Bald is hot, no matter if natural or just a style thing. However, DO NOT LEAVE GRANDPA HAIR (bald on top, hair on the sides). It's the biggest no-no on guys. If you DO start balding seriously, just shave the entire head. It looks neat and sexy.
And one more thing: you will not make your bald spots less prominent if you let your hair grow and "try" to cover it. Seriously, it doesn't work. In fact, this will make the contrast between bald and hairy spots more clear. Just get some clippers and shave your head completely, either on a typical buzz cut style or even closer to the scalp. This will make the balding spots less prominent, since the contrast will be lower. And yes, it will look (and feel) weird at first, especially if you have never sported that short hair before. But eventually you will get used to it and even start loving it (I know, I have been there, and now I cannot even imagine myself with longer hair).
Whether it's your choice or you cannot do otherwise, just rock your shiny scalp and be happy
