I mean like anywhere, depends on where you apply. Many people won’t care, some will. I’d say that people will care less here other than San Francisco, LA, and New York, so long as you’re qualified. Losing the blue hair may increase your chances of finding a job, but I’d guess that employers who aren’t chill with colorful hair will be less chill overall. Find someone who is chill with your hair, they’ll be chill overall, if you get your work done. Not everyone will be, but plenty will.
