If you dye your hair purple (semi-permanent) directly from a natural reddish-brown colour (no prior bleaching), how long does it take for the hair colour to completely return to its natural colour?
Answer on How long does it take for purple hair dye to fade (please help!)?
probably a week or abit longer it will depend on how much you wash and what type of shampoo and conditioner you use :)
if you washed it every second day (unless your hair gets greasy after one day) and use colour portection shampoo it should last a good 2 or 3 weeks :D depends on the dye and stuff :)
