Please help. I am a medium brunette and

I colored my hair a golden brown. It turned a little red pink so I decided to go back over it a second time with a different brown dye and its bright orange. I have work tomorrow and I'm freaking out. It's neon red/orange. I can't color it again or my hair will fry. I shouldn't of colored it at home but did. What should I do? It was a demi permanent color. Please help :(

Update

I didn't bleach it. I used a wella color from

Sally's. I didn't like the result because it looked a little pink so I purchased One n only 4c color I used 10 developer the lady told me it would make my brown a more golden brown. It's not yellow it's orange would a purple shampoo even help? Plus I've colored it twice trying to fix it I don't think the salon could do anything for it? I don't know how it turned orange. It's been colored twice in the past 42 hours.

Update # 2 I fixed it!!!!! I used baking soda dish soap purple shampoo clarifying shampoo and hot coconut oil YAY !!!!
