Final answer:
Hot towels on facial hair can soften the hair, open facial pores for a closer shave, reduce ingrown hairs, and moisturize the skin.
Step-by-step explanation:
The application of hot towels on facial hair is known to have several effects. Heat from the towels can help to soften the hair, making it easier to trim or shave. The warmth opens up facial pores, allowing for a closer shave and helping to reduce the risk of ingrown hairs. Additionally, the steam from a hot towel can moisturize the skin, enhancing the overall shaving experience. While the heat does not directly affect hair growth, it facilitates grooming and can promote better skin health, which indirectly can impact the quality of facial hair.
