I'm not gonna be like everyone else on here and call you dumb for starting dutasteride at such a young age. it's not without its risks but i understand why you did it.
what i will call you out on is that i think you're very seriously overestimating your hair loss, seriously. you're going full doom-sayer saying there's no hope for you and this and that. dude, you're like a NW1 right now.. why are you so worried? dutasteride blocks over 99% of DHT, seriously it is literally almost impossible to lose hair while on dutasteride. you're not losing any wars if you're on dutasteride, so just calm down and stop thinking about your hair loss so much.
i think you have a case of body dysmorphic disorder or something in all seriousness. i have something similar so i know what its like to worry incessantly about your appearance.. maybe you should consider seeking psychiatric help.
