help orange hair

story time:

basically tonight I went to the salon and got my hair professionally dyed. my goal was to have caramel brown hair but since I naturally have dark hair, the undertones are very red and orange. my hair turned out extremely orange and I hate it so much I cried! tomorrow I made an appointment with another professional to dye my hair back to BLACK, which is my natural color. is it safe to dye my hair two days in a row? how much damage will it do? I really want to get rid of the orange as soon as possible but I just don’t know what to do.
