How long does it take for the wound to scab?

How long does the wound scab fall off? It needs to be decided according to the wound site of the patient. If it is a head and neck wound, the scab falls off in about ten days. If it is a waist and abdomen wound, the wound scab falls off in about 15~20 days. In addition, the time of wound scab is also related to the patient's diet. It is recommended to eat more nutritious and light foods at ordinary times.
