When it comes to hair, some people go by the mantra, "Shut up, it's just hair." Which is, quite honestly, a pretty fair point. It is just hair.
Most people have it. Plenty of animals have it. Even insects have hair.
It's not like it takes any special powers to grow it or anything (don't tell that to LeBron). It just exists in various lengths, colors and portions on the heads of most of the population. Unless you have the balls to Bic it, even balding people have some remnants.
So what's the big deal then? Well, as mundane as the general existence of hair may be, there's no denying it has the power to make an impression—and a lasting one at that.
If it was "just hair," people wouldn't still be talking about the great mullets, mustaches and memorable hairstyles of athletes from decades past. For some people it's just hair, while for others it's their chief physically defining attribute.
People in sports can make their hair famous, or their hair can make them famous. Sometimes it's a combination of both.
Here are some of the most famous hairdos in sports, past and present.
