Towards the end of last year, I received an email from a PR Agency. Would I be interested in interviewing Shane Warne about the hair transplant technology he supports? Of course, I replied. Chatting to his assistant before she handed me over to Shane, she asked me what kind of feature I hoped to put together about hair loss. I burbled something about wondering why sportsmen so often seem to be involved in hair loss treatment ventures – Michael Vaughan and Ryan Giggs, for example. Are sportsmen less happy with going bald than mere mortals? Is it a vanity thing? Or a fame thing? But in truth, I didn’t give two hoots about the hair loss thing. I just wanted to speak to Shane Warne.
