- Linear scarring (cicatricalis linearis; synonym: Leventhal-Luri linear scarring alopecia) is a familial disease of unknown etiology, characterized by linear foci of persistent hair loss with scar formation;
- Small focal (parvimaculata) - alopecia areata, characterized by small foci of alopecia; observed in the form of epidemic outbreaks in children;

- Newborns occipital (occipitalis neonatorum) - transient traumatic, develops in the occipital region in newborns with constant lying on the back;

- Premature (praematura; synonym: presenile) - of unclear etiology, develops in people of middle and young age, begins with the parietal or frontal region;
- X-ray (roentgenica) - occurs due to X-ray exposure; can be persistent (with a significant dose of radiation);
- Cicatrical (cicatricalis) - persistent, caused by cicatricial changes in the skin that have arisen due to injury or inflammation;
- Seborrheic (seborrhoica) - diffuse, occurs with seborrhea;
