TLDR Hair and nail disorders can cause changes in scalp pigmentation, especially with sun exposure and alopecia.
The document discussed the trichoscopic features of the normal dark scalp, highlighting a homogeneous brown honeycomb pigment network due to increased pigment density in the basal layer of the epidermis. This network was more pronounced in sun-exposed areas and differed between skin of color and white skin. In alopecic scalps, both nonscarring and scarring, the pigment network became more marked due to increased sun exposure. In advanced stages of scarring alopecia, the honeycomb pigmentation could be lost, making shiny atrophic areas more noticeable.
