As the UK's leading nail technician with a host of awards to his name – and celeb clients including the likes of Penelope Cruz and Kate Moss – Leighton Denny knows his polish specs. But before the glitz and glamour, Leighton was a forklift driver and after discovering the world of nail care on a trip to the USA, he decided he wanted to become the leader in the UK nail industry. Now, Leighton has his own salon in Harrods, heads up his gorgeous nail polish line and has won the prestigious Nail Technician of the Year award so many times they've banned him from entering and made him a judge instead. Talk about teacher's pet!
