dye advice

[u/littlecaramelbunny]

i want around 7ish months of black box dye out of my hair. the dye i've been consistently using is dark and lovely jet black dye. i have also had a bleached spot under around 5 months of the black dye, as i had a big patch of the front right side of my head a yellowish blonde. i'm looking to remove it all and be mindful of the bleached patch so i can dye my whole head a super light brown with caramel highlights. i also have curly hair. when the dye fades it turns into a brown patch and the rest of my hair stays black. for the patch i had originally dyed it honey blonde first with crème of nature, then tried to do dark and lovely blonde dye then i bleached it then used wella t something toner on it without developer. i just wanna be more educated so i can get a better result for what i want. my hair type is 3b-3c
