stumbled upon this girl's Instagram and it's literally my dream hair I've had in my head for years! how would I achieve this? and how would you stop the black bleeding into the blonde? how would you separate it?

i have 15 years experience dying my own and friends' hair but am by no means a hair dresser. is it doable at home? currently have split dye black and yellow. any advice is appreciated!! <3
