The Black Sabbath star's daughter, who is known for her vibrant hair colour choices, is an unlikely fan of Ozzy's natural grey shade and has urged him to keep it.
Speaking to U.K. newspaper Metro, Kelly said: "I'm trying to talk him into keeping the hair... My dad's grey hair is the most beautiful colour grey hair I have ever seen and I pray that I have that colour."
"I keep going over and touching it because it feels like silk and it's so thick and gorgeous," she explained. "Because of his Parkinson's he can't dye it until the pandemic has got to a better place – since he's so high risk, but he's counting the days until he can dye it again."
She added: "I'm trying to talk him into not dyeing it."
Ozzy went public with his Parkinson's battle back in January after being diagnosed with the disease in February, 2019. Despite suffering with the illness, he's determined to return to the stage once the COVID-19 pandemic passes to complete his previously-planned tour dates.
