It depends on what shade of purple you want... If you want a dark purple I would recommend 'Schwarzkopf live colour xxl cyber purple' : My hair is this colour and I dyed it from medium brown. If you want a bright purple then I would recommend bleaching your hair then using 'manic panic ultra violet.
Using purple koolaid in your hair works and like other dyes will fade out quickly but for the price of a pkg of koolaid you can apply it as often as needed to keep the color in.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
