In an effort to save some money I decided to dye my own hair, I basically had a few stray grey hairs & wanted them gone. I had medium brown hair & bought a medium brown over the counter hair dye & now parts of my hair are almost black, the color came out uneven. Does anyone know how I can get back to my medium brown, do I have to bleach it, is it even possible? Any experience with black hair would be great.
