Which is the best method?

I'm looking to delay hair loss as much as possible. Of the products out there which does the best job of this? Propecia, Avodart or Proscar? If I'm using one of these is it a waste of money to use rogaine as well. Please advise.

Please don't use drugs like proscar or avodart. They are among some of the most dangerous drugs on the prescription market. They can induce secondary hypogonadism, hypothyroidism and adrenal fatigue if taken for long enough and cannot   always give hair regrowth. These drugs can lead to a lifetime of impotence and loss of libido due to them inhibiting DHT which is essential for normal male characteristics. Do a google search to find out more.
