My hair is a natural medium ash brown. I have white and silver roots. I used the Harvest Moon brown but my roots are a copper color. Since my hair is short, even though I applied to roots only, the majority of my hair is brown but a little lighter than I prefer. If I use the Earth Brand Ash Brown, will I get a natural Ash brown all over with gold highlights from the white roots? If I'm trying to avoid a two tone look, should I go do a different brown?
