Methodology Validation: Correlating Adherent Scalp Flaking Score (ASFS) With Phototrichogram for Scalp Dandruff Evaluation in Adult Subjects.

Introduction Scalp dandruff is a common dermatological condition characterized by flaking and itching of the scalp, affecting a significant portion of the population. Effective assessment methods are crucial for evaluating treatment outcomes. This study aimed to establish the reliability and correlation of three assessment techniques: Adherent Scalp Flaking Score (ASFS), phototrichogram using CASLite Nova, and the 60-second hair combing test.
