Trichotillomania is a form of traction alopecia resulting from repetitive and compulsive hair pulling and plucking. Trichotillomania and patchy alopecia areata may have similar clinical and dermoscopic features in some cases. On trichoscopic examination, the presence of black dots, coiled or hook hair, shafts of varying lengths with fraying or split ends (trichoptilosis), and an absence of exclamation mark hairs and yellow dots are suggestive of trichotillomania.

Frontal Fibrosing Alopecia (FFA) is a primary lymphocytic cicatricial alopecia predominantly affecting postmenopausal Caucasian women. It is characterized by a progressive frontotemporal hairline recession that presents as a scarring hairless band and is often accompanied by eyebrow and body hair loss. Although initially described in postmenopausal women, FFA has been observed in a broader demographic, including premenopausal women and occasionally men.

Background: Afro-textured hair exhibits distinct physicochemical properties with possible variations in measurable hair parameters. Standardized documentation of trichoscopic norms of afro-textured hair in indigenous Africans is notably lacking.
Methods: A cross-sectional study involving 122 South Africans of both genders of African ancestry (mean age 20.

Introduction: Ultraviolet-induced fluorescence dermoscopy (UVFD) is increasingly utilized in dermatooncology and general dermatology. The objective of the study was to characterize the ultraviolet-induced fluorescence trichoscopy (UVFT) findings in a wide range of hair and scalp conditions.
Methods: Consecutive patients with non-scarring alopecias (alopecia areata, AA, n = 40; androgenetic alopecia, AGA, n = 40), scarring alopecias (frontal fibrosing alopecia, FFA, n = 20; lichen planopilaris, LPP, n = 20; folliculitis decalvans, FD, n = 14; discoid lupus erythematosus, DLE, n = 23), and inflammatory scalp conditions (psoriasis, n = 30; seborrheic dermatitis, n = 14) were included.

Pili trianguli et canaliculi syndrome is a rare hair shaft disorder characterized by frizzy hair that cannot be smoothed flat. Affected hair shafts are triangular or kidney-shaped with longitudinal grooving. Diagnosis typically requires electron microscopy, which may be cost-prohibitive, or alternatively, the distinctive features of hair shafts can be identified through histological examination of cross sections, that is time-consuming.

Background: Frontal fibrosing alopecia (FFA) is a scarring hair loss condition primarily affecting the frontotemporal hairline and often leading to partial or complete loss of eyebrows in a significant number of cases. It is characterized by slow progression and typically shows poor response to available treatments. Diagnosis relies on clinical, trichoscopic, and histopathological assessments, with specific criteria proposed by Vañó-Galván et al.
