Sources & verification

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

Editorial note: VERIFIED TIER 1, current. Independent authority-body confirmation: BOTH principals in ISHRS — Neidel doctor/37564 and Leonhardt doctor/619737 (both current). CORRECTION: Neidel is an ISHRS ASSOCIATE Member, not a Fellow — earlier framing implying Fellow-grade is downgraded here. Leonhardt is a Full Member (joined 2017), confirmed as a current second principal (with the practice since 2000) and additionally a member of Verband Deutscher Haarchirurgen e.V. Lars Dannenberg (dermatologist, joined 2025) kept as a third, lower-confidence principal (clinic-site only). Contact [email protected] + 0211-3230261 + Königsallee 30 confirmed live from hairdoc.de/kontakt (not guessed). Doctor photos remain PAGE URLs — direct <img src> .jpg still needs extraction before publishing, so photo confidence held at medium and no photo object emitted in the photos[] archive.
