Light Mountain Henna Help With Henna Hair Dye!?!?

Help with henna hair dye!?!? - light mountain henna

My hair is medium brown with some blond highlights ears down the hair ends (just under my breasts.) I want my hair to a medium brown. As a color that can be considered red, but still brown. It is bright red / orange! I know you do not get many opportunities, with henna hair, what should I do? When I add use pure henna, which I have enabled it and how long should I go? If I is the light mountain henna hair dye use "brown" right color? Or is it just coffee? Please help! Thank you:)
