Summary Seborrhoeic dermatitis and dandruff are common scalp conditions. In this study, we set out to explore a new method for rating both the severity of the scalp condition and the efficacy of scalp‐care compounds. Scalp flakiness was sampled for 40 volunteers using adhesive‐coated clear discs, with image analysis used to quantify the specular light reflectance (SLR) of the flakes Two ultraviolet (UV)‐emitting charge‐coupled device cameras (Visioscan VC98 and Visiopor PP34) were used. SLR clearly highlighted the flakiness with high contrast against a black background, and the recorded appearance could be conveniently submitted to the image‐analysis system for quantification. In conclusion, SLR under UV illumination highlights scalp flakiness, allowing objective measurements.
