What is the best cure for thinning hair for men?

Start with simple. Rogaine then you can add in propecia (finasteride).
2 great options. The first thing you can do immediately is buy Minoxidil otc 5% and use twice daily. I find that more people prefer the foam over the liquid as it isn't as irritating to the scalp. At about 9 months, you should notice thickening of the caliber of each hair. You can also go to your dermatologist for an rx for propecia (finasteride). There are some potential side effects, uncommon, that he or she will discuss.
