i highly, highly suggest using a lightener like L'Oreal Platinium. it makes a world of difference. the texture is perfect and its creamier consistency doesn't dry out as quickly like regular powder lighteners. i think balayage gets a bad rep from stylists who don't properly modify their bleach mixture/application to compensate for the open air aspect of balayage - and u end up with a brassy, sloppy mess.
also, always remember to drop the product off on the mid-shaft and feather it up making the application finer and finer towards the root.
