Generally, the scabs will fall off in about 10 days, but this cannot be generalized, as it depends on the amount of bleeding, the depth of the wound, and the thickness of the scabs. If the formation of the wound is shallow, the formation of the blood scab is thin, the blood scab will fall off the time will be shorter, generally about 10 days can fall off. If the wound is deeper and bleeds more, and the scab is thicker, the time for the scab to fall off will be longer, and it may take half a month to a month for the scab to fall off. In addition, the physical condition also has a certain effect on the shedding of the scabs, and the time for the scabs to fall off will be shorter for people with good physical condition compared to those with poor physical condition. Before the scabs fall off, the wounds should be kept clean, do not touch water, do not scratch, and avoid cold and spicy food so as not to affect the healing of the wounds.
