So I have been shaving my head for quite a while, and just got the schick xtreme 3 razor. And omg it made me look the baldest I have ever looked. Want to know which looks better? Pic 1, pic 2 or pic 3. I could always go back to gillette fusion or shortest clippers if the balder look does not look as good.
Pic #1 looks great. I think if you're going to be bald, your head should be smooth as can be. I've been using thr Schick Extreme 3 disposable for many years. And I shave every day in the shower. I've gotten to the point that I can't stand the stubble, and I want my head super smooth daily.
Pic 1, the closer the shave the better. Since your hair is dark, you have shadow if it is not as close as possible. When you are older and your hair turns gray (assuming it does), you will be able to be shadow free with any of them. And I will add, with the shaved head, the more facial hair the better IMO.
Number one and number two both look really good to me
