Assist to Hairline Device (AHD) – How to Use?

Introduction

This demonstration shows how to accurately measure and design a patient’s hairline using the AHDR tool. Proper placement is key for achieving a natural, age-appropriate look tailored to the patient’s level of hair loss, ethnicity, and desired style.

In this video demonstration of the AHD, we demonstrate the use of this tool on a patient.

Procedure Overview

Key steps from the demonstration:

• Initial Positioning:
  • Place the AHDR so that the zero mark is centered between the patient’s eyes.
  • Measure vertically to determine hairline height.
• Hairline Height Guidelines:
  • In this example, the patient has a 10 cm hairline due to advanced hair loss (Class VI progressing to Class VII).
  • Caucasian patients: The lowest point is usually around 7 cm from the glabella. Lower (e.g., 6 cm) can make hair project outward unnaturally and appear thin.
  • Asian patients: Typically follow the 7 cm baseline across, dropping slightly at the temples to connect the design.
• Design Adjustments:
  • Avoid creating a “U-shaped” hairline.
  • Raise widow’s peaks by 0.5–1 cm for a balanced look in Caucasian designs.
