From my view, short hair (buzzcut) fits to your head. Why you are considering a HT?
I did it in a hairmill in turkey, now I regret every day my decision 1. because I did it in a hairmill and 2. i was a NW5a, so I need a second HT ( they didn’t tell me that) and of course a repair. They used in my hairline lot of double and tribbles, it looks really pluggy!
And they didn‘t tell me to go on fin or something else. So when I want to keep my native hair, I have to take fin or minox. But I don‘t want it.
Make your decision very wisely and try not to save money!
