Dr. Adolf Klenk of the Alpecin research institute in Bielefeld said the baldness calculator uses a series of questions answered by users to calculate approximately when they will go bald, Sky News reported Friday.
The Web site also features a tool for men to upload pictures of themselves to see what they would look like with a bald head.
"It's not a disease so there isn't a cure," Alpecin spokesman Rick Guttridge said. "But what you can do is treat the condition, with medications to boost your hair."
"What we have discovered is testosterone has a negative effect on hair loss ... the testosterone makes the energy in each hair follicle run out sooner, so the more testosterone a person has the sooner they will burn out of their energy and the hair will drop out sooner," the spokesman said.
