A 90-count bottle is a camera interval
Kaufman's 1998 randomised men did not get graded in a bathroom bulb at refill one. They sat under a photography protocol that fixed distance, part, and light.
A 90-count 1 mg bottle matches how US pharmacies actually dispense Propecia. It also matches the first planned photo pair many clinics book - and that is where patients panic. Day 90 is early for a follicle that spends months in telogen after a DHT drop.
Scalp DHT falls within weeks. Visible density does not. The packages that still get cited printed hair counts and investigator globals at 6 and 12 months, with 24-month extensions. Judging the file at the first 90-count refill is reading the wrong row.
Dr. Liam Hartwell keeps this page on photography discipline. He does not write your prescription from a study desk.
Bring the same camera, the same hour, and a wet-part you can repeat. A phone selfie from a different window is not a data point.
Insurance 90-count fills create a false deadline. The payer's bottle size is a logistics chip. The Kaufman clock is a year. Do not let a refill date masquerade as an efficacy endpoint.
Global photographs versus counted hairs in a circle
Olsen-style global photographs grade the whole vertex or mid-scalp the way a stranger would see you. Macro hair counts punch a one-inch circle, clip, and tally. The 1 mg packages used both. Patients only remember the global shot because that is what they can copy at home.
Hair-count grids catch small gains the eye misses. Global photos catch whether those gains matter in a room. A file that brags about 80 extra hairs in a circle and still looks thin under overhead light is not a contradiction. It is two instruments.
Dermoscopy and trichoscopy now sit beside those older cameras. They help exclude telogen effluvium, thyroid, and iron before anyone starts a 90-count bottle. They do not replace the 12-month global pair the label trials actually used as the beauty contest.
Minoxidil foam in the same frame confounds both instruments. If you add a topical mid-course, write the date on the photo card or you will credit the wrong molecule.
Macrophotographs need a tattooed or inked circle if you want countable hairs. Moving the circle between visits invents growth. Home phones cannot do that grid. They can only do honest globals.
Sexual-event ink on the 1 mg label trials
Label tables put sexual adverse events in the low single digits on 1 mg, a point or two above placebo. Real-world surveys print higher. Both can be true: trials exclude, surveys amplify, and some men are in the tail.
Post-finasteride discussion exists because a subset reports symptoms after stop. Causality is contested; the counseling duty is not. Tell men the trial percentages and the existence of the longer-tail reports before the first 90-count, not after week six.
PDE5 tablets for a separate erectile complaint sit on another line - start at the Cialis 2.5 daily formulary if that is the actual question. Do not treat a new 1 mg start and a new ED tablet as one experiment without saying so on the card.
PSA falls on finasteride. Anyone watching prostate numbers needs the multiplier, not a raw comparison to last year's value.
Breast tenderness appears in a small trial slice. New lumps are an exam, not a photography footnote. Gynecomastia is uncommon on 1 mg and still deserves a call rather than a forum thread.
Month-three shed that is not treatment failure
Some men shed more in the first 8 to 12 weeks as miniaturised hairs synchronise. A 90-day photo pair taken at the bottom of that shed looks like harm. The 12-month pair in the same light often looks like the packages.
True failure is continued loss at 12 months on documented daily 1 mg, after you have excluded iron, thyroid, and a crash diet. True failure is not a thinner-feeling shower at week ten.
Placebo arms lost hair. That fact is what makes the 1 mg vertex hold meaningful. A man who compares himself only to last year's wedding photo, not to the untreated trajectory, will always feel the drug 'did nothing.'
If sexual symptoms or mood changes appear, that is a stop-and-call column - not a reason to invent a new photography schedule. See the safety ink below and the ledger disclaimer.
Crash dieting in the same quarter as the 1 mg start produces a telogen wave the camera will blame on the tablet. Write the diet dates on the photo card. Iron and thyroid belong on the same pre-start blotter.
Lighting cheats that ruin a 90-day pair
Overhead bathroom yellow versus noon window white will 'grow' or 'lose' hair that never moved. Wet hair looks darker and thicker. A tighter part hides the vertex. Clinics that run real photo rooms lock those variables. Phone pairs at home almost never do.
Print a cheap protocol: same phone, same distance marked on the floor, same hour, hair washed the night before, no product, flash off, two angles. If you cannot repeat the setup, do not use the pair to decide a stop.
A 90-count refill is a good calendar reminder to shoot. It is a bad calendar reminder to quit. The packages that still matter printed the beauty contest later.
Keep the first pair even if it looks ugly. You cannot invent a baseline in month eight.
Flash-on phone shots bleach the part line and invent density. Turn the flash off. If the room is too dark, change the hour, not the flash.
The hairline camera lags the crown
Frontal recession responded less, and slower, than vertex in the same 1 mg programme. Temples that have been bare for a decade do not photograph like a thinning crown that still has miniaturised hairs to rescue.
A day-90 frontal pair is almost designed to disappoint. The camera is honest. The timeline is wrong. Book the hairline shot at 6 and 12 months if that is the zone you care about, and say so before the first 90-count so nobody promises a temple from a vertex paper.
Norwood class and baseline density belong on the card. A man who is already shining at the front is asking a 5-alpha-reductase inhibitor to resurrect empty ostia. Photography will document that limit. It will not negotiate it.
Transplant consults after a year of documented 1 mg use are a different ledger. The photos still help the surgeon. They are not a failure stamp if the crown held and the hairline did not grow forward.
Norwood VI vertex shine is a rescue limit. Empty ostia do not photograph into density on 1 mg. Baseline class belongs on the card so nobody promises a teenage part from a late-pattern scalp.
Vertex numbers Kaufman still gets cited for
Kaufman 1998 randomised 1,553 men with vertex pattern loss to finasteride 1 mg or placebo for a year. The treated circle gained on the order of 80-plus hairs; placebo lost hairs. Investigator globals called about half the treated men improved and most of the rest stable. Placebo mostly worsened.
That is a hold-the-line drug with a chance of visible thicken, not a transplant in a tablet. Men who wanted a teenage hairline from a 90-count bottle were never the population.
Leyden's companion work and the five-year extensions said the vertex advantage persisted if the tablet continued. Stop, and the DHT-driven miniaturisation resumes. There is no stored 'credit' from three quiet months.
Women of childbearing potential are not in this photography file. Finasteride 1 mg is contraindicated in pregnancy because of hypospadias risk in a male fetus. This page does not improvise a female protocol.
Five-year extension tables still get photocopied in clinic teaching files because the vertex hold persisted only while the tablet continued. That is the long photography answer to 'can I stop after the 90-count looks fine.'
Keep shooting; do not retire the 1 mg early
THL-S10 files Propecia 1 mg as a photography problem first. Vertex counts from Kaufman still hold. Frontal shots lag. Day 90 is a checkpoint on a 90-count bottle, not a verdict.
Same light, same part, same camera. If the 12-month pair is worse on documented daily 1 mg, that is a conversation. If the 90-day pair is moodier than the wedding album, that is noise.
This desk does not dispense. Your own clinician writes the card after you bring the photos, not the other way around.
Print the 90-count as a reminder to shoot, not as permission to quit. The packages that still matter graded the crown later than the first refill.
Keep a paper folder or a locked album. Cloud cameras that auto-enhance portraits will 'grow' hair the follicle did not grow. Turn the filters off before you judge a 1 mg year.
A 90-count bottle that sits in a gym bag missed half its days. Photography cannot rescue a half-taken year. Count the blisters before you count the hairs.
Talk with your own clinician or pharmacist before you change a tablet or a dose. Open the ledger disclaimer.
