Antony's son, Peter, wrote to CBBC Newsround Online all the way from India, to say how chuffed his family was with the record.
He also told us that his dad used to be a head teacher at a school, where all the pupils and staff called him 'the ear-haired teacher'.
A third challenger
Antony has smashed the record held by B D Tyagi from Bhopal, India, whose ear hair is just 10.2cm long.
But he may have to hang on tight to his hairy record.
A third man, Narayan Prasad Pal, also from India, is claiming his hair measures a whopping 13cm. But that's not been confirmed yet by the Guinness Book of Records.
