in my opinion. absolutely. dried blood in the hair is a perfect growth media for bacteria. while some clinicians may dispute this advice and say "no hair washing for one week or until the staples are out" i have never in over 40 years of clinical practice encountered a post-suturing infection from someone who's hair is too clean. use a mild soap. do not scrub against those staples so that the wound may come apart (personally i do not really like or use staples. i consider it a lazy clinician's fast treatment. i prefer good 'ol sutures that take longer but easier to close those skin edges). rinse with shower water and then blow dry your hair. you can use a tiny amount of antibacterial cream on the wound afterwards if you want using a q-tip. just a tiny amount. a clean wound area is going to make the removal of the staples easier too because you will not have deal with a bloody scab.
can you wash your hair with staples in a wound in your head?
