This article reviews the epidemiology, clinical evaluation, and pathogenesis of alopecia areata and highlights recent advancements, but it does not report new clinical findings.

This article discusses treatment options for androgenetic alopecia, noting that medical interventions like finasteride and minoxidil can halt and partially reverse hair loss in mild to moderate cases, especially when combined with surgery.

This study reports that the ScalpEye system accurately diagnosed dandruff, folliculitis, hair loss, and oily hair with a precision range of 97.41% to 99.09%.

This study found that Zizyphus jujuba essential oil enhanced hair growth in mice, with the 1% and 10% concentrations showing increased hair length compared to control.

This study concluded that combining vertical and transverse sections of scalp biopsy specimens improves diagnostic yield for certain hair disorders without increasing costs.

This review discusses trichoscopy as a noninvasive, effective technique for diagnosing various hair loss conditions and monitoring treatment, highlighting its potential to reduce scalp biopsy necessity.

This article reviews various types of primary cicatricial alopecias and emphasizes the importance of accurate diagnosis to improve management strategies, particularly detailing remaining lymphocytic forms and expanding on neutrophilic and mixed types.

This study found that MRL/MpJ mouse dorsal skin wounds heal with similar scar formation and collagen deposition as C57bl/6 and Balb/c mice.

This study demonstrated a method for large-scale preparation of self-sorted hair follicle germs in vitro, which successfully generated hair follicles when transplanted into the skin of nude mice.

Scarring alopecias are complex hair loss disorders that require early treatment to prevent permanent hair loss.

This review discusses three newly identified forms of epidermolysis bullosa related to mutations in DST-e, EXPH5, and ITGA3, offering insights into their genetic and clinical characteristics but reports no new clinical results.

This review provides a practical approach to diagnosing pseudopelade of Brocq and updates on treatment options but reports no new clinical results.

This article reviews various topics discussed at a workshop on hair disorders, focusing on hair biology, diagnosis, and challenges in therapy evaluation, without presenting new clinical findings.

This study showed that in C3H/HeJ mice, focal follicular inflammation starts before overt hair loss, with inflammation severity possibly reaching a threshold causing hair follicle dystrophy prior to visible hair loss.

This study found that TSC2-null fibroblast cells from TSC skin hamartomas can induce hair follicle formation and hamartomatous changes in keratinocytes, with active mTOR signaling observable in a mouse xenograft model.

This article discusses various types of primary cicatricial alopecias and reports no new clinical results; it emphasizes the importance of accurate diagnosis for effective management.

In this study, researchers identified a novel congenital skin disorder in Chesapeake Bay retrievers, linked to a plakophilin-1 deficiency due to a genetic mutation, marking the first known occurrence in an animal species.

This study found that systemic mycophenolate mofetil and topical clobetasol were equally effective at reducing lichen planopilaris activity over six months, but satisfaction differed between the treatments.

This study confirmed that the novel solid lipid microparticle formulation of adapalene demonstrated follicular penetration potential and targeted particle erosion in sebum in in vitro tests.

This study reports that horizontal sections of scalp biopsies improve the diagnosis of alopecia areata, especially when characteristic inflammatory infiltrates are missing.

A young woman's Cronkhite-Canada syndrome improved on its own after she gave birth.

This study identified trichoscopy as a key diagnostic tool for erosive pustular dermatosis of the scalp and suggested high-potency steroids or tacrolimus as effective first-line treatments.

This study found that scalp involvement in dermatomyositis consistently shows a nonscarring pattern with chronic telogen effluvium, featuring telangiectasia and mucin deposition as universal histologic markers.

Dermatoscopy helps diagnose hair and scalp disorders in people with Afro-textured hair, but more research is needed for better understanding and treatment.

This review discusses the classification and diagnosis of primary scalp alopecia, focusing on scarring and non-scarring types, and reports no new clinical results; it emphasizes simplified diagnostic pathways and tissue processing techniques.

This review discusses the potential of evaluating hair follicle characteristics as early indicators of vascular impairment and organ damage in pre-diabetic individuals, but reports no new clinical results.

This study demonstrated that molecular dynamics simulations of keratin could effectively model the mechanical properties of hair, aligning well with experimental data, especially when conducted in vacuum conditions.

This study demonstrated that adding human adipose-derived stem cells to hair follicle germ-like aggregates significantly improved hair shaft generation in transplanted nude mice, suggesting a promising strategy for hair regenerative medicine.

This study found that the Elastic Verhoeff–Van Gieson stain may help differentiate between follicular streamers and scars in cicatricial and noncicatricial alopecias by highlighting differences in the elastic fiber network on horizontal scalp biopsy sections.

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.
