so after having blonde highlights and a light base, I wanted to darken it just one level and cover up the roots, the hair colorist ended up giving me really dark hair, almost black, even he said "im surprised it came out that dark". I've been washing it everyday for the past 2 days, yesterday even 2 times, used head and shoulders as they say it can help remove the dark dye, i even used some baking soda and vitamin c (reading on the internet) no luck. He used an amonia free dye, not a permanent one, any idea? i dont want to re-color my hair just want it to fade out a bit. any suggections?
