In clinical situations where the scalp itches and bleeds from scratching, this is usually not a problem. Because the scalp is rich in blood supply, a small amount of bleeding does not have much effect and will often heal on its own, not threatening the entire life of the patient. It is also important to pay attention to the root cause of the itchy scalp, otherwise many people may be scratching and bleeding many times, which is more dangerous and may subsequently induce cancer and other possibilities, so find the cause of the itchy scalp, so as to better treatment. Sometimes it’s not just a simple lack of hygiene, but more of a fungal infection such as ringworm, so it’s necessary to go to the hospital early for a consultation.
