Eyelashes can grow back if the follicle is not damaged. If the follicles are damaged, there is no way to grow new ones. Eyelashes are metabolized just like hair, but the regrowth cycle is different. Eyelashes grow slowly, and if the hair follicle is not damaged, they can grow back without too much concern. When the hair follicles are damaged by burning, the follicles in the area are destroyed and new eyelashes cannot grow. You will need to go to a regular hospital to diagnose the damage to the hair follicles, then extract the follicles for culture, and finally grow new eyelashes by planting the follicles. If your eyelashes are damaged by fire, you need to protect your eyes first and then go to the hospital for a checkup. Do not delay to avoid the occurrence of adverse symptoms, which may affect your normal life.
