Pili annulati, or 'ringed hair,' is a disorder in which scalp hairs show alternating light and dark bands. It is often an incidental finding, and the hair usually does not show increased fragility (Green et al., 2004). See also pseudopili annulati (613241), a distinct entity. [from OMIM Pili annulati, also known as ringed hair, is a rare hair shaft abnormality that manifests as alternating light and dark banding and a speckled appearance of scalp hair. The lighter banding occurs due to clusters of abnormal air-filled cavities in the cortex of the hair shaft.

Pili annulati showed a wide dishomogeneity of the cuticular scales distributed along the hair shaft. Peripheral hair shafts were occasionally without scales (Fig. 5). Normal control hair showed a regular arrangement of the cuticular scales over the entire hair shaft (Fig. 6) pili annulati (PPA),15,16 bubble hair, pili torti, and monilethrix. The affected hair in PPA demonstrates a banded appearance similar to PA. Pseudopili annulati likely is a variant of normal with no reports of famil-ial cases or comorbid conditions.

Pili annulati refers to alternating bright and dark bands, with the bright areas corresponding to light scattered from clusters of air-filled cavities within the cortex.34 Pili annulati is also known as ringed hair because of the alternating dilations of the medulla that produce the banded appearance. 7 Pili annulati can be sporadic or inherited as an autosomal dominant trait and is merely of cosmetic concern as the associated hair is not fragile Trichoscopy of pili annulati demonstrates hair shafts with alternating white and dark bands. The white bands are subtle, cloudy, and shorter than the remaining, dark portion of the hair shaft. About 20-80 % of hairs are affected, and the bands tend to disappear distally Pseudopili annulati is a newly discovered anomaly of human hair which mimics clinical features of classical pili annulati but has an entirely different physical basis. Both are characterized by appearance of periodic bright bands along hair shafts viewed by reflected light. With pili annulati,.. pili annulati: [MIM*180600] a rare condition in which the hair shows alternate pigmented and bright segments, the latter due to air cavities within the cortex.

Pili Annulati is described as a disorder that results in ringed or banded hair, alternating bright and dark bands in the hair shaft.
