Can i re-dye my hair that i have just dyed today?
as long as none of your hair is currently bleached then you can colour your hair with the black dye whenever you wish to. hair is not alive, it doesn’t recieve a blood supply like the rest of our bodies so once it has left the scalp it is classed as dead so any damage done to it cannot be “repaired” as some people like to think so in other words it won’t matter whether you re-colour today or next week, the effect will still be the same on your hair.
