No guard clippers provide the impression of a shaved head, only the blade does the deal. Doing the deal w/ a blade, and reasonable exfoliation will remove the issue of "dead skin."
I guess you could do extra exfoliation w/ a loofa sponge or whatever, but if you really want it clean it's got to be the blade. Blade for 30 days, you should get used to it and if it's really for you, you'll keep it.
