What is the best, perminant, bright, red hair dye??

I need super stay bright red hair dye, if I'm gonna do it I want to do it well!!What is the best, perminant, bright, red hair dye??
If you want boxed color, I would try Feria. I always had good luck with that. However, reds always fade fast no matter if you get it done professionally or do it yourself. It's just the nature of the color. If you get it done professionally, I like both the Chi and the Redken lines.





Edit: ooO also the John Frieda Red Color GLAZE. It is almost like a professional tint. This stuff is AMAZING! My hairstylist friend even said she said it is one of the coolest tint products that she has seen, especially for non-professional brands. Basically every time (or every other) you wash your hair and condition it, use the glaze and you are pretty much re-tinting your hair over again. It does stain the scalp slightly, so be careful with the part. Greatest thing ever though.
