Hair changes may indicate disease activity in pemphigus patients.

In this retrospective study, researchers from the University of Bologna observed that trichoscopy can aid in diagnosing allergic scalp contact dermatitis, with key findings including common trichoscopic patterns of erythema, white scales, arborizing vessels, and simple red loops in 12 patients diagnosed with the condition.

This review examines the trichoscopic characteristics of scalp DLE and LPP, correlating these findings with histopathological data, but provides no new clinical results.

This study found that individuals with patterned hair loss, both male and female, showed a slower linear hair growth rate compared to controls with hair of equal thickness.

This study reviews the genetic mechanisms behind cat coat patterns, revealing that specific loci determine tabby variations and suggesting these patterns could unravel broader developmental and evolutionary biology insights.

In this hospital-based cross-sectional study, researchers observed that trichoscopy effectively differentiates between severe and mild male pattern hair loss by identifying specific features such as yellow and white dots, vellus hair, and hair shaft diversity.

This report describes a case of a 4-year-old boy diagnosed with linear alopecia areata, characterized by patchy hair loss and associated with unique hyperpigmented skin lesions.

This study developed a grooved microneedle platform enabling precise transdermal delivery of triamcinolone acetonide for alopecia areata, achieving accurate dosing by controlling groove position and drug concentration.

This article reviews the use of trichoscopy for diagnosing and monitoring various scalp conditions, but it presents no new experimental findings; the authors emphasize its precision in noninvasive evaluation.

This report documented a successful and sustained hair restoration surgery using follicular unit transplantation for temporal triangular alopecia, lasting over six years.

The study observed that patterned fibrosing alopecia, a type of scarring hair loss, appears in some patients after hair transplants, facelifts, and other surgical interventions, sharing features with lichen planopilaris and androgenetic alopecia.

In this hospital-based observational study involving 30 participants, researchers found no statistically significant difference in the force needed to pluck anagen versus telogen hair in the frontal and occipital scalp regions of women with female pattern hair loss.

This study suggests that a prototype device may accurately measure hair quantity, diameter, and density in balding patients, potentially aiding in diagnostic assessments, though formal clinical studies are needed to confirm its effectiveness.

In this study, researchers found that nearly half of Korean women with female pattern hair loss showed temporal scalp involvement, with a decrease in temporal hair density compared to occipital areas.

Trichoscopy is effective in diagnosing trichotillomania by showing specific hair patterns.

This study developed finite element models to examine skin's biomechanical properties, finding that structural heterogeneities like Rete ridges and hair follicles create distinct stress and strain patterns that may influence mechanosensation and skin integrity.

This study reports five cases of congenital triangular alopecia featuring a central island of short terminal hair, with the cause remaining unknown.

This study found that most hair shaft abnormalities can be accurately diagnosed using a handheld dermoscope in a clinical setting.

This study observed that temporal triangular alopecia in infants presents with distinct clinical and dermatoscopic features, indicating the usefulness of dermatoscopy for diagnosis and differential diagnosis.

This study observed that fibrosing alopecia in a pattern distribution shows varied histological features and may resemble lichen planopilaris with initial diffuse distribution, potentially leading to scarring alopecia.

In this case study, a 20-year-old man experienced progressive hair loss starting as a localized patch on the vertex of his scalp, eventually spreading in a curvilinear pattern to the sides and back.

This report details two cases of alopecia areata with unusual annular and circinate patterns, highlighting atypical morphology of the condition.

This study found that a combined pattern of repigmentation was most commonly observed in vitiligo, with a new 'medium spotted' pattern proposed for areas with few hair follicles.

Tufted folliculitis is common in patients with folliculitis decalvans.

In this study, researchers observed that trichoscopy could reliably identify features such as anisotrichosis and signs associated with inflammation and fibrosis in female pattern hair loss, which may aid in assessing disease severity and guiding treatment decisions.

Trichoscopy helps tell different hair loss types apart using specific scalp and hair patterns.

Most older adults experience pattern hair loss due to shrinking hair follicles, with men and women showing different balding patterns.
