For the fewer unknown, Propecia aka Finasteride is a Dihydro testosterone (DHT) blocker. It is one of the most potent drug to halt ongoing process of baldness in males.
It has been debated over the years about how much and how long it is to be made a part of a man’s lifestyle.
Propecia’s importance and continuation depends on a few factors-
1.Age – The younger the age more the importance is to be emphasized or with age a strong donor may deplete (undergo miniaturization) over time.
This owes to the only relative independancy of donor grafts to DHT(Dihydro testosterone).
This when supplemented with propecia ensures them to stay strong, and hence it has unequivocal importance.
2. Presence of pre-existing hair on recepient area-
How bald is a person; is to be taken into consideration here
A completely bald scalp without any hair follicle ie. A clean canvas with every follicle planted from the (donor scalp & beard) has an advantage (if we can say so!!)
These transplanted hair grow and stay without supplementation
( Note: As mentioned in point no.1, we are to take into account future miniaturization of donor)
However a scalp with pre-existing hair needs saving from ongoing or future process of thinning and baldness, thus making propecia a must.
In conclusion,propecia thus help your pre-existing and transplanted hair to large extends; more in case of pre-existing ones.
If someone has reservations against propecia, one shall keep in mind for a future ‘re-transplant’, especially an individual with a strong genetic predisposition.
