How close is #0 to bald?
A #0 is the clipper with no guard. It leaves about 1.5 mm, so the scalp shows everywhere, with a visible shadow of stubble.
A razor or foil shaver takes it to smooth skin. The tool does not render a razor shave; #0 is the closest it goes.

Receding hairline or thinning crown
Going very short is a common choice when the hairline is moving back, because it removes the contrast between thin and thick areas.
The tool keeps your real hairline, so what you see is what a real #0 would show.
Before you shave it all off
- Check the back of your head with a second mirror. Ridges and flat spots show at #0.
- Try a #1 or #2 first if you are unsure. You can go to #0 the same day.
- Plan for upkeep. Stubble shows within days, so #0 needs the most frequent touch-ups.
