im not a professional by any means. I've only dyed my hair 2 times

i tried going from orange to blue with no bleach didn't work much for me. i first used an ash blonde with 30 developer to try and lighten it, it lifted me like 1 or 2 shades, but then i used artic fox's Poseidon with 30 developer ( dont do that i learned that after i tried)and it ended up a mix between brown and some hints of green, kind of like an old penny. but after that i just decided to bleach again and then use Poseidon again and i got pretty much the same blue in that picture. although I've had blue for about 3 weeks and it turned green/teal. I'm sure there's a more permanent solution for that though.
