Bon Jovi has blamed his excessive use of hairspray during his band's 80's heyday for the hole in the ozone layer.
The star reveals his desire for dedicating large portions of his time - and money - to green charities could have something to do with his 80's excesses, he reveals.
"Do you really want to know why I'm doing all this goodwill, and why I'm an ambassador for Habitat for Humanity and why I gave a million to (Hurricane) Katrina?," he says, tongue-in-cheek.
"It's because I feel guilty about the huge hole in the ozone layer my haircuts created. It's my responsibility to right the wrongs of the Eighties.
The rocker has been particularly active in recent years, donating $1m to Oprah Winfrey's Angel Network foundation in 2005, as well as working on behalf of the Special Olympics, the American Red Cross, the Elizabeth Glaser Pediatric AIDS Foundation and Habitat for Humanity.
