Hair Dye Answers

Here’s the scoop: I am an idiot. I jumped the gun & decided to add some highlights to my dark blonde roots to blend better with the rest of my blonde hair. I only did a few & they ended up turning into peachy blobs on my head after the max 45 mins. It didn’t actually look THAT bad & was fixable. Then I got a really really stupid idea & got boxed golden brown dye. I thought I could just go over the peachy blobs & get it back to how it looked in the begining.
It ended up turning my roots a hideous coppery warm color & the rest of my hair completely ashy & DISGUSTING.
(I decided to just cover my whole head instead of the peachy colored blobs).
Needless to say I started scrubbing & washing my hair immediately after I did the initial rinse. I’ve washed my hair 10 times already today.
I looked at the box & another mistake is that it was permanent but amonia free.
Here’s my question, will Amonia free permanent hair dye fade faster then if it had Amonia in it??

i have to find a hair dye without bleach, does that mean without the ammonia?

I saw an ammonia free hair color in an organic food store the other day. Would it be better for the hair to use such a product, as opposed to a chemical one…why?
Would the color still take well?
