One complicated option I am pondering, mostly inspired by people wondering what I'd look like with a beard - let my hair grow out for a couple months more, and grow in a beard. Then bleach it as pale as I'm willing to get it, and wear it that way for a week, give or take. Then go purple or blue for a weekend, and shave off the beard. When that is over, get it cut short again and dye black over the bright colour. The final result would be like what I have now, but black, but it'd be a long, overly complicated process to get there. The growing out of the hair is necessary, because my hair as I have it now is too short to really showcase a properly iridescent colour. I'd need to find a reason to have the funky coloured hair, and take a couple days off to enjoy it, so I'd likely wait for something weird and interesting to come up sometime between November and January, if I started now.
Because I love waffles, I have made a poll so that all may try to sway me in my indecision;
What should I do with my hair?
