Why having a hair transplant? Just look at the people around you, it is fashion to be bald. And no, I am not bald I still have plenty of hair and I am 76 years old. But my wife cuts my hair to NO.1 every 4 weeks because I like very short hair.
Do what I do, I just eat fruits in the morning don't have lunch (because I get up late) and just a small dinner, I am not overweight or obese, don't drink spirits or beer but enjoy a few glasses of red wine at night.
