Doctors had differing opinions -- ranging from five to 20 years -- on how soon stem cells would be available. But the consensus was that hair treatments would change.
Bernstein, who estimates something will be available in five to 10 years, said that two barriers remain to having stem cells produce a baldness treatment.
The first, he said, was then when some stem cells multiply, they lose the ability to grow hair. The second is that it is often difficult to produce hair that is cosmetically useful.
"We can't multiply the hair well at this point or make it cosmetically oriented," Bernstein said. "Those two problems are really a big barrier."
Men who are in the process of losing their hair have several options.
Men who have already lost their hair have fewer.
"You're looking at a hair transplant, and I think they're wonderful if they're done by a skilled physician," Newburger said.
But men who want to do something about baldness but have already lost their hair and have little hair left on their head to transplant, or who for other reasons dislike medical interventions, still have an option.
"Hairpieces and wigs remain an important option for patients who either can't tolerate the medications, don't want to take something systemically, don't want the hair transplant surgery, don't have enough hair for transplantation," Bernstein said.
While he cited the maintenance costs as a strike against hairpieces, they do present a valid choice for some men.
"People who just want coverage -- wigs and hairpieces remain an excellent option for them," he said.
