I don’t think conditioner and oil is part of washing. Besides, I have never used oil on my head-, chest-, arm-, whatever-hair, and still the beard is the only one that randomly goes itchy sometimes.
That’s because afaik beard hair is structurally different from “regular” hair.
And depending on your skin and “head”-hair type your scalp can become itchy too. Which is why some people prefer to use oil instead of soap for their scalp.
Define “washed well”. Most men I have encountered complaining about irritated or itchy under their beard don’t use oil or moisturizer.
