Most of today’s medicines for treating hair loss have limited effectiveness. Currently, we don’t have a complete understanding of exactly why certain diseases cause hair loss. In many cases, we treat the symptoms, but not the causes of diseases. And often our ability to treat symptoms has limited effectiveness.

Today’s medications prescribed to counteract androgenetic alopecia (genetic pattern hair loss), require ongoing use for the benefits of treatment to continue, and these medications have only a limited effect on some patients. And the cost of drugs that must be taken continuously adds up to a large lifetime expense. In the future, as physicians and scientists gain a better understanding of how the normal hair growth cycle is controlled, and how various disease conditions affect hair growth, new medicines will be developed that more effectively target the cause of the hair loss, and cause fewer side effects as a result
