Bleaching disaster - any advice appreciated!

Hi everyone 

I have previously bleached sections of my hair before, quite successfully and dyed over the top. I thought I would take the plunge and go for an all over bleach this time (it's 3 months since I last put any bleach on). Unfortunately, I don't think I got the mixture right and I had a much smaller amount of powder and peroxide than I thought I had. As it's Easter Sunday and I had a head full of coconut oil, I decided to crack on regardless. I thought I had covered all my head quite well, doing my roots last but I did notice that the mixture was quite powdery by the time I got to the end. I left it on for about 40 minutes as I could see some sections were going quite light and I daren't risk any longer.

Anyway, the result is awful. Some of my roots are a lovely light yellow, some of my hair is brown (barely touched by the bleach) and some of it is a few shades lighter but not exactly blonde. I have some bits that don't look to have been lifted at all.

I have bought Directions Fire to go over the top, so I was wondering how forgiving is it? And also, if I am really careful not to overlap, could I bleach the bits that look to have been missed altogether (coconut oiling again) or shouldn't I risk it? Would a bleach bath in a week be a better option, bearing in mind that I will have the Fire on by then.

I am really hoping that the Fire will look ok and I can worry about the missed bits another time but any advice at all is much appreciated!!

Thank you in advance
