Why nothing works in weeks
Hair grows in cycles measured in months, and treatment works by shifting follicles between phases of that cycle. Any product promising visible regrowth in two weeks is selling against biology.
Realistic timelines, per the clinical literature: reduced shedding at roughly 3 months, visible change closer to 6, full assessment at 12. That's not a hedge — it's how follicles work.
What each medication does
Finasteride lowers DHT, the hormone that miniaturizes follicles in male pattern loss — it defends the hair you have. Across long-term studies cited in its FDA labeling, most men maintained or improved hair counts over multi-year follow-up.
Minoxidil works differently: it improves blood flow around the follicle and extends the growth phase. The two are often combined because they attack different sides of the problem — when a provider determines both are appropriate.
The shedding phase, honestly
Some people shed more in the first weeks of treatment. Counterintuitively, that's often a good sign: old resting hairs are being pushed out by follicles re-entering the growth phase. Providers who don't warn you about this set you up to quit at exactly the wrong moment.
When online treatment is the wrong tool
Patchy loss, sudden shedding, scalp pain or scarring point to different diagnoses — autoimmune, thyroid, dermatologic — that need in-person eyes. Our intake screens for these and says so plainly rather than shipping pattern-loss medication at a problem it can't fix.
