I just used L'Oreal Les Blondissimes Platinum on my hair. Big big mistake. I usually use Light Ash Blonde shades - mostly L'Oreal - and they're fine but oh my fucksy! This. This has come out psychadelic sunshine yellow with shades of ectoplasmic dayglo vomit and I am not joking. I'm in shock and don't know whether to laugh or cry!
I need to get this fixed today - NOW - and I'm begging advice on what colour to put on top of this to fix it.
No I cannot post a picture. I can't even look at myself in the mirror. You'll have to trust me - it's unbelievably fucking awful 
Help please!
