Heartburn=hair?

I've heard if you have a lot of heartburn while pregnant, it means your baby will be born with a lot of hair already. I'm mainly wondering because I had zero heartburn with my son & he came out practically bald lol but this pregnancy I've been having crazy heartburn since about 20 weeks, so wondering if our little girl will be coming out with a bunch of hair 😊 has this held true for any of you or is it just an old wives tale?
