I am quite uncertain about how to prevent overshaving of your own good/full hair hair, every time before you attach your hairpiece.

I have shaved my head properly to make a template, but its the maintaining of the shave that I'm worried about a bit. I can see its nessesary to shave every time before you reapply your hairpiece, but it seems so easy to overshave into your good hair , (on your side and back hair,) if you are not extremely careful.

I have long hair so I don't want to end up overshaving it because it takes a long time to have it grow back. Also of course, I don't want to shave too much off, making my bald area slightly bigger than what my hairpiece covers. With even a bit of my long hair cut off over time, it would also be tough to design a future template that would correctly illustate where my good hair ends and where my balding area begins. This is because I use the long hair as my guide to where my good hair begins, and therefore use my long hair as a guide of where to shave to. I'm afraid that over time I'll shave off more and more of my good/full hair.

Anyone have any suggestions on ways to shave the bald area without over-shaving and without shaving off good hair?

I've tried making what I've called a reverse template, which is an outer portion of a regular template, as a way of creating a sort of guide as to where to shave. However, I've found this is too difficult to get just right. I've tried using edges like a comb too, but this also seems tough to do correctly.

So, what do other people here do? Any advice would be much appreciated.

Place the piece on your head mate then mark your scalp were the edge of the piece comes to, Remove piece and then shave to the marks, Then remove the marks with 99% alcohol if you used a felt tip marker.
