Approaching 40- have gone from near waist length to a bob in the last six months and feel further funkification is required as bob makes me feel frumpy... this is a hair trend started of course by youngsters without a grey in sight who love it cos they don't have to worry about roots - and of course I do worry about roots, in addition I have got my sad ole locks 'hairdresser ready' by leaving on a John Freida foam dye for too long and am almost black haired now... any thoughts, anyone had it done?
