Girls hair dye stuff

[petemc]

My girlfriend likes to dye her hair. It's her birthday soon and I wanted to get her some funky colours and an easy hair dye kit. She's borrowed some bowl and application tool from a friend a couple of times, but I dunno what that was.

Is there some sort of shampoo or gun or magic pixie dust that I can buy to make her hair go super cool whenever she wants?

For example;



She likes that colour, reds and purples etc. I've tried looking on Boots site but they only seem to have generic blonde, brunette, etc.
