Ten readings, one drug
Each page below takes one question people actually ask about finasteride and answers it from the documents rather than from the forums — with the date on every one. None of them tells you to take anything, and none of them will give you a dose.
How finasteride works on DHT, and what else that enzyme does
The mechanism is simple enough to draw. The interesting part is what else 5-alpha-reductase is doing, because that is where every argument about side effects starts.
Sep 24, 2026Finasteride vs minoxidil: not the same kind of decision
One is a prescription tablet acting on a hormone pathway; the other is an over-the-counter topical that does not. Comparing them on effectiveness alone misses the point.
Sep 23, 2026Finasteride, pregnancy exposure and male fertility
The least ambiguous section of the whole label, and the one most often skipped: who must not handle the tablets, what the semen study found, and what recovers.
Sep 22, 2026What happens when you stop taking finasteride
The label answers the hair question in one sentence and the trials show the shape of it. The other question — symptoms that do not stop — is answered far less cleanly.
Sep 21, 2026Does finasteride regrow hair, or does it hold the line?
The trial data answers this precisely, and the answer is mostly the second one. Here are the counts, the photograph ratings and the reason the placebo column matters most.
Sep 20, 2026Finasteride and minoxidil together: two drugs, two regulators, one scalp
They work by unrelated mechanisms and sit in different regulatory categories. What combining them changes most is your ability to tell which one caused anything.
Sep 19, 2026Finasteride vs dutasteride, and what off-label really means
Dutasteride blocks both forms of the enzyme instead of mostly one. In the US, UK and EU it holds no hair-loss licence at all — in Japan it has held one since 2015.
Sep 18, 2026Topical finasteride: the same drug, a different legal object
In the US there is no approved topical finasteride, so what is sold is compounded and unassessed. In parts of the EU a spray is licensed. The difference is not cosmetic.
Sep 16, 2026The regulator record on finasteride, in order and dated
Eight documents from four regulators over thirty-four years. What each one says, what it changed, and why the sequence matters more than any single quote from it.
Sep 14, 2026Post-finasteride syndrome: what is and is not known
A contested name for a documented set of symptoms. Here is what each regulator has actually written, where they agree, and the three questions none of them can answer.
