It’s Friday night at St Columba’s Church in London’s Knightsbridge. Helen joins Haircuts4Homeless founder Stewart Roberts at work and chats to some of those who turn up for a free cut and warm meal.

Stewart started offering homeless people haircuts eight years ago. He now has 600 volunteers who have given more than 40,000 cuts all over the UK and Ireland, and the charity is proud that Game of Thrones star Lena Headey is an ambassador.

Hear Me, See Me - a beautiful book of black and white portraits of Haircuts4Homeless guests shot by Jack Eames – is on sale to help raise funds so the work can continue. Stewart says: “It might be ‘just a haircut’ but it’s the kindness shown that makes a homeless person know people care.”
