We present a 13-year-old girl who had alopecia areata and coincidentally was found to have pili annulati. Her mother also had pili annulati which had become more noticeable as her hair had become paler with age. [scienceopen.com]

Conclusions The present results suggest that the microcanaliculi of the hair surface, easily found with scanning electron microscopy, may be secondary not only to the cavities seen in the sections but also to the disorder of proteins that form this region [anaisdedermatologia.org.br]

Case Presentation A 12-year-old boy presented with a band of red hair over the interparietal region that was present since birth and had become more obvious over the years ( Figure 1A ). The rest of his scalp hair, eyebrows and eyelashes were brown. [dpcj.org]
