It's pretty common for dogs to be afraid of people who look different to them, and head gear and beards scare lots of dogs who aren't used to them. My young BC mix sometimes sees someone she isn't sure of...and, yes, it can be embarrassing. She's not aggressive, it's more like "Hey, you, you look strange, don't come close too me. Hey, Mom, do you see that odd person, better keep an eye on them!". The worst that happened to me was Molly barking at a young woman with CP using crutches, argh, mortifying, to say the least. Fortunately, the woman is very animal savvy (we met her at a horse barn) and knew what was going on and wasn't offended, she laughed at the silly dog.
Our dog trainer has us work on attention training, getting the dog to watch me and make eye contact with me (using treats as the reward for checking in). He told us not to get too close to scary people but to stay at a distance from which the dog was unworried enough to maintain focus on me. Work our way closer, gradually. If the dog starts focusing on the scary person, rather than me, we were too close for comfort again. Also, don't baby talk and pet the dog and try to reassure it that everything is OK, that will just reinforce the idea that the person is scary. Stay calm, matter of fact...dog is silly and doesn't need coddling as there's nothing to be afraid of.
This has gotten us to the point that men with beards and hats are OK, as are tall men. She used to be afraid of kids with backpacks on, but she's totally over that. She is recently worried about people who are very very overweight, don't ask me where that came from and it's also embarassing, so we're doing the "pay attention to ME" and keeping our distance until she stops reacting. Molly is a somewhat timid dog and it is difficult to guess who will worry her next, getting her out among people as much as I can, so she sees all kinds of people is important, but, as we live in a sem-rural area, she doesn't see a great variety of people on a daily basis.
