Suddenly it all fades overnight

Hi Everyone,

I wonder if anyone recognises this problem. I've used these semi permanent dye since the last millennium and once started with Fudge, use mostly Directions but also sometimes Manic Panic, Stargazer, Crazy Color, whatever crosses my path. I'v always used shades of red and pink. Now last year I had a blue phase that lasted almost a year 'till my boss made me wear a wig and I got tired of that. So I went to a hairdresser to hurry back to red. She bleached out the blue and did an excellent job, but.. ever since (october) no colour will stick. It just fades overnight, without me even washing my hair. I've tried all the above mentoined brands but no luck. So now I've got this faded pink color all the time (not even a pretty pastel, just the ugly washed-out color without even washing). Does anyone know what to do? Another brand to try? It's becoming really expensive and depressing to use two boxes a week without result..
