You don't need a prescription for minoxidil in Australia. You can buy "Regaine" at the pharmacy. However, it's three times more expensive than ordering it from the USA, because everything is overpriced in this isolated backwater. You can also buy 1% or 2% nizoral at the pharmacy.
For finasteride, the first doctor I went to was an idiot. He said they would first need to order expensive blood tests to see that i wasn't losing hair due to deficiencies. Then, it doesn't matter anyway because baldness is genetic. He said in studies, one third of people benefit from finasteride, one third show no difference, and one third improve, so it's a waste of time. He also said finasteride is for prostate cancer, it's a 5mg pill, whereas propecia is the name used for baldness. He said some dermatologists recommend minoxidil instead.
Second doctor I went to was like "yeah, you have temple recession", he wrote the prescription for finasteride 5mg and said i should buy a pill cutter. He said side effects are rare at the lower doses.
