I agree Petra i'm sure they can afford the best of what is out there, but maybe they don't care ,Gloria Hunnifords husband is a hairdresser so you would think he would have some knowledge about this problem,
Although some people swear by Biotin, and i must say what hair i have that is ok, has grown like weeds,i have cut it 3 times now and it seems to grow overnight
Some kinds of hairloss will never grow back, and that the does will probably do anyway, but takes time
I have got every vitamin going i think that is recommended, got some viviscal now but it's very expensive, and extra vitamins might help, but only if it's going to grow back anyway maybe
