It might work, but expensive invasive injections every 3 months forever? No thanks. Sounds a lot worse than finasteride to me. Imagine the price gouging they would do on that. They could raise the price quadruple 12 months after you started, and you have to keep going back to the well no matter what to maintain that.
I guess a topical dutasteride injection that helped maintain with no or minimal sides would be good, but id much rather it be a topical someone buys vs injections like this.
IF it "worked", (ambiguous phrase that has a different meaning to everyone), I would pay quite a bit and def go 4 times a year to have it done. That's not that bad. Hell, people go get Botox just as frequently, and getting shots in your face seems worse than the scalp.
