Well i am from delhi aswell . . I did explore a couple of options in delhi BUT
1. They could not show me , what u call , a catalogue of their past patients and their results
2. Those who did (one doctor if i remember correctly) , were charging a lot about rs90-120 per graft .
Dr bhatti , on the other hand , does a hair transplant every single day so he has loads of experience plus with a little bargaining with the mgmt , i cud get my HT done at less than 50% of the price offered in delhi .
hope it helps
