Finasteride use before hair transplant? Want to maximize results and minimize the chances of sides effects.

Since I want to maximize results and minimize the chances of sides effects I decided to go with the lowest dosage which would deliver me results: 0.02mg/daily. Therefore my question, will the 70% DHT reduction (through the 1mg pill) every 50 days be sufficient to deliver results after 3-4 months, the same way a DAILY 20% DHT reduction does (through a 0.02mg pill)? In other words is 1mg/50days as effective as 0.02mg/1d, considering serum DHT levels return to normal after 14 days?
