I do very much agree that it's inadvisable to add a turban to depiction of person unless they choose themselves.

That being said, as an pedantic, unshorn hair, turban wearing Sikh I'm not sure I'd describe dastaarbandi as any sort of ceremony granting authorization.

Yes, that was overly loose wording on my part. I wanted to convey that there are rituals and formalisms around wearing turbans.
