If customer had high blood pressure, the barber would intervene. The customer would be urged to see a doctor. If the man didn’t have a doctor, then a visit to one would be set up. Customers who went to a doctor will get their next haircut free of charge. The study lasted ten months. All of the men had their blood pressure taken at the start. They also received educational material about hypertension. |
