This study found a significant overlap between gene expression signatures of alopecia areata and certain chronic inflammatory skin disorders, suggesting shared biological processes may drive their co-occurrence and providing a foundation for future research into distinct comorbid subtypes.

A specific hair protein variant increases the spread of breast cancer and is linked to worse survival rates.

This case report describes a 16-year-old girl with HAIR-AN syndrome requiring a multidisciplinary approach, including lifestyle changes and hormonal treatments, to manage symptoms and prevent systemic effects.

This study describes a case of vitamin D resistant rickets in a young girl due to end organ unresponsiveness, highlighting a possible new subtype of the disorder with distinct clinical features.

In this case report, pediatric HAIR-AN syndrome with severe acanthosis nigricans was significantly improved with metformin and liraglutide treatment, suggesting that early diagnosis and supportive treatment for symptoms like unexplained acanthosis nigricans and menstrual disorders can enhance quality of life.

This study found that, among 100 patients with alopecia areata, the most prevalent subtype was patchy alopecia areata, with characteristic trichoscopic features including black dots, yellow dots, and empty hair follicles.

This study concluded that terminal Schwann cells are essential for the maintenance and regeneration of mechanosensory lanceolate complexes at hair follicles in adult mice.

This review highlights cases of hair regrowth in certain patients with cicatricial alopecia, although the mechanism behind this regrowth remains unclear.

This study found that matrix progenitor cells in hair follicles move in a conveyor-belt-like fashion along the dermal papilla, changing their transcriptional states and lineage potential as they differentiate into inner hair follicle layers.

This review discusses treatment options for female pattern hair loss, emphasizing the importance of early intervention and the benefits of combined therapies, but reports no new clinical results.

In this in vitro study, minoxidil, diazoxide, and the novel compound NNC 55-0118 increased hair follicle growth, supporting deer follicles as a viable bioassay for ATP-sensitive potassium channel modulators.

This study found that alcohol dependence is associated with altered HPA axis functioning, with AD patients showing higher hair cortisol concentrations and reduced ACTH and cortisol levels, irrespective of childhood maltreatment history.

This case report discusses a 6-year-old girl with loose anagen hair syndrome, characterized by painlessly shedding hair, and notes no evidence of benefit from biotin supplementation.

This study found that the HairComb algorithm achieved high accuracy in quantifying percentage hair loss across various types of alopecia, suggesting its potential for standardized automated assessments.

This scoping review reports that preclinical studies suggest omega fatty acids may promote hair follicle growth, but clinical evidence is mixed, with no support for their standalone use in treating alopecia.

This study found that rat hair-follicle-associated pluripotent stem cells can be successfully differentiated into beating atrial and ventricular cardiomyocytes by using specific combinations of growth factors and inhibitors in culture, demonstrating their potential to form functional myocardial fibers similar to adult heart cells.

This study identified a gene transcript overexpressed in dermal papilla cells, showing strong similarity to a mouse gene associated with adipose tissue in bombesin receptor subtype-3-deficient mice.

Hair and nail conditions can stabilize or improve over time, and new treatments show promise.

This study found that alopecia areata often affects beard hair as frequently as scalp hair, leading the authors to propose a new scoring system and a subtype called alopecia subuniversalis for extensive hair involvement.

This study introduces "alopecia areata in a male or female pattern distribution" as a new clinical subtype of alopecia areata, observed in three adult cases, to enhance diagnostic precision and treatment personalization.

This review found that while follicular hair counts and ratios assist in diagnosing non-scarring alopecia, they should be used alongside specific morphological features for accurate diagnosis.

This study found that among users of glucagon-like peptide-1 receptor agonists, semaglutide and tirzepatide were associated with higher incidences of hair loss, particularly androgenetic alopecia and telogen effluvium, with rapid weight loss identified as a potential contributor to telogen effluvium.

This study found that among Chinese patients with alopecia areata, those with alopecia totalis/universalis had an earlier onset, longer duration, and more severe quality of life impact compared to those with patchy alopecia.

Baricitinib effectively promotes beard regrowth in most men with alopecia areata universalis.

This study found that nutritional deficiencies, particularly in amino acids and certain micronutrients, are common in individuals with hair loss across all types of alopecia.

This study provides scientific backing for the use of ECOHAIR® spray in patients with noncicatricial alopecia, showing improvements in hair volume, appearance, growth, and reduced hair loss over a 3-month period, with no local adverse effects reported.

This article discusses the causes and treatment options for lichen planopilaris, a scarring hair loss condition, but reports no new clinical findings.

This review discusses potential EMT-targeting drugs for treating lichen planopilaris and emphasizes the need for clinical trials, as current evidence is limited to individual cases or case series.

This study found that increased expression of type 2 TGF-β and type II receptor was observed in the bald vertex area of hair follicles from androgenetic alopecia patients, suggesting a role in catagen induction.

Targeting immune pathways like JAK/STAT may help treat frontal fibrosing alopecia.
