Joshua Coombes is a hairdresser with a difference. While in his day job customers pay for their haircuts, in his spare time he trims fringes for the homeless free of charge.
He's a co-founder of the movement #DoSomethingForNothing, which asks people to give up their time to help others in need.
Using the hashtag, he posts pictures of those peoples hair he's cut to inspire others.
"It's about trying to incorporate this ethos into the week," he told Yasmeen Khan. "I've usually got [my equipment] with me, so when I see someone I just rock up.
"The look in the mirror afterwards is why I do this.
"It's great to see somebody smile, make somebody feel good. It might not change their world, but it might make them feel a bit better.
"We can all #DoSomethingForNothing and we can all get involved in this."
