That really isn't a good idea. The bleaching process leaves hair damaged and weakened and frail. If you add another chemical process to it you risk frying it and making it feel stiff and brittle, it could even fall out. If you are having trouble getting colour to take on your particular hair because of colour or texture, you should consult a stylist or hair colour specialist. They can give you some ideas of ways to make the colour come out the way you want it to without ruining your hair.
