Fear of losing hair is the one most reason for the hair fall in both men and women. So by the introduction of Provillus you can just ignore the fear of losing it. Provillus really works great for men in any age group. They show the difference in the hair within six to eight weeks. If not shown up, then we have to increase the dosage. Provillus for men should not be used by women as they are made for the tissues related to men hair. The causes for the hair loss will be different for men and women such as the cause for hair loss in men are related to the production of DHT in men.
