The Duplan Method™
Framework overview
Diagnose Before You Touch™
Every healthy hair journey begins by understanding the strand before choosing products, techniques, or styles.
Every healthy hair journey begins by understanding the strand. Before any product, technique, or style is chosen, The Duplan Method™ teaches a structured strand-aware assessment — diameter, density, porosity, elasticity, and scalp condition. The complete assessment framework is available only through certification.
The complete methodology, tools, and implementation details for this area are taught inside the Duplan Method™ certification program. This page is a professional overview, not the full curriculum.
