Directions Semi Permanent Hair Dye are non-damaging, easy to use, hair colorants that will leave you with hair others will talk about. Simply pick a colour that fits your mood and Directions dye will do the rest. All the 34 colours can be mixed with each other meaning the possibilities are endless, and if you're not brave enough to go bold and bright all over, try adding subtle highlights of a bright colour to turn heads instead. It is worth noting that for best results; use on light or bleached hair (may give sheen to darker hair.) As the hair dye is semi permanent, colours will gradually fade and wash out in 2-6 weeks.
