Recreating the Spiral in the Crown

I am a 45 year old male who is thinning in the front and who is developing a moderate bald spot on the crown. Both issues can be successfully masked by products such as Toppik, but eventually this solution will fail. My question for you is twofold:

1) Is Propecia (finasteride) efficacious in slowing or stopping hair loss in someone of my age.
2) Is it possible to recreate the natural “spiral” pattern at the crown, as it occurs with one’s original hair pattern, with a transplant.

Thanks for your time.

1. Assuming that your hair is healthy and that there is no significant miniaturization in the donor area, yes, Propecia can positively impact the crown area with some regrowth in about 30% – 40% of men of your age.
2. Assuming the supply/demand ratio of your donor hair / recipient area is favorable, you can easily replace the spiral pattern in the crown. It requires a skillful, experienced surgeon.
