Okay so i had my hair "professionally" done in china about a week ago and it turned out orange and uneven. so the day i had it done was a medium brown, after i spent a day in the sun the top 3 or 4 inches of my hair turned light orange brown while the bottom remained dark brown??!

i think i'm partly to blame too becuase before that i tried an at home haircolor (nice n easy, reddish brown made for dark hair) but it do anything at all so i didn't think anything of it.

i'm thinking about apply a semi perminant color (like natural instincts dark auburn brown) but i don't want any unexpect results. what should i do?

(my natural hair is thick black asian hair)

I would go to a speialist colour correcting salon. The more you wash the more orange will be noticable as the top lyers of colour fade. Go pro and save yourself  unwanted results.
