Validation and clinical relevance of a novel scalp coverage scoring method

Background/aims: Distinctive patterns of defective scalp skin coverage or alopecia have been identified by clinicians but do not help measuring the dynamics of hair changes over time. Hence, we conceived the scalp coverage scoring (SCS) method that integrates cumulative changes of hair growth or loss. In this paper, we report the results of validation studies demonstrating that the SCS can be applied in real time in the clinic or on global photographs for evaluating the severity of androgenetic alopecia (AGA) of male subjects and for monitoring changes over time.
