene responsible for the color that I have.”
Loy says he was able find that gene in a genealogy of his ancestors, and it turned out that his great-great-grandparents also had the gene.
“That gene was a very interesting genealogy,” he says.
“And the reason why it was so interesting was that I was able get a sample of my own genealogy, which had the exact same gene as the genealogy I was looking at.”
What Are Some of the Differences in Natural Hair Colors?
“We can’t tell exactly what causes hair colors to be different in the human population,” says Wachner.
“But we do know that there are some differences in hair color among people.
We can tell because we can measure the chemical makeup of the melanin produced by different people.
For instance, in people with dark skin, the melanins produced by hair cells are very dark.
That’s because those melanins have been exposed by UV rays.
But in terms of the chemistry of hair, there are chemicals in our hair that may be different from the hair we have. “
In terms of hair color we don’t have any way to tell,” Wachters says.
But in terms of the chemistry of hair, there are chemicals in our hair that may be different from the hair we have.
“When you’re growing a hair follicular cell in the lab, there is a reaction that occurs where a molecule called melatonin is synthesized.
That molecule is what causes that dark hair color in the natural hair color that we’re seeing.”
That’s why, in this study, scientists also looked at hair chemistry in samples from individuals with and without dark skin and dark hair.
Hair that had been exposed in the laboratory to light was darker than hair that had not.
“We found that these people had higher levels [of melatonin], and it turns out that this is a chemical that affects the way our hair follicules function,” Wachester says.
Melatonin is a hormone that stimulates the production and release of a protein called melanocortin-3, which also plays an important role in melanin production.
And melatonin levels were also higher in people who had darker skin.
“What we’ve found is that people who have darker skin have higher melatonin, and
