Redheads don't go gray
Unlike blondes and brunettes, redheads never develop gray hair as they age. A little-known fact about natural red hair is that it retains its original color longer than any other hair hue. Eventually, the ginger tends to turn blond, and ultimately white. On average, redheads have thicker hair, but fewer strands (about 90,000), compared to blondes (110,000) or brunettes (140,000).
The world’s highest rate of redheads is found in Scotland, where an estimated 13 percent of Scots—about 650,000 people—have flame-colored tresses, compared to 4 percent of Europeans and less than 2 percent of the global population,according to STV News. In the US, there are an estimated 6 million redheads.
redheads only make up about 4 percent of the U.S. population.

Interesting facts! So if redheads make up only 4 percent of the US population, why are there so many redheads in TV commercials. If you haven't notice, pay attention.

My favorite redhead was Maureen O'Hara. As a young lad my first crush was on Maureen O'Hara as Ezmerelda in "The Hunchback of Notre Dame" and that was in black and white. Years later she appeared in a John Wayne western in color - "McClintock!".
