Is Taking 0.2mg Every Three Days as Effective as 1mg Daily Finasteride?

Dear Doc,
Just read that 0.2mgs of finasteride taken once every three days is just as effective as 1mg daily at this site: hairloss-research.org

Is this bollocks?

That is just the opinion of one doctor, and I am also aware of similar opinions regarding low dose finasteride (though taken daily). I generally prescribe and recommend the standard 1mg treatment dosing to treat hair loss. From some research I have read, lower doses of finasteride 0.5mg and 0.25 mg will have an impact on DHT, but less of an effect can be expected from these lower doses.
