Is "Natural blond and red hair are going extinct in the global population" true?
Every so often, a headline announces that blond or red hair will vanish from the human race within a couple hundred years, usually attributed to some unnamed study nobody can quite locate. It's alarming in exactly the way that guarantees it gets shared. Recessive genes don't actually work like an endangered species heading toward zero, though. They sit quietly in carriers, generation after generation, ready to resurface whenever two carriers happen to have a kid together. Extinction was never really on the table.

Natural blond and red hair are going extinct in the global population
What we know now
Hair color is controlled by recessive genes that can persist hidden in carriers for generations. Population genetics does not support claims that blond or red hair is disappearing from humanity.
Was "Natural blond and red hair are going extinct in the global population" taught in school?
Yes — and not as a joke question on a quiz. This science claim showed up in textbooks, worksheets, and classroom posters through the 1990s, which is why so many people still remember it as settled fact long after the science moved on.
Is "Natural blond and red hair are going extinct in the global population" true?
No. Hair color is controlled by recessive genes that can persist hidden in carriers for generations. Population genetics does not support claims that blond or red hair is disappearing from humanity. If you want the primary citation, start with Nature - Blond Hair Is Not Going Extinct.
When was this understanding updated?
The evidence had largely shifted by around 2007. Schools don't flip overnight, though — plenty of classrooms kept teaching the older version for years after researchers had already moved on.
