Hair Loss from Z-Plasty Incision in Scalp

Doctor, I recently have had a spot removed from the top of my head. It was necessary to do a z plasty, which is roughly 4 inches in the longest part. I have no natural hair loss, but have been on Propecia for roughly 14 months. Since the surgery, (6 weeks ago) I have significantly thinned in a z pattern on my head, where the incision was made. It actually looks worse than it did 1 week after the surgery. I am very concerned and would like your opinion if I am experiencing what some might classify as shock loss, and if my being on propecia for a year prior would lend itself to me getting my hair back. Thank you

Having any scalp surgery in an area where you are genetically balding will accelerate the hair loss, and it quite possibly may be permanent. Even a scalp surgery like what you described can cause hair loss in non-balding people. Shock loss is usually best prevented by Propecia (finasteride 1mg) in men with genetic hair loss. You will know what will happen in 6-8 months. You may need transplants there if it does not self correct.

For those curious about a Z-plasty, Wikipedia has a nice explanation here.
