Dying hair over old hair dye?

Question

i dyed my naturally dark brown hair a darkish auburn colour about 3 months ago, and then did my roots again about a months ago, but now i want to go darker again. Is it safe to dye my hair darker is its already dyed? I'm going to get an all over colour professionally, not do it myself...just wondering if its ok to dye it after i already have?

Answer 1

yes it is perfectly fine as long as it is a week after you dyed your hair last.
