The development of red nail lunulae has been extremely rarely described in alopecia areata. We observed 2 patients, a 30-year-old woman and a 61-year-old man, both suffering from severe alopecia areata, and having red lunulae. The colour changes, which developed a few weeks after the acute onset of hair loss, disappeared slowly, leaving horizontal fissures (Beau's lines).
