A calculator has been launched online which can predict when you are likely to lose all your hair and how you will look when you turn bald.
The dating device comes courtesy of Dr Adolf Klenk, a hair loss specialist associated with the Alpecin research institute in Germany.
His calculator asks the reader a series of questions and then, based on the answers given, predicts the likelihood of possible balding and the approximate age at which it may happen.
And if you want to see what you would look like with no hair then, upload a picture to get the answer.
The most common form of hair loss is androgenic alopecia, which is genetic.
"It's not a disease so there isn't a cure," Sky News quoted Alpecin spokesman Rick Guttridge as saying.
"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," Guttridge added.
