Hi Andy,
your best BET are what are termed on this forum as the big 3, Propecia, Minoxidil and Nizoral shampoo.
Then, if you decide, its a case of try them for at least a year and you may experience maintenance and a halt to hair loss or even some regrowth.
There is also a chance no improvement will be made.
Unfortunately no one can tell you if these medications will work for you, only time can tell.
I would recommend that you research these three and base any decisions off the back of this.
