5 Interesting Facts About Red Hair


After sharing with you the unbelievable beliefs people in the middle-ages had about red hair, lets talk about some actual science behind the red haired folk.


1) Only 1-2% of humans have red hair.

Apparently, having red hair is relatively rare, so you better be nice to people with red hair because they’re special.


2) People with red hair have twice the risk of developing Parkinson’s disease.

Researchers believe this is because red haired people are fair-skinned and therefore avoid the sun as much as possible. This results in a lack of Vitamin D, which makes them twice as likely to develop Parkinson’s disease and Multiple Sclerosis. This is yet another reason to be nice to your local red head, and maybe alert them to the fact that they need to take some vitamin D supplements.


3) Red hair is often much thicker than any other colour of hair.

On average, blondes have about 140,000 hairs, while redheads have about 90,000 strands of hairs. However, both have the same volume of hair. Which means that if you were going to make a rope made of hair, red hair might be your better option.


4) The red pigment in red hair is potent, and it is more difficult for red haired people to dye their hair different colours.

Unless they are bleaching their hair. Bleach doesn’t care what colour your hair is.


5) Some researchers believe that the red-hair gene played a crucial role in the health of people who lived in cold and cloudy climates.

People who have red hair are usually light-skinned people, which makes them sensitive to sunlight. Normally, this means they will get sunburnt much quicker, and it causes them to avoid the sun. However, in cold and cloudy climates, it was critical to be sensitive to any sunlight, because there was not very much of it. This allowed red hair people to live and thrive in cold and cloudy climates because they were still able to absorb enough vitamin D from the nearly non-existent sunlight in order to be healthy.
