If you've got red hair, it's time to embrace and celebrate because National Love Your Red Hair Day is Tuesday, November 5.
While World Red Head Day is on May 26, redheads are so great that they get two unofficial holidays each year.
National Love Your Red Hair Day was started by two redheaded sisters named Adrienne and Stephanie Vendetti. They both are co-founders of How to be a Redhead and submitted the day as an unofficial holiday in August 2015. The day is celebrated annually on Nov. 5.
So to help everyone celebrate, here are 12 fun facts about redheads:
- Less than 2% of the world's population has red hair. The highest concentration of redheads is in Scotland (13%), followed by Ireland (10%).
- Having red hair and blue eyes is the rarest hair/eye color combination possible. The odds of a person having both of those recessive traits is around 0.17%. Instead, most redheads have brown, hazel or green eyes, according to Medical Daily.
- The Redhead Days festival is the largest international event for natural redheads, but it was actually started by a blonde. The annual event in the Netherlands began when painter Bart Rouwenhorst put an ad in the newspaper for 15 redheads to model for him and more than 150 called. According to National Geographic, Rouwenhorst didn't want to turn anyone away so he got them all together so they could do a lottery to decide who would model, and that's how the festival started. Today it's grown into a massive three-day festival that attracts thousands from all around the world.
- Researchers believe redheads are more sensitive to pain because of a mutation in a gene (MC1R) that affects hair color. A 2004 study showed that redheads, on average, need about 20% more general anesthesia than people with dark hair or blonde color.
- A lot of redheads also wind up being left-handed. Researchers believe one explanation is that both of those characteristics are recessive traits and those often come in pairs
- Redheads actually have less hair and thicker strands than most people. On average, it’s believed that those with red hair have 90,000 strands, while blondes have around 110,000 and brunettes have 140,000
- Redheads are less likely to go grey. The pigment in red hair typically fades over time from red to blonde and white, but not grey.
- Despite plenty of debunked “studies” that pop up around the internet every few years, redheads are not going extinct.
- There are proportionately more redheads featured in commercials than there are in the world. A 2014 study found that 30% of ads during primetime hours included someone with red hair.
- Redheads produce more Vitamin D in a shorter amount of time than people with other hair colors.
- When it comes to skin cancer, redheads are at a higher risk than the rest of the population. A 2016 study found having red hair increased a person’s cancer risk as much as an extra 21 years of exposure to the sun.
- Being a man with red hair though could mean a lower risk for prostate cancer. A study from the British Journal of Cancer found men with naturally red hair were 54% less likely to develop prostate cancer, compared to other men with blonde, brown or black hair.
So here's to you redheads! We'll see you again in May for World Red Head Day.
