Curly hair

Hey there so Monday I go in the procedure to clean out my uterus and stuff from polyps thing is the hospital told me to wash my body and my biracial curly hair in antibacterial soap for 5 days leading to the surgery! I cannot wash my curly hair with antibacterial soap it's taken me years and I mean years to get my curls healthy and where their at now. Washing with antibacterial soap for 5 days will set my curls back years! I think freaking out more about that then the actual procedure. What do I do?!?!
