I see people talking about clippers and blades and they are measured in numbers like 000, 1,2,3, etc but I was looking at some clippers in the store and they say they come with guards for several hair lengths, each measured in inches such as I believe the lowest one I saw was 1/8". There was 1/4", 1/2", etc. So, how do the numbers correspond to these lengths? I'd assume the blade by itself is 0, right? So if I trimmed it REALLY close that would probably call for 1/8 but then without the guard it would be 0? I dont remember what the brand was but they all had it in inches.
Also.... if your hair was at the shortest length could you use an electric razor like you'd do on your face - the round 3-head type? I use that for regular shaving, dont use a blade. too many nicks on the face years ago. I wonder if that would work for the head too?
I'm leaning toward getting a Clipper and going in stages, real short at first.
