The Finasteride Crisis: A 20-Year Failure That Should Terrify Every Man Considering Hair Loss Treatment
A devastating new study just dropped in the Journal of Clinical Psychiatry that should make every man currently taking or considering finasteride for hair loss stop in their tracks. As a holistic systems health physician, I've been warning patients about this drug for years, but even I'm stunned by the magnitude of harm revealed in this systematic review.
The Numbers Nobody Wanted You to See
Dr. Mayer Brezis's analysis reveals a public health catastrophe hidden in plain sight: Over 20 years worldwide, hundreds of thousands may have endured depression, and hundreds may have died by suicide from a medication prescribed for the cosmetic indication of hair loss.
What the Research Actually Shows
The evidence is overwhelming and consistent. Between 2017 and 2023, 4 independent analyses of adverse event reporting systems and 4 studies using data mining of healthcare records indicated a significant increase in the risk for depression, anxiety, and/or suicidal behavior with the use of finasteride.
Here's what makes this alarming:
Studies show significantly higher rates of self-harm (HR 1.9) and depression (HR 1.9)
Significantly increased signals for suicide ideation (reporting odds ratio 3-5) and completed suicide (ROR 5-9)
One French study found significantly higher self-harm rate (HR 3.1) and suicide (HR 2.7) if prior history of mood disorders
These neuropsychiatric reactions often last long after medication discontinuation and are sometimes severe enough to lead to suicide.
The Biological Smoking Gun
This isn't just correlation - we understand the mechanism. Finasteride, by inhibiting 5α-reductase, reduces the synthesis of neurosteroids, brain hormones that regulate mood, particularly allopregnanolone. Think of it as chemically castrating your brain's ability to maintain emotional stability.
The Cover-Up: A Two-Decade Delay in Recognition
Here's where it gets truly infuriating. Concerns about depression from finasteride were raised in studies as early as 2002, but the FDA didn't recognize mental adverse reactions until 2011 for depression and 2022 for suicidality. The European Medicines Agency only acknowledged finasteride can cause suicide in 2025.
Why the delay? The manufacturer's failure to perform and publish simple pharmacovigilance studies using database analyses and regulators' failure to request such studies from the manufacturer.
The paper reveals something even more disturbing: By 2011, only 18 suicides had been reported to the FDA, while 6,440-12,880 were expected for 10 to 20 years of observation in a population of 4.6 million finasteride users. This represents a staggering level of underreporting.
If you're considering finasteride:
Just don't - the risk-benefit ratio – not worth it!
Address root causes - investigate thyroid function, nutrient deficiencies, and stress management
