Does a Juvenile Hairline at 29 Years Old Indicate That I Won’t Bald?

I am a 29 year old male who still has his jeuvenile hairline and low, thick, full hair. I have heard that men who retain their jeuvenile hairlines by 30 years old rarily ever go bald early, if ever. My father kept his jeuvenile hairline and has only lost a very small amount of hair in recent years since he has been in his fifties. I have noticed other older men who have a complete full head of hair sometimes have a jeuvenile hairline. So is there any truth to this? Is a jeuvenile hairline at 29 a good sign?

A juvenile hairline at the age of 29 without evidence of balding says that there is a good possibility that you may never bald (at least not in the front)… but to be sure, get your hair mapped out for miniaturization, which would show any signs of balding at your age.
