Consult a hair stylist you trust.
Yes you can.
If it is temporary hair dye, the color should wash out after awhile. If it is permanent, your natural hair color will come back as the roots grow out, which could take awhile.
You'll never get it back to the natural color by dying it.. Natural literally means 'existing in or derived from nature; not made or caused by humankind'.The best thing to do is wait for the dyed color to fade away.
Until your natural hair color starts showing back. You will probably need your roots touched up like every 4 weeks, and go back to get it highlighted like every 6 weeks or so, depending on your hair type.
welll it should eventually grow back but it takes a LONG time ...
Grow it out.
Dye it back to your natural color
Only dye your hair back to it's natural hair color if you're irritated of dying your roots every 3-4 weeks.
You should bleach it first. Well, it really depends on what color you want it, but usually you bleach it. I don't recommend bleaching black hair though, because bleach damages black hair more than any other color. You may never get it back to your natural color.
Engage the services of a skilled hair colorist who can determine your natural hair color and then adjust your current color. As your natural color grows out, the line between the color and your natural hair won't be as noticeable.
grow out the dyed hair until you see your natural color. wait until it gets long enough, and then cut it.
they kind of do but yah they look more like your natural hair color
