Hair color that truned black

I dyed my hair temporarily and the dye was supposed to come out in 6 days and it did. I then dyed my hair chesnut and it came out red. I was so upset so i redyed my hair dark brown and it came out black. I then bought a temporarily dye and it was lighter to try and take out the remaining red and lighten my hair, but my hair is now 100% black, with purpe/red at the roots, so i decided not to dye it anymore. How do i remove it or fix my hair. Also my hair isn't to damaged and I wanted to go to a professional is that a good thing to do? Are there any at home remedies that will help a little??
