If you're looking around the family table at your balding father your long-ago bald grandfather and wondering if you're going to follow suit, scientists have a quick and easy way for you to predict the future of your hairline -- the 60-second hair count.

During a recent study, 60 men without current evidence of balding. The men washed their hair for three consecutive days using Neutrogena T/Sal shampoo. On the fourth day they were instructed to comb their hair over a towel. Participants then counted the hairs that were lost. They repeated the comb-and-count procedure for two more days. The whole routine was repeated six months later.

So if you want to gauge your hair loss, try your own 60-second hair count study once a month. Record the data and discuss it with your dermatologist if you're seeing an increase in hair loss.
