Propecia is a prescription medication that comes in pill form, and is to be ingested once daily. Studies show that 60% of men who take Propecia will see a decrease in hair loss, and approximately 40% will grow more hair – especially on top of the scalp. Recent studies demonstrate that the sooner Propecia is begun, the greater the long-term results. Propecia is indicated for men only.
Rogaine is an over-the-counter solution that is applied to the scalp twice a day. It's the best option currently available for female hair loss, and it works well in conjunction with Propecia to slow and reverse male hair loss.
