I generally agree, though it's my understanding that, so far as the hairline goes, when it's gone it's gone.
I have a pretty advanced receeding hairline and had next to no hair on the crown and top of my head. Now, a year into Dutasteride & Minoxidil, I've got loads of hair on the top of my head, with more rolling in as time advances relentlessly forward, but have seen little improvement across the hairline.
Once I'm happy I've done all I can with meds it'll be a job for surgery to deal with the front, which is a bummer, but you do what you can with the hand you're dealt.
