After having craniotomy surgery, you can wash your hair in about 7~10 days, but the exact time to wash your hair has to do with a number of factors, such as individual physical fitness, the recovery of the wound, and post-operative care.
After having a craniotomy, there will be obvious wounds on the head, which will take some time to recover. However, the scalp has a richer blood flow and the wound may heal faster after the surgery.
If the individual is in good physical condition, pays special attention to wound care after the surgery, and there is no inflammation or infection, the hair can be washed in about 7 days.
However, if the individual’s physical condition is poor, the recovery is slow, or no attention is paid to wound care after the surgery, and localized inflammation and infection occurs, an interval of 10 days or more is required before washing hair.
