The Guinness World Record for “longest arm hair (female)” has been formally held by a woman from California, as a strand of her arm hair measuring more than seven inches.
The record was set in December 2023 by Macie Davis-Southerland of Tracy, California, according to a release from Guinness World Records on January 18.
A strand measuring an incredible 18.40 centimeters, or 7.24 inches, was found on her right upper arm.
Davis-Southerland said her abnormally long arm hair was first spotted in 2012 by her friend’s brother.
“I was at Disneyland with my best friend Kaylee’s family when her brother pointed out a hair on my arm,” she told Guinness World Records.
Davis-Southerland refused to have the hair plucked by her friend’s brother.
She believed she might hold a Guinness World Record even back then.
Arm hair typically has a length of one centimeter, according to Guinness World Records. The majority of the hair on Davis-Southerland’s other arm is at normal length.
“None of my other arm hairs come even close to being as long,” she told Guinness World Records, adding, “They’re all a normal length for an arm hair.”
In the 11 years since the discovery of her super-long arm hair, it has grown over 15 centimeters multiple times, said Guinness World Records — but it either fell out or was accidentally pulled out before it could be measured and certified.
According to Davis-Southerland, it took multiple tries to get it measured for the world record before she was satisfied with the result, as she told Guinness World Records.
“I prematurely decided to go to my physician to have her measure the arm hair and gathered the evidence I could before potentially losing the arm hair and not having anything to submit once my application was approved,” she stated to Guinness.
The first measurement came out at 14.2 centimeters.
While that would still be the record, Davis-Southerland knew she had grown a longer hair in the past.
A month later, with the hair even longer, she got it re-measured. This time, it came in at 15.8 centimeters, but “the process felt rushed,” Davis-Southerland said.
“I couldn’t get all the evidence I needed,” she said.
Davis-Southerland found a doctor who was willing to measure her arm hair for the official record. Despite the unusual nature of her request, “not once did the doctor make me feel weird about what I was asking,” she said.
That time, her arm hair measured 18.4 centimeters, and was documented as the official record. Looking ahead, Davis-Southerland said she hopes to break her own record, as well as the record for “longest arm hair (male).”
With her new record secure, Davis-Southerland is also being less secretive about her abnormally long arm hair, and is telling more people about it, she said.
“My family and friends closest to me think it’s the most amazing and hilarious thing,” she told Guinness.
