Hi,
Thanks for updating. Great result.
Regarding medications:
For the first 6-12 months Dr. Demirsoy advises meds like Minoxidil to support the growth.
However, Minoxidil and Finasteride (Propecia) are both typical hair loss products, which can/should be used to maintain your native hair.
Theoretically they need to be taken continuously (forever) otherwise hair may continue to fall.
It is up to and your decision, but it would be it pity if your native hair, especially in the crown, falls in the near future.
Happy new year!
Clemens
