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.

How Many Grafts Do I Need? A Calculator-First Guide

Name: HairArchitect AI
Author: HairArchitect AI

Step-by-step: measure recipient area, pick target density, understand donor limits, and use graft calculators as a conversation starter with your surgeon.

TL;DR

Graft need equals recipient area (cm²) × target density (grafts/cm²), capped by safe donor supply. Online calculators give a range; only an in-person donor assessment can finalize the number.

Step 1 — Define the recipient zone

Draw the hairline, temples, and any mid-scalp or crown zones you are discussing. Mixing zones is the main reason two calculators return different totals.

Step 2 — Pick a realistic density target

Typical planning densities (illustrative—not prescriptions)

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

Step 3 — Check donor supply

A calculator may say 3,500 grafts while your donor safely supports 2,200. Hair caliber, scalp laxity, and prior surgery change the ceiling. Ask: “What is my safe one-pass yield?”

Norwood-Hamilton staging helps estimate recipient area and coverage needs—it is a clinical classification tool, not a graft prescription. (PubMed — Norwood-Hamilton scale (male pattern baldness classification))

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.
