The operation was winter. The drain is spring. That lag is classic telogen, not proof the surgeon “killed DHT follicles” in a weekend. Transplant shock is a related but separate HairBase file. This is not medical advice.
Telogen effluvium follows major illness and surgery the way it follows high fever — a delayed club-hair shed of cycling follicles, usually without scarring. The American Academy of Dermatology’s shedding pages are a calendar and a scalp exam, not a biotin megadose protocol. Anaesthesia, caloric dips, iron loss, and new medicines can share the clock. Patterned miniaturization can still sit underneath. This page will not invent an ASA-score-to-strand PMID and is not medical advice.
If you had a hair transplant, ordinary shock loss of native and grafted hairs is discussed on other HairBase pages — it is not a refund coupon and not proof of malpractice by itself. Do not restart topical minoxidil on a fresh wound because a forum said so; that is a surgeon-and-label conversation (there is a “stop minoxidil before surgery” page). Oral 5-ARIs have their own perioperative handling with the prescriber. Photograph the same part. Painful clumps, pus, or a shiny stripe after tight head straps in the operating theatre can be pressure alopecia — see a dermatologist.
Emergency surgery: tell the team you use minoxidil (topical versus oral) rather than delaying care for an internet checklist. Pregnancy-related procedures still need obstetric input on hair drugs. This is not medical advice.

FAQ
How long after surgery does shedding start?
Often about two to three months, telogen timing. Individual clocks vary. This page is not your discharge calendar.
Will the hair grow back?
Classic telogen often recovers over months if the stress has passed. Coexisting pattern loss and transplant shock need their own plans. A clinician separates them.
Should I start finasteride the week I leave hospital?
No automatic start. 5-ARIs are labelled male-pattern drugs with pregnancy rules, not surgical antidotes. Ask the teams who know your operation and prescriptions.
Is this the same as stopping minoxidil before surgery?
Different files. Holding a labelled drug for a procedure is a clinician timing question. Post-op telogen is a stress-clock question. Do not mix the two into a double-up protocol.
