You just have to arm yourself with some witty comebacks so you get a good chuckle from the look on their faces....
Some possible examples...
"Oh I had it coloured like this"
" oh I am just saving money - no more shampoo and conditioner - I did it so I could afford to buy a dress here"
Or if you're feeling a bit stronger -
" good thing I didn't ask your advice then"
" I suggest you think before you speak as you have no idea why I wear my hair this way"
I know it can be upsetting but people just don't engage their brain before they speak sometimes!!!
Mind you if you chose to wear your hair that way irrespective of BC it would still be offensive
