Hey Tigress!
Loreal also makes a product called "Color Pulse", and there are a couple of purple tints in the line: Funky Purple & Chill Plum. It is actually a mousse - so it might take some playing with to do highlights, but it is only a temporary color (washes out in 8- 12 shampoos).
I used the Chill Plum, but since my hair is actually a dark blonde it lasted a lot longer on my hair (whoops!)

Here's the link to their site:
Loreal Color Pulse Hope this helps!
(Oh, BTW - just so you're not scared - the bald is NOT from the hair color - LOL!)
