Matt Le Blanc used to dye his hair when he was on 'Friends'.

The 50-year-old actor has admitted he noticed the signs of ageing during the second season of the popular American sitcom, which last aired in 2004, but he was keen to colour his locks to avoid grey hairs from showing through.

Speaking on 'The Late Late Show with James Corden', the star - who was known for playing the role of Joey Tribbiani in the NBC programme - he said: ''I started getting grey hair on the sides, and they started dying it.

''Finally, I said to the hair guy, 'You know, I was in the supermarket the other day, and they have this stuff called Just for Men, it [takes] five minutes. Is it the same stuff? Because it takes you two hours and can I do it with this stuff, five minutes at my house.''

''[The hairstylist replied] 'It's the same stuff.'''

Matt decided to try out the hair product, but suffered a slight mishap as his ears ended up being tinted black.

He explained: ''Cut to me in the shower, shampooing and the next day my ears are all black.''

But Matt decided to ditch the beauty product to embrace being a silver fox.

Asked why he stopped dying his hair, he simply said: ''I couldn't be bothered anymore.''

Meanwhile, Matt has revealed he is ready to enter early retirement now he has reached the milestone, because he would love nothing more than to sit back and not do a ''f***ing thing''.

Speaking previously, he said: ''I would love that. I would like to retire earlier than later, because I think I would like to do not a f***ing thing. That's what I would like to do. Just nothing. Nothing! Zero.

''On a typical day, you would sleep as long as you want ... or get up early, if you want. It's just not having to go somewhere, or someone else telling you what you have to do. Maybe you go to the gym, or not go to the gym. Maybe you have nine cups of coffee, or none.''
