 [ Symptoms ] what can i use for thrush [ Disease ] that is a good and very reasonable question i suggest you call your surgeon is office and ask the nurse or pa generally whenever someone has scalp incisions we recommend they wait until the incisions are fully healed staplessutures removed and so on before they apply any hair color you want to make sure you do not have any openings in the skin when you apply the colorant because this could be irritating or lead to infection so again best bet is to call your surgeon is office and ask they can give you specific information glad to hear you survived the brain aneurysm
