Thought about that, but found a situation before trying it. I think I will do that next time... which is kinda sad, cause really, my experience makes me really valuable.
But in the end, would you really want to go work for a shop like that? If they don't want you based on the color of your beard, then I wonder what "other" surprises lurk around the corner..
I'm in my mid-thirties, so please take that into an account. Also I know that these are the questions that I have to ponder in the coming years, so your insights are highly valued.
What about tinting ("dieing?" sorry for not knowing the word in English) your hair? It's superficial, but if it lands a job, it's fair.
