Reddish Brown

How long should I leave the dye in going from dark brown to reddish brown?
I have really really dark brown hair and i want to dye my hair reddish brown. The box says I should leave it in the 30 minutes, but should i leave it in longer since i have really dark hair?
Follow the package directions.
Obviously, red cannot cover over dark brown as well as it would over a lighter color but you will still see the change.
The directions should be followed so that you do not damage your hair.
