I work in a call center for a large health insurance company with a fairly relaxed culture and dress code. Around here, the hair thing wouldn’t raise any eyebrows. I did see someone ‘talked to’ about wearing jeans with holes in them, but as long as overall casual appearance is neat and clothes are in good shape they wouldn’t care about hair streaks. go you!
Anyone else assume from the title of the thread that it was going to be a rant about gingers?
Why would anyone need to rant about other people’s natural hair color?
This is what I’m hoping. But… the person whom I asked has scheduled a 30 minute meeting with me to talk about it today, so I’m guessing it’s going to be “complicated.” If the answer was a simple yes, she would have just emailed that.
If nothing else, I could dye it some naturally unnatural color (for me). Brassy blonde or straight black or fiery red (gingers are cool, as long as they’re girls–or so goes the trope). I’m tired of being the mousy, dirty blondish brownish brunette all the time.
And besides, on this side of the pond, we see no reason to oppress this beautiful, beautiful minority.
I laugh whenever I have to sign a HR policy regarding ‘unnatural hair colours’ because there’s not a woman I work with who is sporting their ‘natural’ colour. 
Hell, I didn’t even know what mine was until a couple years ago. As it’s now ‘grey’, the mystery continues…
Today green won’t be an unnatural hair color in the workplace.
