It is generally recommended that you can wash your hair in about half a month after surgical removal of a scalp cyst. Sutures can be removed in 5~7 days after scalp cyst surgery, and hair can be washed after 3~7 days, so it is recommended to wash your hair in about half a month after surgery. It is recommended to wash your hair about half a month after the surgery because the wound of this surgery is small and the incision on the scalp generally heals faster. When you wash your hair, it is inevitable that the wound will come into contact with water. Be careful not to soak the wound in water for a long time. Wipe the wound dry promptly after exposure to water. Immediately after washing your hair, wipe the wound with an antiseptic solution such as iodophor to avoid infection. At the same time, in the postoperative recovery period, to follow the doctor’s instructions for medication, and must pay attention to good local hygiene, do not touch with dirty hands to avoid infection.
