Query: Fades QUICKLY

I used this product for some highlights, and was expecting it to stay for several weeks. Not true... It lasted maybe 2 days before it faded into an ugly lavender shade. It was completely out by 5 days. Really dissappointing! So, if you never wash your hair, I guess it'd work. But for me, I'll just have to find a more permanent dye.
