I'm really curious what the long term effects of finasteride use will be or if there are side effects from withdrawl. So many people I know use it and this is the first I've read of this side effect, so it must be relatively understudied. I guess the silver lining with so many people testing out a drug like this is that it makes it easier to look at more rare side effects with a larger sample size. Sometimes I think if there's an actual perfectly safe cure for baldness out there, you'd at least see rich people like the British Royal Family or LeBron James using it.

Pregnenolone and DIM supplementation might help there. Though post-finasteride syndrome is likely a complex beast and very individualized.

The most common reason I've seen speculated is the neurosteroids that 5-alpha reductase is involved in, allopregnanole and isopregnanolone.
