Anywhere the tape and or glue can stick to skin ....it will stick ! Yes, you will need more of a mushroom shape template to cover your front hairline area and the center of your head. Your template wont be very big but that wont matter. They make all different sizes and shapes of tape. As stated, you still got good side and back hair to blend in with the unit, so use it. You just have to go for it and see how it goes. You can always change the next order.
