Each of a tint with Directions is considering should know in advance that the colors are seldom more than a few weeks. The Turquoise looked at my hair bleached at the start great, with every hair wash (every 2-3 days), however, painted her blue water and the hair was a piece of green / pale, until the end, after several re-dyeing, the color had of dirty dishwater. Maybe the reason are my broken hair that it does not last as long. One should definitely before bleaching, because of my dark blonde approach the turquoise colored unfortunately no longer, so I dyed the whole thing after about four weeks. And in between, however, a very cool color and definitely something different!
