TLDR The methods tested are reliable for assessing dandruff reduction.
This study involving 12 adult subjects with mild to moderate dandruff validated the reliability and correlation of three assessment techniques: Adherent Scalp Flaking Score (ASFS), phototrichogram using CASLite Nova, and the 60-second hair combing test. Post-hair wash, significant reductions in dandruff were observed across all methods, with ASFS showing a 71.40% reduction. Phototrichogram analysis indicated that 60.42% of scalp zones were in normal condition post-wash, and the hair combing test showed a decrease in non-adherent flakes. The study confirmed significant correlations between ASFS and phototrichogram results, with substantial inter-evaluator and inter-operator reliability. These findings support the use of these methods in clinical settings for assessing scalp dandruff, emphasizing the need for comprehensive training to ensure accurate results.
