Oxygen masks are designed to seal with the skin. In case of toxic smoke in the cockpit beard hairs won't allow this sealing.
An example of that though it's not aviation are the Iranian soldiers during Iran Iraq war. Masks couldn't protect them from chemical weapons cause beards allowed toxic air enter the mask.
I am pretty sure that a report of a future accident will include it.
I think that I am not the only one who thought that, still no one is bothered to enforce regulations
And of course the oxygen leak cause of hairs in case of cabin pressure loss
