Well, thats not "my" true info. Official research results: PMC7882915, Johns Hopkins University School of Medicine etc

I really sorry for your family members died from COVID. But pushing barbers to do what you ask won't help you to avoid COVID. You can fool yourself, but, sorry, this is reality.

BTW, CDC/WHO has managed pandemic extremely bad.

COVID binds through eyes. When you are staying in closed room with enough viral load, masks on people are useless (well, they provide some psychological comfort probably). Sorry to say that. You might wanted to use full face respirator or tight goggles with mask in closed room to avoid virus to bind through air. Mask on barber won't make a big difference.

BTW, I have seen vaccinated catching virus, unvaccinated, with masks and without masks, people staying in isolation at home, people that were going out actively... all got virus :-) all got it multiple times... including myself, recent strain caught a few months ago in Quebec City, Canada. Ironically first one in 2020 caught in Toronto, Canada as well.

Sometimes people are just looking for psychological comfort, not real protection. Psychological state impacts overall body state, including immune system, that is the only protector against covid. So fooling yourself that you are protected can actually protect :-)

Nobody wants to be sick but it is a new reality these days. The only way to protect yourself from covid is to ask barber to do a haircut on open air and in mask and then go back to home, cut all connection with people, don't go to any stores etc. Don't fool yourself, mask on barber in closed room with unknown viral load won't help.

Wearing mask will help only if all barbers and all customers wear mask and all the time they are in the room? The viral load existing in air won't magically reset if barber will wear mask just when you come :-)

don't forget, covid perfectly binds through eyes :-)

On a side note.

3+ years into pandemic. Did someone still did not catch COVID? Any reason you care specifically about COVID and not about respiratory viruses in general? I would personally wish sick people to wear masks despite what kind of respiratory virus/bacteria they have or just take sick day if possible and stay home.
