With this product of La Riche I'm not so happy :( I thought that a small amount sufficient to impart a tint pastel purplish to my bleached hair. That has ended, that in the end I had the whole box on his head. Even after an exposure time of 3 hours, take the hair the color not the same everywhere and look splotchy and for re-dyeing I would still have to chew another can ... I am now as an alternative a can of "violet" bought you I mix with conditioner / water :) Makes exactly the same tone, only that the can is not right yet! The shelf life of "lilac" is also not so good, but as I often change my hair color that bothers me very little!
