I previously dyed my hair jet black and had the roots showing, it look like bad. the tips were jet black and the roots were brown. it was very visible so, I decided to dye back to brown or so color close to the root color. Today, I dyed my hair medium brown (which I though it closely match my natural hair color). I dyed and the tips are brown and the color the box said, but the tips are yellowish/ orangy. Similar to the color or yams. I don't know ... was my natural hair color lighter than brown, that's why the brown dye fucked up the roots and can I dye my hair again tomorrow ( dark brown). Please help ....
