What is the difference between surgical advancement and transplant grafting?

Surgical hairline advancement involves a single incision at the existing hairline, physically moving the scalp forward to reduce forehead height by 1–3 cm. It delivers immediate results with a thin scar along the new hairline. Transplant grafting uses FUE or DHI follicular units to create a lower hairline without surgery, can achieve 2–5 cm of lowering, and leaves no linear scar — though full results take 12–18 months to mature.

How accurate is the hairline lowering simulation?

The simulator renders follicular units using Poisson-disk distribution at clinically realistic graft densities (25–50 grafts/cm²), with hairline curvature modelled from your uploaded photo. Actual results depend on individual scalp laxity, donor density, and surgical technique. Always consult a board-certified surgeon before making treatment decisions.

How many grafts are typically needed?

Most hairline lowering procedures via transplant require 1,500–3,000 grafts depending on the amount of lowering desired, the hairline shape selected, and whether temple triangle filling is included. The simulator lets you adjust graft count from 500 to 3,500 to explore different coverage levels.

Is hairline lowering popular in Korea?

Yes — hairline lowering (이마축소술) is one of the most requested hair procedures in Korea, where a smaller, rounder forehead is a widely held aesthetic preference. The Korean bell-curve hairline shape is included as a default option in our simulator for this reason.

What does the post-op timeline show?

The timeline slider models the expected growth phase: minimal visible growth in months 1–3 (shock loss phase), early fine hairs from months 4–6, noticeable density by months 7–9, approximately 85% of final result by 12 months, and full maturation by 18 months.

Overview

Hairline lowering addresses a high or disproportionately large forehead. Two primary methods exist: surgical hairline advancement involves an incision at the existing hairline, pulling the scalp forward, and excising excess forehead skin — lowering by 1–3cm with a thin scar along the hairline. Hairline transplant uses FUE/DHI grafts to create a lower hairline without surgery, achieving 2–5cm of lowering with 1,500–3,000+ grafts.

This procedure is extremely popular in Korea where smaller foreheads are culturally preferred. It’s often combined with hair transplant for temple corner filling. Ideal forehead height is 5–6cm for women and 6–7cm for men, measured from the brow to the hairline at center.

Our simulator shows dramatic before/after forehead proportion changes with Korean-style bell curve hairline design, temple triangle fill options, and forehead measurement overlay.
