Can Rogaine On Healthy Hair Cause it to Fall Out?

Thanks so much for this resource! I am 3 weeks post op from a HT of 4200 units. I was on propecia for 30 days prior to HT and began Rogaine / Minoxidil 2 weeks post op. I had temple work and work at the front of my hairline. I want to get the best result and minimize shock loss. I have heard Rogaine can cause shedding. Am I at risk for shedding in healthy hair zones if I apply Rogaine in it’s correct dosage to the entire top of my head, temples and along the donor scar?

Rogaine (minoxidil) on healthy hair most likely will not cause shedding, but I would strongly suggest that it only should be applied to areas of concern and not the rest of the head for two key reasons:

1. Cost
2. Side effects (or potential thereof) will occur as the area of treated skin increases

It is also worth noting that minoxidil will not influence the hair transplants to grow any better or any faster.
