Hair loss (baldness)

Scleroderma of the scalp.

Scleroderma rarely affects the scalp. Among its various forms in this localization, in descending order, there are linear scleroderma of the frontoparietal region, systemic scleroderma, widespread plaque and small focal scleroderma, or scleroatriphic lichen.

Lupus erythematosus of the scalp

Discoid lupus erythematosus (DLE) and disseminated lupus erythematosus of this localization can lead to focal atrophic alopecia of the scalp (pseudopelade condition).

The bullous form of red squamous lichen planus as causes of alopecia areata

Vesicular form of lichen planus (VFL) is a rare form of dermatosis (2-4% of all cases of this disease). Women over 50 are most often affected; blisters usually occur during a violent exacerbation of lichen planus, are accompanied by increased itching and are a stage of varying duration in the development of this dermatosis.

Atrophic form of red squamous lichen planus as a cause of alopecia areata

This rare clinical form of lichen planus accounts, according to various authors, for 2% to 10% of all forms of dermatosis. It manifests itself as flat, slightly elevated papules of a pale pinkish-blue color, up to the size of a lentil, which sometimes form ring-shaped lesions.

Pseudopelada, or atrophic focal alopecia areata.

The term pseudopelade, or atrophic focal alopecia, is used to describe small focal, slowly progressive cicatricial atrophy of the scalp with irreversible hair loss without pronounced perifollicular inflammation.

Circular alopecia

Circular alopecia (syn.: circular alopecia, focal alopecia, nesting baldness, pelada) is a disease characterized by the appearance of a round or oval patch of baldness with clear boundaries and outwardly unchanged skin.

Scarring alopecia

All skin lesions that lead to cicatricial changes also cause the death of hair follicles. The causes of cicatricial alopecia are very diverse.

Telogen and anagen hair loss

Anagen hair loss is excessive hair loss in the anagen phase, which is observed in patients with malignant neoplasms as a reaction to cytostatic and radiation therapy. Hair loss begins suddenly, 4-10 days after exposure, and can lead to total baldness.

Diffuse (symptomatic) baldness

Daily hair loss (up to 100) evenly over the entire surface of the scalp is a physiological process; the follicle that has lost its hair again enters the anagen phase and alopecia does not develop.

Normal hair loss (alopecia)

Common baldness is a physiological phenomenon in genetically predisposed individuals. Terminal hairs gradually transform into vellus hairs, i.e. a process of their "miniaturization" occurs, which can begin at any age after puberty.
