What we checked, where we read it, and on what date: the working notes behind the figures on this site.
Every figure is sourced and dated on its own page.
Korea runs a registration scheme for clinics that treat recruited foreign patients, the register is public and searchable in English, and a registered hair clinic must hold at least one board-certified specialist per treating department plus malpractice liability cover.
Istanbul's median advertised entry package is $2,720 all-in against $4,865–11,780 for surgery alone in Seoul, and the two markets differ by statute on who may legally hold the instrument.
One Seoul clinic's statutory non-covered fee schedule prices its largest band, 4,500 hairs and above or roughly 2,250 grafts and above, at $4,865–11,780 for surgery alone.
A Seoul fee schedule's own footnote states that one follicle carries an average of two hairs for non-incision extraction, so a Korean headline number is roughly double the graft count you are comparing it against.
Each of these twelve questions exists because a statute, a regulation, an audited filing or a peer-reviewed paper says the answer varies, from Turkey's one-physician-to-five-rooms clause to crusts that clear at 7–10 days.
Of the six markets this site tracks, only Korea prohibits delegating the operation to non-licensed hands outright; Turkey's own 2023 regulation reserves just the channel-opening step to a certified physician and lets one physician cover up to five rooms at once.
