> Works for the sides, but how to do make a smooth transition to the top? Without cutting it equally short everywhere?
My technique is to keep the machine at the same angle (blades roughly vertical) while moving upwards: as it slides over the curvature at the top, the distance between the base of the hair and the cutter increases smoothly.
This is with the biggest comb clipped on.
I then remove the comb and use my fingers instead, sliding the blade on top of them, to get a longer cut than with the combs.
The machine I use is a Panasonic ER-1611 which is not cheap, but here you can see a picture including a side view for the angle:

I've also used before a cheaper Phillips that worked fine but wore out after some years, and the first one was a Solac that I still have in Spain and works as new.
The technique works similarly for all of them, but both the Solac and the Panasonic were sold as "for professional use" and they do work noticeably better.
I've been doing this since shortly before starting my military service in Spain long ago. You get better with practice.
Oh, and try to arrange a couple of parallel mirrors so that you can see the back of your head.
Giving yourself a fade isn't as hard as it seems. Short answer: use different sizes of the plastic guards, and do a bit of a flicking outward motion with your wrist where you want to blend.
That doesn't always work, depending on the shape of your head, the texture of your hair, etc.
I for one don't care about it much, and my job allows me not to care, but many people do care for both personal and professional reasons. Any kind of job where you want to persuade people basically requires the best look you can afford. It's basically an investment.
Gah to think of all the times I managed to fail to persuade people because I have short hair :)
To me it is a mix of feeling that spending money on cutting my hair is wasteful, spending time to go to a hairdresser is wasteful and so on. It's just a maintenance chore. And I don't feel it has ever caused me to perform subpar in my job or to have people take my arguments less serious. But I can see that form some people this might be the case.
In a way this is a luxury that men can afford themselves, if a woman would go to work with a very short hair it would immediately count as some statement rather than being efficient.
I'm a man.
