    In the 2011 study, researchers examined the distribution of melanin on the scalp of 43 fair-skinned Caucasian men with androgenic alopecia using the Visioscan® camera with ULEV and the Visioface® Quick device. They found a mottled subclinical melanoderma (MSM) pattern of hypermelanosis, characterized by smaller spots at hair follicle openings and larger spots in interfollicular areas, with a few hypomelanotic spots also present. The study concluded that this MSM pattern might provide insights into the patterned pathobiology of melanocytes and could be related to photo-induced skin diseases, resembling widespread PUVA-induced lentiginosis.
