he cut it from very long to neck length in around 78? dont quote me on this. And then he got the "80's" cut in the (u guessed it) 80s because in all of the game videos (at least on QGVH1) he has it short
his first haircut was when he was three years old - his mother thought his long blond locks made him look a little too girlish
but if you're referring to his first -post queen haircut - it was 78 - the year he also had his first wooden teeth fitted, along with his colostomy bag and HRT implant
