Using finasteride for hair loss is like shooting at sparrows with cannons.
Using finasteride for hair loss is like shooting at sparrows with cannons. The drug.…blocks not only the super hormone but also other hormones that affect thinking and psyche, mood and emotions.

We wouldn’t recommend that any man take [finasteride], especially not young men.
We are certainly very cautious, because we see the side effects. We wouldn’t recommend that any man take [finasteride], especially not young men. The longer they take it, the greater the risk of experiencing persistent side effects, including after they’ve stopped.

Blocking 5alpha-reductase by finasteride treatment may have broad consequences for the nervous system.
[W]e have evaluated in male rats the effects of a subchronic treatment with low doses of finasteride.…and the consequences of its withdrawal.…on neuroactive steroid levels…. Interestingly, at the withdrawal, some of these effects persisted, and different changes in neuroactive steroid levels, and in the expression of receptors, were also detected. Altogether these findings suggest that the block of the enzyme 5alpha-reductase by finasteride treatment may have broad consequences for the nervous system.
