My husband has only used his razor since September and never had a hole in the foil. Our brother-in-law also has the same razor and no holes. So, my best advice would be to contact Panasonic to see what the life expectancy is. They both say it is the best razor they have ever owned!
No, but I would guess that it might not work so well. I shave with it and it gives an OK shave but leaves many longer hairs on the neck. I would think that longer hair would be hard to catch on your scalp. ps when I need a close shave I use my regular razor. Hope this helps!
