Yes, if I had two people show up for a social media manager job, and Person A was dressed nicely while Person B was wearing torn jeans and a stretched out t-shirt, unless Person B destroys Person A in experience, skill, and so on, I'm going to naturally lean toward Person A because they look like they care.
If you think there's something wrong with that, cool.
That's a completely logical and appropriate response. I had a write up elaborating then I was like 'this is fucking stupid clearly Person A is presenting themselves professionally and cares enough about the interview I shouldn't have to justify this'. Because really I don't see any point in justifying it to the 1% of people who don't understand.
I think to me it boils down to a persons opinion of what is unprofessional or not. Very lightly colored pink hair is not remotely unprofessional imo and it didn't even cross my mind for a second that it might come up as an issue that it was until she told me about it.
I wouldn't care about hair color personally unless it was super distracting. If the person looks put together regardless of hair color or whatever and knows their stuff that's good. I do know though that in the corporate world a lot of times that's frowned on so it isn't surprising at all they would request her to not have her hair lightly pink. Maybe once the older heads of these companies leave their posts and younger people start filling in the positions things will change. ---
