Our plain-language summary of this paper — not a Tressless recommendation.
The document described three patients with alopecia areata who exhibited a spotty absence of the whiteness of the lunulae in their nails. This phenomenon was attributed to defects in the tongue of matrical epithelium beneath the nail plate, which is responsible for the lunula. The study drew an analogy with Wickham's striae, suggesting a similar underlying mechanism.
