0.5mg every 3 days not enough fin? Increasing dosage

[Buddho]

After slowly tapering onto propecia, I spent a good 7-8 months on a dosage of 0.5mg every 3 days. When the shedding started around nomal time, I expected good things, my hair seemed to shed a lot though
But sadly I believe it has now returned and is a finer, more miniaturized group of hairs.
At the beginning of the month I increased my dosage to 0.25mg/day to hopefully stabilize my hormones if that was a problem with getting results. I have some very fine hair and others that still have decent pigment, this is why I believe my dosage might have been too low, only helping some hairs
Any opinions? I'm only 19 and my hairloss shouldn't be too bad to not have 0.25mg work for me
Thanks
