Back in the early 80's, my healthcare mega-corp had as part of their dress code requirements that employees display no visible tattoos or body piercings apart from earrings that were ambiguously deemed to be "modest and tasteful".
Extreme hairstyles were also expressly prohibited. Those included "unnatural hair colors" and in the case of men, a shaved head.
