If you use permanent blond hair dye will it make your hair blond?

The purpose of permanent blond hair dye is to change your hair color to a blond color, but it depends on what your original hair color is on how effective it is. If it is dark enough, it may be necessary to do multiple colorings or bleach your hair before dying it. If you plan on just trying to lighten your hair color, I suggest using a hair dye that's only a shade lighter than your desired color.
