Sadly that numpty is me 
My hair is naturally dark brown. I normally put a semi permanent dark chocolatey colour (Casting Gloss) on it but I fancied a change and used a bright berry red instead. Love it! But it fades so quickly :( My eye has caught the Schwartzkopf Live colours and they look amazing but they're permanent.
Soooo, my question is, if I put a permanent bright red on it, how hard would it be to get back to my dark brown when I get bored of it? Would it simply mean putting permanent dark brown dye over the top?
Thanks in advance :)
