side effects on the internet are blown out of proportion. cmon people here believe earth is flat... there's literally no complaining about dutasteride on comparison and that's a way stronger drug than finasteride is. look at askapatient.com nobody's complaining about finasteride, just propecia (merck, big pharma that owned the brand till it went generic 5-10 years ago), cause that's where the money in lawsuits are, american complain culture... than you look at people complaining about libido and they're all like 70+ rofl
believing that everyone that takes finasteride gets chemically castrated, drug that's been on a market for over 20 years is on par with anti-vaxers. trans folk take spironolactone, estrogen etc. and still have functioning d**s.
if you do want to stay on the safest side microdose, some people take 0.25 of a tablet with same results.
if you really dont want to risk being in that few percent that complain
only option is minoxidil and dermarolling (might be quicker for regrowth) but doesn't tackle the cause of hairloss, any other treatments are snake oil though and would only work if your hairloss is not really genetic induced but rather stress or vitamin mineral deficencies.
ru58841 might be another option if you can get your hands on it. some people respond to it very well. ru binds to receptors in your hair follicles, stopping dht from doing that, but it's not an easily available treatment so it will cost more (make sure it's not illegal in your country).
finasteride lowers your dht levels, depending on how sensitive your follicles are/agressive hairloss(when it started) it will either stop, slow down, or reverse some of balding.
minoxidil will improve blood/nutrient circulation to your folllicles, with same effects (possible halt, slow down, regrowth). but its really like steroids to your hair follicles without tackling main cause - dht.
dermarolling/wounding - induces body's naturural response to heal the wounded area, sending growth hormones to the area thus aiding the follicles.
sorry, but these are your best options. for a lot of people they work totally fine for decade+.
hair transplants don't tackle the cause of hairloss. and any surgeon that says you're ok with not taking finasteride just wants you back in next 2+ years for an expensive touch up.
