What is HairArchitect AI?

HairArchitect AI is a hair transplant planning and visualization app. It combines facial landmark analysis, hairline design tools, and graft estimates to help patients and clinics discuss surgical plans before a procedure.

Is HairArchitect AI a medical device?

No. HairArchitect AI is a planning and visualization tool. It does not diagnose conditions, prescribe treatment, or replace evaluation by a licensed physician or hair restoration surgeon.

How accurate is the HairArchitect simulation?

Simulations are designed for consultation communication, not outcome guarantees. Density, hair caliber, and surgical technique all affect real-world results. Final plans should always be confirmed with your surgeon.

Does it calculate graft counts?

Yes. Based on the designed recipient area and target density, HairArchitect AI provides graft estimates to support surgical planning. Estimates vary by clinic methodology and should be validated clinically.

How is my photo data handled?

Face and scalp photos are processed for planning features you choose. Our privacy policy describes retention, subprocessors, and your rights under GDPR, KVKK, and other applicable laws at hairarchitect.app/privacy.

TL;DR

Bedarf = Fläche (cm²) × Zieldichte, begrenzt durch Spender. Rechner liefern eine Spanne; erst Vor-Ort-Beurteilung finalisiert.

Schritt 1 — Empfängerzone definieren

Zeichnen Sie Haarlinie, Schläfen und mittleren Scalp/Vertex. Zonen-Mix ist Hauptgrund für unterschiedliche Summen.

Schritt 2 — Realistische Zieldichte

Typische Planungsdichten (illustrativ)

Zone	Common planning range (grafts/cm²)	Notes
Hairline	35–45	Single-hair units matter most
Mid-scalp	30–40	Blend with native density
Crown	25–35	Angle and swirl dominate perception

Schritt 3 — Spender prüfen

Ein Rechner kann 3.500 sagen, der Spender sicher nur 2.200. Haardicke, Laxität und Vor-OPs ändern die Obergrenze.

Norwood-Staging hilft Empfängerfläche einzuschätzen—klinisches Werkzeug, keine Graft-Vorschrift. (PubMed — Norwood-Hamilton scale (male pattern baldness classification))

35–45

Übliche Haarlinien-Dichte (Grafts/cm²) in Lehrmaterialien

30–40

Mid-Scalp-Dichten oft unter Haarlinienzielen

Donor

Sichere Spendermenge begrenzt Gesamtzahl unabhängig vom Rechner

Fachgesellschaften betonen individualisiertes Design statt Einheitsvorlagen—Gesichtsform, Alter und Spender zählen. (ISHRS — Glossary of Hair Restoration Terms)

Key takeaways

Use calculators to learn scale, not to shop for the highest number.
Bring your design and graft estimate to consult—HairArchitect AI exports a visual plan.
Finalize numbers only after donor mapping in person.

Is 4,000 grafts always better than 2,500?

No. Over-harvesting risks donor depletion. The right number matches goals, donor supply, and session plan.

Do grafts equal hairs?

No. One graft is usually a follicular unit with 1–4 hairs. Always ask about hair count, not just graft count.
