Make sure to like wet every part of your body first, next when your scalp is itchy/greasy/smelly go give it shampoo and brush it with your hand gently, add shampoo when you actually need it then wash it till no shampoo.
In terms of body, usually the smelliest part is found on your armpit, private part... just give it body wash and rub it as usual then wash it away. This is recommended, to like shave the armpit and the private part infront(not the ass) too every 40 days, it helps for germs to not stick in hairy stuff.
To test if your smelly after a day or 2, just smell your armpit, if its sour then take a bath, in terms of ass, you can grab a tissue and then rub it near the hole, if there is shit then thats a sign to give body wash, rub it and then wash away.
Usually I take bath in morning, after exercise and before going to sleep. Next step is drying, go grab a towel to dry your scalp until like its cool with little wetness. Then use a different towel to dry your body, the private part is expected to be dry...
This is my experience anyways... so to avoid confusion you can always watch how others dry their hair or body with towel on youtube. Then hopefully you'll be fine.
