The only thing I have ever found to inhibit hair loss while on a cycle and off is spironolactone. Finasteride didn't do shit for me, and neither did minoxidil. According to some hair loss sites I've checked, nizoral shapoo can also help. The 1% ketoconazol can be bought OTC here, but I buy the 2% in TJ for half the price. I've only been using it for about a month, but combined with the spiro, my hair loss seems to have stopped.
