I have naturally grey hair. A few months ago I started dyeing it purple with Manic Panic temporary dye.
The dye has lasted way way longer than I expected it to and has now started to build up a bit (I've been dyeing whole head when roots needed doing) and I'd like to make it lighter so I can dye a different colour.
Would Colour B4 take some of the colour out without making me go orange or any other weird shade? And is it damaging?
