OK, I know this is hormones and probably not a good idea, but I'm going to do it anyway so please help me make it the least bad idea it can be!
I am being induced tomorrow at 40 weeks and my hair is a mess.
I know it doesn't matter in the grand scheme of things, but right now it seems like a really big deal that my hair looks awful and I have to dye it.
I have to stay in today for a courier to pick up a parcel so can't get to a hairdresser or shops.
I have one box of superdrug permanent blonde hair dye I can use but cant decide how to use it.
I used to dye my hair all over but it was getting very brassy (as my natural hair colour got darker, it didn't seem to take it all the way to blonde any more, iyswim) so I then decided to let it grow out and just use a light brown dye on the roots to cover the bits of grey...but the ends are still very blonde so now I have brown on top and blonde through the lengths from ear lobes down which looks horrid. Plus the brown doesn't really suit me.
Should I
a) put the blonde dye on all over and leave it on for half an hour (what I used to do- meant the roots were less blonde and more orange than the lengths that had repeat dyeing but was simple and easy to do)
b) put the blonde dye on roots only and then try and spread it through for a bit but then how to match up the bits and will this just leave me with orangey roots rather than brown and blonde ends???
c) I have found (at the bottom of the clothes hamper 
one of those old plastic caps with little holes in that you used to use to highlight hair- I could pull strands through and just dye those- would this look more natural and blend the top in with the bottom better without looking all over brassy or would I just end up with weird blonde strands and still two tone hair??
Help!
