He has one of the most famous manes in rock and roll history.
And the secret to Rod Stewart's iconic spiky hairstyle is none other than mayonnaise, with the hit-maker rubbing it into his tresses to keep them strong and healthy.
Rod, 76, is so fond of the unusual beauty hack that he even recommended Small Faces late frontman Steve Marriott give it a go.

Steve's former tour manager Elliot Saltzman has told The Sun how the guitarist - who died in 1991 at the age of 44 - revealed Rod inspired his own spiky hairstyle.
Explaining the method behind Steve's hairstyle, Elliot said: '[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.'

Rod is almost as renowned for his mop of spiky blond hair as he is for his raspy singing voice, and spends up to £6,000 a year on his famous mane.
Last year, MailOnline exclusively obtained photos of the star leaving a three-hour hair appointment at a luxury Mayfair salon.

Despite the lengthy visit, Rod left looking virtually the same.
It was previously reported that Sir Rod pays £340 a time to get a trim and a re-bleach every few weeks.
The music icon is said to receive the A-List treatment when he attends the salon and is served sandwiches on a silver platter.
A source previously said: 'Rod is quite pedantic about his locks. He gets high and lowlights put in every three weeks, and even if his hair doesn't really need doing he'll still come in to get it tweaked, either with a few strokes of colour or a tiny trim.'
Meanwhile, Rod revealed in March that his 'football days are over' after suffering an injury to his ankle.
Speaking to The Scottish Sun after appearing on crutches during wife Penny Lancaster's Lorraine interview in March, he said: 'My football days are over.
'I have a bad ankle injury which I suffered from being tackled by my 15-year-old son.
'I can still kick a ball when needed though.'

Rod has become known for his support for the Glasgow-based football club Celtic FC over the years.
He went under the knife last October just months after a successful knee replacement operation and still occasionally uses crutches.
Rod recently crashed 50-year-old Penny's Lorraine interview as she was discussing her police training and working to raise money for the British Heart Foundation.
Lorraine, 61, delightedly exclaimed: 'Hello! He's behind you', as Rod briefly appeared on screen while his wife was chatting.

Penny didn't appear to mind the interruption as she smiled as Rod walked off, before Lorraine quizzed her on why Rod was walking on crutches.
She said: 'Has he got a sore leg?'
Penny explained: 'He had knee surgery but the ankle surgery is taking a little bit longer to heal from, but he'll be back. He's got a whole new album coming out soon and he's very supportive of me doing the police, he knows I've got a burning desire.'
Penny and Rod have been married since 2007 and share sons Alistair, 15, and Aiden, 10.
