Topical minoxidil

If I apply minoxidil only on crown then will it protect hair where it’s applied or the entire head?
Applying minoxidil topically impacts the area where you apply it, not other parts of the scalp; however, there is overflow and some systemic absorption. My wife took it for her hairline, but it caused facial hair to grow showing some systemic spillover.
