How do you warm up a comb not using the stove?

To warm up a comb without using a stove, you can run it under hot water from the tap for a few moments, ensuring it's not too hot to touch. Alternatively, you can hold the comb in your hands and rub it vigorously to transfer heat from your body. Another option is to place the comb near a heat source, like a radiator or a warm hairdryer, for a short period.
