American football player Troy Polamalu's hair insured for $1 million

American football star Troy Polamalu has a price on his head -- with an anti-dandruff shampoo brand taking out a $1 million insurance policy on his trademark mane of black ringlets. 

Head & Shoulders said on Monday it had taken a $1 million Lloyd's of London policy on the locks of Pittsburgh Steelers'' Polamalu, the Super Bowl-winning safety.    

Polamalu, 29, who was born in the United States but is of Samoan descent, says he has not cut his year since 2000. He has been a spokesman for the Procter & Gamble Co brand for two years. 

"They''ve created the first ever insurance policy to protect his iconic mane for the entire NFL season," Procter & Gamble said in a statement.

Polamalu, a five-times Pro Bowl selection, suffered some injuries last year but is back in the game and expected to be the backbone of his side's defense this season. 

His hair has come under attack on the field before, with Larry Johnson of the Chiefs tackling Polamalu by the hair in a 2006 game, but no details were given of exactly what damage to his hair would trigger a claim on the insurance policy.
