I am treating my hair loss with Propecia Generic Finasteride.
I'm 40 and have a hair loss problem since last 5 yrs. I tried many drugs, shampoos, gels and creams and finally I settled for Propecia Finasteride. Propecia is the best medicine for hair loss. It certainly has some side effects and these side effects disappear as our body gets used to the medication. I'm using Propecia for year and half. I too had some side effects like decreasing sexual desire in the beginning and as my body got used to it slowly, most of the side effects disappeared. As per my experience Propecia is long term medication and it should be continued at least for six months.
After year and a half, today 80% of my receding hairline disappeared with negligible side effects.
