With a $1 million insurance policy, Polamalu's hair makes more money than most of his teammates.

Pittsburgh Steelers fans can rest easy knowing that Troy Polamalu has taken out a $1 million insurance plan. Not on his physical health, of course. And not for the professional security of the Pittsburgh football team. The insurance plan is for his hair. That way, he can keep making those Head & Shoulders commercials.

The shampoo company took out the $1 million dollar plan with insurers Lloyd's of London, just in case the Pittsburgh safety's flowing main falls prey to one too many flags on the play. Here are some other professional athletes who might want to take out insurance policies of their own.

Tim Lincecum

The Franchise takes pride in the cap he wears on his head to the point of always wearing the same cap. Official New Era on-field caps currently retail for $33.99, but Lincecum might want to take out a policy for considerably more money than that. After all, a cap worn for not just one, but two Cy Young Award seasons probably has enough sentimental value to fill in the entire San Francisco Bay.

Joel Zumaya

When you care enough about a video game to jeopardize your professional baseball career, well that's love. The Motor City right-hander throws fastballs faster than a Detroit muscle car, but his arm is no match for Rock Band. It might be worth his while to take out an insurance claim or two on his play guitar. Never mind that the game's Gibson SG custom is made out of plastic and doesn't even have a fretboard.

Chris Johnson

Let's hope the Tennessee Titans have a good dental insurance policy with a low deductible. Chris Johnson's gold grill is probably worth more than season tickets at LP Field. If the Titans don't have a generous benefit package for their employees, their star running back may want to take out a Lloyd's of London insurance policy of his own. And don't forget the metal polish toothpaste.
