Dearest Elder Goth, I was wondering if you had some advice about hair coloring? I recently had to change jobs from one with a lax dress code where hair color wasn't an issue to one that requires a "natural" hair color. I had previously bleached my hair and managed a blue to teal ombre look, then went back to my natural black. The problem is, the black hair dye keeps washing out rapidly, leaving green/gray streaks. Do you have any tips for how to keep the color from washing out?
