I have just dyed my hair with a bleaching kit and it has gone a terrible shade of ginger in some parts. My hair colour is naturally brown and I would like to dye it back to a brown shade, would I be able to do this with out my hair going green?

Your hair has turned ginger due to you not leaving the bleach on long enough. Bleach strips out hair colour one by one. So it will take out the black, the brown, the red, then orange, etc until it goes to pure white. As the colour is sort out of built in layers.
You have got a patchy result because you might have applied it unevenly. When colouring the hair, you first apply the colour to the mid lengths, ends then roots in the end.

Dying it back to brown might be a bit tricky as your colour now is uneven. And to avoid your hair having a green cast, you need to put on a base shade.

You will really need to see your hair stylist to help you out as you want to end up with an even result and not patchy.
