This study analyzed trichoscopic features of discoid lupus erythematosus on the scalp in skin of color and found distinct patterns based on clinical morphology.

This study found that hypoxia-conditioned mesenchymal stem cell exosomes increased GM-CSF and decreased IL-1 expression in a dose-dependent manner in a murine model, suggesting potential for treating androgenetic alopecia.

This study observed that among 120 patients recovering from COVID-19, severe diffuse hair loss typically began less than two months post-infection, with the majority of patients experiencing a severe degree of hair loss and positive hair pull tests, often alongside vitamin D deficiency.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This article argues that androgen sensitivity could be a key factor in the severity of COVID-19, suggesting that trials with anti-androgen agents may be warranted.

This review discusses recent advances in trichoscopy for differentiating types of alopecia and presents a systematic approach for using its diagnostic findings, but reports no new clinical results.

In this study, after long-term observation of human scalp hair follicles over 16 years, the researchers found that a topical 5% minoxidil solution could stimulate hair regrowth after a period of dormancy, though with reduced growth rates and hair diameter.

Red dots on the upper chest may be an early sign of certain types of hair loss.

This study explored the use of flower-inspired analogies in dermatology, highlighting how these vivid descriptions aid in diagnosing skin conditions by drawing parallels between clinical features and floral patterns, effectively blending scientific observation with artistic imagery.

This study identified MPB susceptibility genes and potential drug candidates that may help uncover molecular mechanisms and address male-pattern baldness.

This study found that feather patterning is primarily self-organizing and dynamic, relying on both genetic and epigenetic controls, with implications for similar processes like fingerprints and pigmentation.

This study concluded that in female pattern hair loss patients, CGF and i-PRF treatments were more effective than PRP in increasing target area hair count, with i-PRF having the lowest adverse event rate.

This study characterizes alopecia in ARCI, highlighting its prevalence among patients with severe forms and revealing new associated trichoscopic features.

This study observed that while both minoxidil and botanically-derived 5-alpha reductase inhibitors significantly increased hair count and diameter in women with female pattern hair loss, minoxidil was more effective, especially for greater hair diameter increases, but had more troublesome side effects.

In this study, intradermal injections of extracellular vesicles over six months were reported to be safe and effective in improving hair growth among patients with pattern hair loss, with favorable response linked to specific patient factors and treatment volumes.

In this study, sorafenib's common adverse events, like a hand-foot syndrome and diarrhea, were observed in distinct temporal and tissue distribution patterns, revealing new relationships among effects.

This study suggests that yellow and white dot signs may be new dermoscopic indicators of advanced androgenetic alopecia in dark-skinned females, with certain trichoscopic features associated with darker skin types.

This study documented distinct expression patterns of stem cell markers LGR5 and LGR6 in various human skin tumors, highlighting differences in their potential roles and contributions to tumor development.

This study found that diffuse and pseudo-fringe sign patterns are common in Asian patients with frontal fibrosing alopecia, and that treatments combining antiandrogens or antimalarials with topical therapy are effective.

In this study, researchers found that topical treatment with adenosine improved hair growth and thickness by significantly increasing hair density and thickness after four months in vivo, with results comparable to minoxidil, potentially due to adenosine's anti-androgenic effects.

This study found that a catalytically active version of Vav2 significantly altered gene expression patterns in hair follicle stem cells in mice, with these changes varying over the animals' lifespans.

This study observed that in wild snowshoe hares, gene expression patterns during seasonal coat color change show a consistent lag between gene expression and visible coat color changes.

This study used developing mouse hair follicles to explore early epithelial bud formation, finding that the Rho GTPase regulator ARHGEF3 plays a crucial role in regulating cell fate and cadherin patterning, with knockouts showing disrupted morphology and increased straight hair follicle growth.

In this study, pediatric patients with overt polyautoimmunity frequently had systemic lupus erythematosus as an index disease, with clustering patterns revealing familial influence on autoimmune disease aggregation.

This systematic review evaluated 60 studies on trichoscopy in hair and scalp disorders, revealing gaps in accounting for variables like disease stage or hair texture, and underscoring a need for more comprehensive analyses to fully understand trichoscopic patterns.

In this research, experienced clinicians noted inconsistency in the reproducibility of the commonly used Hamilton-Ludwig scales for assessing pattern hair loss severity in photographic assessments, leading to the proposal of a new 5-point scale for staging female hair loss.

This study found that in wound-induced hair neogenesis, African spiny mice and laboratory mice exhibit different morphogenetic field formation patterns related to tissue stiffness, suggesting evolutionary developmental biology advantages.

In this study, researchers used a mouse model to identify an adipocyte-to-fibroblast conversion pathway that promotes mast-cell recruitment and dermal fibrosis in atopic dermatitis, suggesting a potential therapeutic approach to block this process and reduce inflammation and fibrosis.

In this study, researchers found that adults with alopecia areata exhibited trichoscopic features of empty follicular openings and tulip hair, while children showed more honeycomb pigment patterns and pohlpinkus constriction on their scalp lesions.

This study identified key dermoscopic markers such as yellow dots, black dots, broken hairs, and coudability hairs, which were associated with a poorer prognosis in alopecia areata patients.
