Types of alopecia:

Congenital (congenita) - persistent, develops from birth;
Congenital general (congenita totalis) - the absence of hair on the entire skin;
Congenital limited (congenita circumscripta; synonym: spotted atrichia) - absence of hair in limited areas of the skin;
Nest (areata; synonyms: circular, focal) - hair loss in one or more sharply limited rounded areas of the skin;
Nested marginal (areata marginalis; synonyms: Wilson's alopecia areata, ophiasis) - nested with localization in the peripheral areas of the scalp, more often in the occiput;
Alopecia areata (areata tonsurans) - an atypical form of alopecia areata, characterized by breaking of hair;
Diffuse (diffusa) - uniform hair thinning;
leprosy (leprosa) - symptomatic persistent alopecia, which has arisen due to trophic disorders in patients with leprosy;
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;
Neurotic (neurotica; synonym: Michelson's neurotic alopecia) - symptomatic alopecia that occurs in certain diseases of the nervous system;
Newborns occipital (occipitalis neonatorum) - transient traumatic, develops in the occipital region in newborns with constant lying on the back;
General (universalis; synonyms: generalized, universal) - the complete absence of hair on the entire skin;
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;
Symptomatic (symptomatica) - develops as a complication or symptom in any disease, skin damage or intoxication;
Syphilitic (syphilitica) - temporary, occurs in the secondary period of syphilis due to general intoxication or damage to the hair follicles;
Syphilitic diffuse (syphilitica diffusa) - a form of syphilitic alopecia with diffuse hair loss mainly in the temporal areas;
Syphilitic focal (syphilitica areolaris; synonym: syphilitic focal alopecia) is a form of syphilitic alopecia with many small rounded foci, located mainly in the occiput, temples, eyelashes and eyebrows;
Syphilitic mixed (syphilitica mixta) - a form of syphilitic alopecia with signs of small focal and diffuse syphilitic alopecia;
Senile (senilis; synonym: senile) - persistent, develops due to senile atrophy of hair follicles;
Thallium (tallica) - transient, develops due to the use of a thallium patch in the treatment of dermatomycosis;
Toxic (toxica) - symptomatic, develops due to intoxication;
Total (totalis; synonym: malignant alopecia) - a generalized form of alopecia areata, leading to complete hair loss on the entire head, and sometimes on other skin areas;
Traumatic (traumatica; synonym: Greenlandic) - occurs due to constant injury to individual areas of the hairline;
Triangular (triangularis frontoparietalis) - a form of congenital alopecia, looks like a one-sided triangular focus in the frontal-temporal region;
Epilinic (epilinica) - transient, develops when using an epilin patch in the treatment of dermatomycosis.
