I'm not sure anyone would be encouraged by my "look", though the haircut is just fine really.
It works like this for me at 46. If I was still working as v.p. finance and wearing a tailored suit every day. I would have to go to my regular barber in Toronto. He cuts with scissors only, and the result looks like something that clippers couldn't do but as a balding guy with short hair, that difference is subttle. If you have brad pitt hair or something, then only the buzz cut would be home doable at home, he has dozens of styling options.
I live, however, in the suburbs and now work out of my house. If I go to a local place, they do a cut that is 80% clippers, and 20% detailed. It depends on who I get as to whether the hair looks better given their "Interpretation" etc... However, by the end of say day two, post pro cut in the suburbs, Nobody will tell the difference. I vary the length between 1/4, but mostly,1/2" The back gets cut square, the ears get cut to the profile of the ears. The ears are then thinned by using a comb to tilt the hair up and trim it with the bare wahl clippers. It''s easy, and it looks really neat. If you kept on top of it, vs say letting your barber at it less often than you should, your overall look would be better.
I use a pair of shears I picked up for about 50 bucks seems to work on everyone. I have a simple wahl clipper for detailing, and an Oster that is 110 only with plastic guides. At some point when I am in the big city, I'm going to get the kind of clippers with metal guides the barbers use
The thing with clippers is they will eventually get everything the same length, but you may miss a few spots. Just keep cutting. You can't make it look real bad, but you need a strategy for the edges. When I did it all myself, I cut everything to a given length, then I use the right side taper around the right ear, and the left for the left ear. I could go out in public, but not as good as some handwork.
