Hahaha Vi - I have been admiring a girl in a hijab today - very fashionable suddenly in liverpool, a hijab, full face of make-up (arabic style) and a short skirt with opeque tights, yes, thats right...go figure, she was clearly showing off her new pins post CD and covering up the fact that she was a tad sparse up top.
It happened to me the first time round which GUTTED me as my wig is my crowning glory, BUT it comes back with vengence. Lily (as usual) speaks the truth, the hair is beyond salvage as in a VLCD your body goes into a sort of shock and stops feeding the non essential bits of your bod, so hair is the first to get it, followed by nails, followed by teeth obviously it takes a long time, but I have heard of people getting into teeth trouble while on a VCLD before. Several on here in fact...anyway thats only for those people who just continue on the diets themselves I think, and who lose a lot of weight and dont take care of the calciummy.
You will be fine and your lush bonce wont need a lace wig - dont sweat it. That said, start wearing your hijab around town, it's worth it just for the kudos.
