Rod Stewart has always been known for his spiked hair, and apparently the secret to how he gets it is now out. The secret was revealed by tour manager Elliot Saltzman, who claims he found out from Small Faces frontman Steve Marriott, who had copied it from Rod. According to Elliot, Steve said the “spiked up rooster hair” was the result of “putting mayonnaise on his hair and rubbing a towel on his head really fast.” And apparently experts agree that mayo can be good for your locks, with one saying “It contains proteins that will make hair strong and prevent it from breaking.” So if you want Rod's signature look, mayo is the way to go. I don't know if I'm willing to go that far for my hair, but to each their own. And it certainly works for Rod! Would you try it?
