Can I dye my hair over semi-permanent color?
Yes I think you can, if you don't like the semi-permanent color, but its best to just leave it so that the semi perm can just wash out. Then when its practically all gone and you can only see a hint of it- then i would suggest dying your hair permanent or go to the hair-dresser's. x
as a matter of fact you can dye your hair over semi permanat color.
