Hair loss and genetic balding produce a “Tug of War”

I am 34.5 years old today, I started finasteride and minoxidil on September 16, 2023 and I am experiencing great results after 3-4 months. And so far I see and notice active shedding, and I noticed at the 6 month mark a sort of loss of results. Is this reasonable?

There is a “Tug of war” between your drugs and your genetic hair loss.  “Which one wins?” is your question.   There is no doubt that finasteride, for example, will always either slow, stop or reverse hair loss.  Slowing implies that the hair loss could be ongoing.
