By Emma FaganRead more The word “cynosis” refers to the redness of hair that forms when certain cells of hair are exposed to light and oxygen.
It is thought that the pigment of hair has evolved to protect the skin against external threats such as the sun and ultraviolet rays.
The colour of the hair, on the other hand, reflects the amount of light absorbed from the hair follicle.
The term cynosis is also used to describe the colour of hair of a person’s face or hair that falls on the sides of the head.
It can also refer to the dark hair that runs across the back of the neck and is typically white.
In Australia, the term “cynomia” is also sometimes used to refer to people who are Caucasian or Native American, although it has also been used to denote African American hair and hair colour.
People who are not “Caucasian” or “Native American” are sometimes called “dark hair”.
This term is used to identify hair colour in people who have dark hair, but are not white.
Some people describe their hair colour as “cynosider”, which is short for “cynthesis”.
“In general, people who wear a lot of black, or dark hair can be referred to as a cynotic,” said Dr Sarah Bowerman from the University of Melbourne.
“They have the same condition as someone who wears a lot more white hair.”
Dr Bowermans research has also shown that people with darker hair tend to have darker skin.
“We know from previous studies that the more melanin there is in the skin, the darker the skin is,” she said.
“The more melanon you have, the more you have to produce, and the more pigment you have in your skin, that means you’re going to have less pigment.”
According to the World Health Organization, melanin is a protein that can absorb light.
“The more pigment in the melanocytes, the greater the absorption of light,” Dr Bowermons said.
However, people with light hair are at risk of developing melanoma, which is a skin cancer.
Dr Bowers studies have also found that people who carry excess melanin in their skin, called “pigmented skin”, are more likely to develop skin cancer than people with lighter skin.
But Dr Bowers says it is not necessarily the colour that causes melanoma.
“It’s more likely that there’s some sort of hormonal effect, or the melanin-producing cells of your skin are not producing enough melanin,” she explained.
“If the melanocyte is not producing a lot, you can get darker hair, which may increase your risk of melanoma.”
Dr Kari Lippmann, a dermatologist at University of NSW, said she would like to see a study comparing the colour, length and density of hair in black and white Australians.
She said she was unsure if the research would be a good indication of “cynorosis”.
“There’s been some research done that has looked at the differences between black and whiteness in Australian people,” she told ABC Radio Melbourne.
“I’m not sure how that would work.”
