Tonight Arena takes you on a tour of contemporary British heads, from the exotic to the mundane, from hot wax to Brylcreem. Blue rinse, quiff, mohican, short back and sides, dreadlocks or just shaved off altogether. By your choice of hairstyle you tell the world about yourself. You can blend in with the crowd or stand out from it. For some it is a fundamental part of their religious beliefs, for others pure indulgence. What are the prospects for a bank clerk with a hennaed 'trojan'? How does a white man become a Rasta? Does the back of your neck still prickle at the thought of the barber's clippers? This Arena investigation will make your hair stand on end.
