When i start taking Propecia, how long until it takes effect?   Does it take a few weeks in your system before it starts blocking DHT or is it  immediate?   Thanks.

Thank you for your inquiry.

Finasteride (marketed as Propecia)  starts to work right away however, it might take up to 3 months to see less hair loss.    In order to see any visual effects such as the thickening and strengthening of miniaturized hairs, it takes up to 6-12 months.

Please understand that you may experience additional shedding over the first couple months.   This is actually normal and an indication that the hair loss medication is working.
