I have dark hair (black) I want to remove the red highlights from my hair, they look horrid... The stylist did them wrong, I just want to go one solid color and let my hair recover

Red is really hard to remove. Your best bet is to go to a hairdresser, especially since you just colored your hair, and doing so again so soon will cause damage.

I would recommend a different hairdresser than the one that damaged your hair to begin with.

Good luck.
