John Frieda Sheer Blonde

I have sixty per cent grey hair. I used a John Frieda 'blonde' shade (can't remember which one and I've thrown box out). The resultant colour is a weird shade of pinkish-grey pearl which looks totally unnatural and reminds me of old ladies' tights. The packet showed a lovely yellowish blonde colour and I am extremely disappointed. It is very hard nowadays to get a proper yellow/dirty blonde shade that comes out true. My own grey was much better than this!
