v3nu5 - Thanks!! And I would try just colouring over it! This purple is really blueish, and looks royal blue under fluorescent lighting. I think if you have hot pink in your hair right now, it might make it a true purple.
loserchick88 - thanks so much!
dropoffradar - Thanks! I think you should go for some colour!
You could try going red first, since it's more of a natural shade?
