Rod Stewart apparently shared the secret to his iconic spiky hairstyle with Small Faces' late frontman Steve Marriott – a deeply nourishing mayonnaise hair mask.

The rocker, 76, is known for his iconic barnet and, according to Steve's former tour manager Elliot Saltzman, he imparted his hairdressing wisdom with the hitmaker prior to his death in 1991.

Elliot tells The Sun newspaper of Steve's own hair: "(It) was created by putting mayonnaise on his hair and rubbing a towel on his head really fast. And he said he got this from Rod Stewart.'

The oily condiment has long been used as a DIY hair mask as it's packed with nourishing properties. Rod has yet to confirm his apparent beauty secret.
