All it takes is a saliva swab which is then sent to a lab. Researchers look for a genetic variation on the x-chromosome that's linked to hair loss.
"There's something psychological about having your hair. It's not totally getting old," said Tom Mastanduono.
Tom just got his results.
"Wow ... low risk," he said.
Low-risk means you have an 80-percent chance of holding onto your hair. High risk means a 60 percent chance of severe hair loss by 40.
Tom's 15-year-old son Eric is up next.
"I can see here that I'm high risk. It's a bit shocking to find out at such a young age," said Eric.
One-hundred-million Americans have hair loss- about 60 million are men and 40 million are women. Doctors say the gene test can be empowering.
"This just gives another piece of information and then you decide with your doctor what you want to do," said Alan Bauman, MD, Board-Certified Hair Restoration Physician.
Tom's low risk, but will keep getting hair preservation therapy. But high-risk Eric isn't worried - yet.
"I don't really care, like, right now. It's not of that much importance, because I have a full head of hair and it doesn't really matter that much," he said.
But he admits his opinions may change in the future.
