Hi! I noticed that your hair is dyed purple and that you also work in a lab setting. Are your supervisors ok with your color choice? Have you ever been asked to change it? I want to dye my hair an unnatural color but I worry about the "professionalism" I must uphold when looking for jobs/research in a lab setting. Thanks!
I've never had anybody in charge of me comment negatively on anything about my personal appearance in lab, no. My advisor, who is very cool in many ways (and much younger as far as social issues than his generation is), actually seems to enjoy my hair color changes -- the only thing I actually remember him doing is saying, "It's purple now!" and then smiling and wandering off to do whatever. I was even sent to a research grant information session (along with two graduate students) to represent our professors (who were in DC and Europe, respectively) at the time. We discussed professional clothing choices, business card etiquette, and handshaking techniques beforehand, and I was asked what I was wearing but they never asked me to change my hair for it (it was bright blue at the time). (See here.) I typically wear much brighter make-up (glitter!) on presentation days, nobody has ever commented on that either (it helps me have confidence when speaking). Overall, I would say that in my experience, people who work in lab settings tend to look however they want to look. One of our grad students has hair down to his lower back (always in a bun in lab, but as far as men's hair goes, you can tell it's super long). One of our grad students streaked his naturally black hair with bleach-blonde highlights right before his thesis defense. (My hair was a red-purple color with blonde streaks at the time, too.) I've seen guys just straight up covered in tattoos never covering them up, nobody seems to say anything. I've seen professors in lab with shirts bearing beer logos or Led Zeppelin shirts that look like they're really from the 70s (and probably are). We have a professor who is in a metal band who has the hair to go with, ponytail, everyday.
I think in lab, dress code is really a matter of safety first. Secondly, is coming off like you know what you're talking about and can communicate well. Professionalism seems to come much later.HOWEVER, my lab is in a university setting which is going to typically be significantly more liberal than a for-profit or company lab, but I have entered the professional world expressing myself the way I do. I think things are starting to change a little bit in regards to what kinds of alternative are okay. For example, my friend works at a company that is 100% business - office, accounting, travel, meetings, handshakes, company cars - but many of his coworkers have pink/purple/green hair. I am going to ask my committee if they believe I should go back to something natural-colored before my undergraduate thesis defense but I suspect it won't matter. In the end, it is just hair and it is very, very, very easy to dye over it in a pinch. (I've been dying my hair since I was 14 so this is all kind of old-hat to me). You could cover it if you had to or dye it once you scoped out the attitude of the company/lab.
