How do you keep your hair colour from fading?

so recently my hair dresser made a mistake and coloured my hair an orange colour instead of brown. since then i have been dying it darker brown each time, but every time i dye it, it keeps fading to an orangy brown colour..


so how am i supposed to prevent that from happening and keep my darker brown colour ?How do you keep your hair colour from fading?
get your hair professionally colored at a hair salon that knows what they're doing. also, if you want to do it at home, try doing it once a month, so you don't even see the orangey color. try getting hair colors that last a long time, too.How do you keep your hair colour from fading?
