Is there any way I can make my hair darker without dye?

i used John frieda Go Blonder shampoo for about 3 weeks in hopes to make my hair lighter. I'm not sure why, but it made my hair about 5 shades darker than it is naturally. I really want it back to normal (medium- light brown). Are there any color depositing shampoos or something thats not dye that i could do/ use to make it darker? (it also has a brassy tone in it now, if anyone knows something i could do about that, that'd be great!) Thank you so much!
