Kiki Wigs

I need to dye my hair black because I'm Cosplay Kiki (Kiki's Delivery Service) in about 2 months (I want to be ready) and I need black hair for the look of being completed. I read all these comments about people not being able to remove the color, and I wondered if this was indeed the case ...
My hair is dull mousey-blonde, and it is the right length for Kiki, but I do not know if I should just use a dye or a wig?
Where can I find the right type of dye temporarily in the United Kingdom? Or, failing that, where can I get a short black wig from?

part of the color stays in your hair. I had my semi-permanent black hair is mousey blonde and my hair purple and gray and it does not come out correctly

you should get a wig

If your hair is already blonde it will take considerable time to remove the black with a semi-permanent hair dye and it will probably become purple after a while (my friend had this objective.) It would be preferable to use a wig if you do not want your hair black, purple, gray, and some other colors funny.

If your hair is light, it is a bad idea to use black dye semi-permanent. Perhaps the use of color gel.

which is one of my favorite movies!

hot topic.

If there is one out there? lol
