How can I conceive a baby that is born with a head full of hair?

I'm actually just curious, I've always loved babies (especially baby girls) who are born with a head full of brown hair better than bald babies. I'm wondering if it's possible to conceive a baby that is born with a head full of hair? I'm wondering how does it work and is there any way knowing if your baby will be born with a head full of hair vs a bald baby?there isnt anything you can do to make your baby have hair when he or she is born its a heriditary thing that isnt controllable but they say when your pregnant if you have alot of heartburn your baby will have a head full of hair but thats an old wifes tell the only way to know before your baby is born i guess is to do a 3d 4d ultra sound even then im not sure if you can see the hair..
