Red Hair: 4 Risks and Facts

As we know, people of Caucasian race have a variety of hair colors, ranging from blonde, brown to red. The last hair color is the rarest. It is estimated that only 2 percent of the entire human population has red hair from birth.

However, there are health risks that accompany redheads. From the risk of skin cancer to endometriosis. Find out more here!

Red Hair Risks

Has links to genetic mutations that cause birthmarks

Research in 2012 \revealed a link between birthmarks and red hair. More horrifyingly, this birthmark can turn into skin cancer, especially if its size increases.

More at risk of endometriosis

Meanwhile, other studies cite a link between hair color and the risk of endometriosis. Redheads have a higher risk of endometriosis, a condition in which tissue from the uterus grows outside the uterus. As a result, women who experience it will experience pain.

This is evidenced by a 2006 study involving more than 90,000 women aged 25-42. The study revealed that women with red and fertile hair had a 30 percent higher risk of endometriosis than women with other hair colors.

Greater risk of skin cancer

People with red hair only about 2 percent of the worldwide population, and 16 percent of melanoma (skin cancer) sufferers have red hair. The researchers found that a variation of specific genes associated with the cause of having red hair (and freckles on the face) was shown to have a 42 percent faster rate of forming skin cancer–causing genetic mutations. It’s like getting extra sun exposure for 21 years.


The owner of red hair is also disadvantaged against pain-related matters. A study published in the Journal of The American Dental Association in 2009 found that redheads are more afraid of dentists. Red hair also requires a larger dose amount to numb the pain, likely due to genetic variations that regulate how the body metabolizes drugs.

Red Hair Facts

Rarest in the World

Since red hair is only owned by 2 percent of the human population on Earth, that’s why natural red hair color is the rarest hair color in the world.

Red hair is the result of a mutation of the MC1R gene.

If the father and mother both have this MC1R gene, then there is a 25 percent chance the child will have red hair, even if the parents do not have red hair.

According to the researchers, although only 2 percent of people have red hair, there are about 4 percent of people who have genes that produce red hair.

If a person has freckles or tanned spots on the face, it is possible that the person carries the MC1R gene in his body.

Of all the redheads, there is an even rarer combination, namely a person who has red hair and has a blue eye color.

Usually when a person is aging, his hair will be overgrown with gray hair or white hair, and other hair colors will also fade.

But this is experienced by people who have colored hair other than red.

Yes, people with natural red hair do not experience a change in hair color to gray.

Getting older, the color of red hair will still fade, but eventually become blonde.

Then, the owner of the red hair has fewer strands of hair than the owner of the other color hair.

On average, dark-haired people have 140,000 strands of hair, and blondes have 110 strands of hair, while redheads have 90,000 strands of hair.

On the other hand, the strands of red hair tend to be thicker, so the volume of his hair will still look thicker.

Producing Vitamin D with Little Light

Generally, the human body makes vitamin D by processing it from sunlight.

So when we are exposed to morning sunlight, the skin will produce vitamin D.

However, owners of red hair often experience burning skin in the sun.

But, people with red hair do not need to look for a lot of sunlight to be able to meet the needs of vitamin D in their body.
