Yep you get it.
Preventing further loss is key as hair loss is progressive and you only have X amount of donor hair so it needs to be used wisely.
The more native hair you can keep on top then the fewer hT's you will require and not be chasing your tail so to speak.
Meds do help the mid/crown generally and some for some it helps the front.
For me meds prevented further loss of the mid /crown ( and thickened them up) and due to building this strong platform i build the front up via HT's
If you are a builder and plan to build a strong wall to stand the test of time - you put it on a strong foundation
