What is the best hair dye?!?

L'Oreal Feria is the best drugstore hair dye that I've seen. My suggestion is to bleach your hair once and use Manic Panic dye in Vampire Red. http://www.amazon.com/Manic-Panic-Semi-Permanent-Hair-Vampire/dp/B0010O0E0Q Any hair dye, especially in red, will fade but with this dye you don't have to worry about overprocessing your hair too much since its semi-permanent. They come out very very vibrant.
