How fast does henna fade?

I've been wanting to dye my hair red for a while, and I think I'm going to go with henna regardless because peroxide does a number on my hair. That said, does it tend to last longer, shorter, or about the same as regular hair dye?

Keep in mind this is Body Art Quality henna I am talking about. BAQ henna is the only henna you should use on your hair.
