They say cool heads prevail, and more than 60 scalps were cooler than usual last night after volunteers were shorn to aid children with cancer. This is the second year the Hong Kong branch of the St Baldrick's Foundation, which raises money for child cancer research, has convinced people to go bald. Organiser Richard Kligler launched the charity drive in Hong Kong last year in honour of his son Sean, now 10, who at five was diagnosed with Rhabdomyosarcoma, a fast-growing malignant tumour that accounts for more than half the cases of soft tissue sarcoma in children. Among the volunteers were more than 20 under 12 years old - mostly from the Hong Kong International School, which Sean attends - who got a fresh new look for summer when they stepped up to the barber's chair. But former jockey and TV racing presenter Mark Richards went for a different look - he had his chest shaved. 'I didn't think the Jockey Club would appreciate it if I shaved my head so I shaved my chest instead. It was very hairy,' he said. Even before last night's donations at the Dublin Jack pub in Lan Kwai Fong were tallied, St Baldrick's had raised more than HK$562,000 online. 'All we're missing is a woman to have her head shaved - that would break the barrier,' Mr Kligler said. St Baldrick's Day started in New York on March 17, 2000, when a group of reinsurance executives with Irish roots decided that instead of downing pints of Guinness on St Patrick's Day, they would be sponsored to have their heads shaved in solidarity with children who had lost their hair to chemotherapy while undergoing cancer treatment. Since then, St Baldrick's volunteers have raised more than US$20 million at hundreds of fund-raisers and head-shavings worldwide. All funds raised locally will go to Hong Kong Children's Cancer Foundation.
