Removing semi-permanent hair color
I've been using L'Oreal Castings in medium brown for years, Gradually the ends of my hair have gotten too dark so I'd like to "pull" some of the color out. (repeated washing has not faded it at all)
I've tried the Clairol UnColor product and also the Metalex method. Neither has done much to remove the old color.
Supposedly, the color removers for permanent haircoloring don't work on semi-permanent products (Something to do with the difference in the dyes ?)
Does anyone out there know of another way of pulling the old color ?
