Blonde hair actually is full of secrets. Recently, a study out of Stanford University–probably conducted by some smartypants blondes–showed that a switch in a single chromosome creates lighter hair. Yes, blonde hair is genetic, but it’s only “skin deep.” An A (adenine) changes to a G (guanine) on the twelfth human chromosome, which is the same chromosome that makes an animal a mammal.
According to Forbes, “the team says that because this specific genetic change only affects the hair follicle, other cell types are not affected.” So, being a blonde doesn’t have an impact on any other cell types in your body–including your brain cells.
The study also revealed that the genetic code behind hair color cannot be linked to other traits, such as skin or eye color. Even though blondes often find themselves at the center of jokes, there’s no scientific proof behind dumb blonde jokes.
DUH. Let me refresh everyone at Stanford University’s memory and roll out a list of fabulously smart blondes.
- Betty White: She’s blonde and funny–a true blingle.
- Cleopatra: Some rumors say she was blonde, even though that doesn’t make any historical sense.
- Elle Woods: She got into Harvard. What, like it’s hard?
- Madonna Louise Ciccone: She moved to New York City in 1977 and has rocked ever since.
- Ivanka Trump: She’s a successful businesswoman and a former model.
- Margaret Thatcher: Some say her hair got lighter as she became more powerful.
- Marissa Mayer: She’s the president and CEO of Yahoo.
- Shakira: She has an IQ of 140 and she speaks four languages.
So, thanks for the proof, Standford, but oodles of blondes have been proving that golden locks mean you can rock the world and look fabulous at the same time. Smart and pretty, people.
