Like most things to do with puberty it is very variable and indeed some men never do grow any hair on their scrotum. Next time you go to the beach or the swiming baths you might notice that while some men have a thick growth of hair on their chest, some have much less and others have none at all. Of course some men may have shaved their body hair (and some men also shave their pubic hair and scrotal hair) but many men just don't grow any chest hair at all. Every body is different and some guys have much more body hair than others. If you already have pubic hair, and hair by your anus, you might expect to see some hairs growing (even if they are tiny) on your scrotum, if you are going to grow them.
This is different for each man. Hormones effect body hair. Some people don't have any while others have a lot, so it is your body that will determine how long it takes to grow back.
It is because of puberty and the types of chemicals you use for your hair. The thing that your body produces that keeps your hair a certain color is reducing.
