This. If you have a haircut without masks, your barber is inhaling the water droplets you exhale and vise versa. You and they stylist are breathing within a foot of each other. Hair stylists are putting their lives on the line, and if they catch Covid they're putting the lives of all their customers--and their customers families--on the line. I ain't goin near a hairstylist if at least one of us isn't wearing a mask. Not dentists, either.
