Interesting! Thank you for the input. Yes I really was just curious from person insight or research if dutasteride over a period of time may need switched or higher dosage as well as oral minox. Nothing is truly permanent but if they work for 20-30 years I guess that’s all you can ask from them. But also maybe with time from ages 40-80 your dht isn’t as high so those are not needed as much as hair loss in 20s? Who knows
