Thanking god my family lineage doesn't have a single bald person

Well it can also be caused environmentally. Before I was born my grandfather fell into a ditch that had a mysterious chemical spill, he spent two weeks bedridden, after which he went from a full head of bright red hair to mostly bald and his hair going white. Chemo treatments for cancer also tend to cause balding, though apparently the risk of that can be greatly reduced by basically just chilling the scalp during the treatment.

Currently there is a pretty good understanding of the genes, proteins, and hormones involved. So reliable pharmaceutical treatments to reverse balding, should appear within twenty years. Assuming natural balding, as environmental cases from poisoning likely involve the death of hair follicles, which would require more involved treatments than rubbing some lotion on.
