<s>[INST] context: About Pre-op shaving Bailey writes - "Pre-op shaving should be avoided except for aesthetic reasons or prevent adherence of dressing. If it is to be done, it should be undertaken immediately before surgery as there is a higher infection rate when it is performed the night before, because minor skin injury enhances superficial bacterial colonisation."
Farquharson op. surgery also supports the above view and writes that pre op shaving can be done to get a clear view but it does not reduce infection.
