There's no evidence OTC antibacterial soaps prevent disease more than washing with plain soap and water. Some antibacterial drugs can do more harm than good.
This aligns with what I've always been told. The mechanical action of thoroughly washing your hands for 20 seconds + the surfactant in the soap is enough to allow the subsequent rinse and dry to physically remove shit from your hands.
Same with your pits and junk. Just a normal bar of unscented soap is all you need to not be stinky and prevent bacterial growth particularly during the summer. Unless you have special needs based on skin conditions or gland conditions of course.
hair too, most people most of the time will do just fine with a simple bar of soap in the shower, all shampoo does is detonate a nuclear bomb on your scalp so you then have to put oil back with conditioner, it's the textbook definition of making you dependent on a product.
you only need shampoo if you have some specific scalp condition or you decided to rub shit on your head, otherwise soap is absolutely fine and frankly you'll probably do fine with just water and rubbing yourself down thoroughly.
i believe that is why people invented perfume several hundreds of years ago, and coconut can be achieved by simply getting some cocoa butter and using it as skin lotion.
Do I need Ritual of Oudh body scrub after my Summer Rain shower gel and afterwards before going out some Serendipity parfume? Fuck No! Does it help me feel good and I frankly got enough negativity in my life already and need some positive feelings? Yeah!
