That is utter nonsense.<p>I use a $20 safety razor from Amazon. It works better than any cheap disposable with off the shelf gel or foam. I don&#x27;t use a brush and I don&#x27;t lather any differently than I did with a disposable.<p>The safety razor does not shave quite as close but that turns out to be a positive for me (especially in area&#x27;s other than your face).
