I wrote about this here: https://baldingblog.com/selecting-hair-transplant-doctor/
This is a global approach to selecting any doctor for cosmetic work anywhere. We have monthly open house events for prospective patients to (1) meet many patients one-on-one and judge the quality of the work for themselves, (2) see a surgery live actually on the day of the Open House and (3) get a free consultation to get a Master Plan built for your hair covering short and long term hair loss possibilities. Few doctors will do this because dissatisfied patients come and can ruin such an event as happened a number of years ago where former patients actually picketed the doctor’s office. Your doctor should be proud of his/her patients and willing to bring patients for meetings to educate you. I also started doing this in 1993 at medical meeting where I brought my patients to teach doctors what a good hair transplant should look like. After many years, the ISHRS (International society) had established patient ‘live viewing’ sessions at every annual meeting. What is good for the doctor, should be good for you, the patient.
