People, THIS IS AN N OF 2, not 160, and we should not make ANY policy decisions based on it. Maybe these two hairstylists were not shedding much virus. Maybe the ventilation in their shops was excellent. Maybe there was something else going on.
This doesn't even show that masks prevent the spread because we don't know what would've happened without a mask. Maybe the relatively short time needed for a haircut isn't long enough to spread the virus. Other studies have suggested that longer contact is necessary.
Also, they tested fewer than half the clients, so they can't rule out asymptomatic cases.
This is, at best, an interesting anecdote. But not a useful one.
