Hair dye that actually lasts 2 weeks?

try using a permanent one, its worth a shot, its what i use everymonth from going shades lighter and darker,

i love garnier products, also make sure you use the after conditionar stuff and try to get a shampoo and cond for color

it helps keep it in your hair
