Rod Stewart’s Secret to His Iconic Hair? Mayonnaise

Rod Stewart has one of the most iconic heads of hair in music history, and reportedly, it's thanks to mayonnaise.

This fun fact comes courtesy of Elliot Saltzman, the former tour manager for the late Small Faces frontman Steve Marriott. Saltzman told U.K.'s The Sun (as transcribed by Daily Mail) that Marriott would style his hair by "...putting mayonnaise on his hair and rubbing a towel on his head really fast. And he said he got this from Rod Stewart."

While mayonnaise seems like a weird thing to put in your hair, considering the popular condiment is made from emulsified oil and egg yolks it actually doubles as a conditioning treatment for hair. In fact, a mayonnaise hair mask can even help reduce frizziness and potentially help with hair growth.
