Posting a lot of thread this

Just curious, but I have seen a few comments about how curls are not appropriate for work. This confuses me..... what type of jobs have this? Why would it be seen as unprofessional? It is genetics.....isn't it like saying my shortness is not appropriate for my job? Or my freckles are unprofessional?

Someone enlighten me how something you have NO control over would be considered bad for a job..... am I just really naieve or something?
