Ok, about six weeks ago I had what can only be described as a sudden rush of blood to the head - and went and had my dark brown hair dyed blonde. Please don't ask why, I've asked myself this since and drawn a blank.
It really is absolutely awful looking - think yellow and orange stripes and, worse, the inevitable start of root regrowth. I really didn't think this through properly, as I can't afford to maintain it by going for root touch ups etc. It cost me an arm and a leg to get it done in the first place, but I considered it a 'treat' to myself as I'm approaching 40 and wanted to give myself a bit of an image makeover. I seriously can't afford to get it dyed back to its original colour, so am feeling a bit stuck.
I've got a close friend's wedding to go to a week on Saturday but, tbh, this bad do is making me dread going out the house.
What are my options here? I've (almost seriously) considered an all-over number 4, and starting again. It's tempting!
What would happen if I were to dye it at home? Is six weeks too soon to try? And do I run the risk of it going green, or baby pink?
I knew it was time for action when ds(4) said to me this morning that my hair was "all lovely and yellow with brown stripy bits" 
Please help!
