Option 3 is actually the plot of an episode of the medical drama series "New Amsterdam". The main character of the show is the director of a fiction NYC public hospital. In episode 4 of season 2 he tries to encourage black men to get medical checkups. He choses to teach the barbers how to take blood pressure and prescribe some basic meds. The episode centers around the mistrust that black people in the US have of public healthcare, and how barbers are a natural social center for that community.
Once upon a time, some barbers had dual jobs: cutting hair and taking care of common medical conditions. The first modern surgeon was a barber by trade. The red and white of barber poles represent blood and bandages, after all.
