Both Propecia and Minoxidil definitely can work in the front of the scalp as long as there is some hair in the area. Although their mechanisms of action are different, both Propecia (finasteride) and Rogaine (minoxidil) act to thicken miniaturized hair regardless of where it is on the scalp. In fact, there are published data1 demonstrating this improvement with finasteride in a controlled clinical trial of men with frontal hair loss.
