9 Strange Facts About Redheads You Never Knew Before
While only about 2 percent of people have naturally red hair, there are plenty of fun facts about gingers.
They’re harder to anesthetize
A small study in the journal Anesthesiology found that redheaded women required 19 percent more of the anesthesia desflurane to be put to sleep than women with dark hair. Some scientists think that the protein mutation that causes red hair and fair skin makes redheads more sensitive to pain and therefore it’s more difficult to anesthetize them.

They have more sex than blondes or brunettes
“The sex lives of women with red hair were clearly more active than those with other hair colors, with more partners and having sex more often than the average,” Hamburg sex researcher Professor Werner Habermehl told the Daily Mail, after leading a survey of 6,000 German women through the Hamburg Medical Research Institute in Germany.
They’re at risk for melanoma
According to a 2010 meta-analysis in the International Journal of Cancer, a fact about redheads is that they are about two and a half times as likely to develop the dangerous skin cancer as people with other hair colors.
Scientists have used birds and boars to understand redheads
In their attempt to understand how pheomelanin, the pigment that makes hair red, affects gingers’ health, scientists have examined similarly auburn-tinted feathers and fur. The results? Boars taught the experts that redheads may be at high risk for cellular damage from free radicals, and a study of more than 1,400 species of birds suggested that the pigment may be associated with smaller brain size.

They’re not going extinct
As science journalist Maggie Koerth-Baker writes, “Actually, redheads are stealthily infiltrating the rest of humanity.” Here’s her proof: Even though only 2 percent of people have red hair, 4 percent have the gene that makes redheads. (If you have freckles, you’re probably a carrier). So, while two redheads won’t produce a brunette, two brunettes could produce a redhead. Did you know that red hair and blue eyes are the rarest hair and eye color combination in the world?
They’re more likely to be left-handed
Another fun fact about redheads, they’re more likely to be left-handed. Both of these characteristics come from recessive genes, which typically come in pairs. These are the surprising benefits of being left-handed.
They won’t go gray
One of the many facts about redheads is that their hair will never turn gray. The pigment in their hair that causes it to be red will just fade over time, causing their hair to turn blonde or white, but never gray. Are you ready to go gray? Here’s what happens to your hair when you stop coloring it.
Redheads have less hair
People without red hair have about 140,000 strands of hair, while people with red hair have only 90,000. But red hair tends to be thicker so it looks just as full. Find out the hair tricks from around the world that you should be using.
