Sources & verification

Last verified 2026-07-12 · placed by verification, never by payment.

Editorial note: DOWNGRADED to tier 2 (from candidate tier 1): the named surgeon Dr. Chronis is NOT listed in any authority body (ISHRS/IAHRS/ABHRS checked — absent), so the tier-1 bar (authority-body-verified principal) is not met. Otherwise strong: single named physician performs the whole procedure, current (dedicated live surgeon page), Trustpilot 4.9/~72, plus an independent Hair Restoration Network patient forum thread and the Danish comparison site hartransplantation.dk. Doctor photo kept (from own surgeon page, high confidence). Email confirmed on site.
