Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.
Finasteride was intentionally developed to treat BPH and later approved for male pattern baldness (MPB) due to its 5AR inhibition effects. The delay in MPB approval was due to concerns about off-label use for female hirsutism and the prioritization of treating a more debilitating condition.
Finasteride is discussed as a hair loss treatment with benefits like reduced prostate enlargement and skin aging, but it is not seen as a "fountain of youth." Users report mixed experiences, including side effects like decreased libido and dry eyes.
A 20-year-old experiencing hair shedding after starting oral finasteride is advised to continue treatment and consider adding topical minoxidil. Shedding is normal, and patience is needed for hair regrowth.
The conversation is about hair loss treatments, with users recommending finasteride and minoxidil as effective solutions. Some users report side effects, but overall, the consensus is to use these treatments rather than waiting for a cure.
