There is no single AAD-stamped “every 27 days” hair calendar on a Drug Facts panel. The clinician who examined you sets the next visit. Urgent patches, pain, pus, or a shiny bald band do not wait for a routine slot. This is not medical advice.
Topical minoxidil labels and the classic 1 mg finasteride hair story were built on trials that reported counts at months, not at day ten. The American Academy of Dermatology’s androgenetic pages still start with those labelled tools used as directed — which means you need time and the same lighting, not a weekly panic trim of the regimen. Follow-up is how a clinician checks irritation, sexual or mood side-effects on a 5-ARI, blood-pressure stories on oral minoxidil, and whether the pattern looks like telogen, areata, or scarring instead. This page will not publish a secret “optimal weeks between visits” PMID and is not medical advice.
Bring dated photos of the same part, same camera distance, dry hair, no fibers. Do not double foam because the appointment is in eight weeks. Do not handle crushed finasteride tablets in a pregnancy household while you wait. If you were started on a drug, ask that prescriber when they want you back — compounding pharmacies and telehealth shops are not interchangeable inserts. New round patches, rapid clumps, or scalp pain are now, not “at the six-month selfie.”
Children, pregnancy, and suspected scarring alopecias belong on a shorter fuse than a stable male-pattern check. This is not medical advice.

FAQ
Is every three months the official rule?
No official carton rule lives on this page. Many clinics review medical therapy on a months-scale. Your clinician names the date.
Can I skip follow-up if the drain looks better?
Drain hair is a bad biomarker. Pattern photos and side-effect questions still belong in clinic. Do not self-discharge a prescription drug.
What if I only use drugstore minoxidil?
OTC still has a label and an irritation story. A one-time dermatology exam helps if the part keeps widening. This is not a sales visit quota.
Should I book monthly trichoscopy?
Serial trichoscopy can help some practices track diameter diversity. Monthly is not a universal protocol. Ask the person holding the scope.
