I once met a chap in prison who had cut the hair of some of the Liverpool football team. (This was years ago though) He said they were incredibly vain and fussy, because they were on view on the TV and the supporters noticed every detail. I think the man was telling the truth because some of the other inmates knew him and verified his 'claim to fame'. He also cut the hair of many of the other prisoners 'inside'. Also, don't footballers nowadays do modelling of kit etc for brochures? If so, they'd need to look ultra-fashionable and smart.
