Will Loreal Feria Spicy Red turn my mousy brown hair Fire engine red?

Feria is pretty strong so I'm confident it will turn your hair that color, mousy brown (the lighter the better) dyes very well with almost any color. just make sure to get 2 boxes if you hair is long or thick. The bad thing about red hair color is it fades pretty quickly, so after a week your hair wont be so crazy bright red.
