hehe when i started going to the gym everyone stared because i was so hugely fat and i THINK i had orange and yellow hair at the time (though it may have been pink).
Anyway its been purple, blue, green, combinations etc all the way through. Then after about 9 months i started cycling and went to a personal trainer. So for old times sake another 6 months or so later i went back to the gym. Funnily enough a lot of the old regulars came up and congratulated me on the weight loss, they only way they regonized me was apparently the hair
