I have naturally red hair, but have been golden blond for about a year, I bought a dark reddish brown color yesterday, and the color came out dark redish purple, it looks awful. How do I fix this, get rid of the purple?

My problem is always getting the purple to stay. I try to go for reddish purple and the purple fades out quickly and I'm left with red. You could try that shampoo, I think prell? And see if it'll fade quickly.
