This study located a potential genetic link for androgenetic alopecia on chromosome 3q26, marking an early step in identifying new susceptibility genes for male pattern baldness.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.

In this study, significant upregulation of the genes SFRP2 and PTGDS was found in bald hair follicles of female pattern hair loss patients compared to non-bald follicles, suggesting these genes may be biomarkers and play a role in hair loss for this condition.

This study identified three novel genetic loci associated with PCOS and found similar genetic architecture across different diagnostic criteria, with evidence suggesting genetic links between PCOS and various metabolic and psychological traits.

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

This study identified changes in transcription factor gene expression across various signaling pathways during inner ear hair cell regeneration in birds, revealing patterns and potential new pathways for future investigation.

This study found that basement membrane components and structures in mouse hair follicles are highly specialized for specific inter-tissue interactions, with laminin α5 playing a crucial role in hair cycle regulation and anchoring.

In this study, a dual recombinase-mediated genetic system showed that cavity macrophages accumulate on the surface of visceral organs during lung and liver injury but do not penetrate or contribute to tissue repair.

This study demonstrated that lactate dehydrogenase activity is notably high in quiescent hair follicle stem cells within mouse skin using a specific enzymatic activity assay.

This study reveals that basement membrane composition and structure in mouse hair follicles are specialized for distinct inter-tissue interactions, with laminin α5 being essential for maintaining these interfaces.

This study suggests that down-regulation of vasculature-related genes in dermal papilla cells from balding scalps might contribute to the development of androgenetic alopecia.

Photodynamic therapy was effective in treating multiple scalp basal cell carcinomas with minimal side effects and good cosmetic results.

This case report in the Journal of Drugs in Dermatology discusses dissecting cellulitis of the scalp, emphasizing its disproportionate impact on Black males and the need for early diagnosis and effective management to mitigate scarring and quality of life issues.

This study found that faster algorithms for inferring ancestry in genomic data can better capture historical and functional insights into genome variation than traditional methods in large datasets like the UK Biobank.

In this study, researchers established five new immortalized human dermal papilla cell lines from a male with androgenetic alopecia, which may serve as valuable tools for hair research.

This study observed that both Factor XIIIa+ dermal dendrocytes and microvasculature size decreased with scalp aging and that alopecia changes resembled stress-induced premature senescence.

This study developed a deep learning model using the VGG architecture to predict hair disorders and provide tailored therapeutic suggestions, showing reliable recognition of conditions like dandruff, fungal infections, and alopecia by analyzing images of hair and scalp.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

In this study, human hair follicles showed varying expression of cholesterol transport proteins during the hair cycle, suggesting a potential role of cholesterol in hair growth and cycling.

This study found that male pattern hair loss worsened significantly after stopping finasteride, revealing a "rebound effect" where terminal hair transformed into miniaturized hair over 30 months off the drug.

This study suggests that finasteride's effect on promoting hair growth in men with androgenetic alopecia may be due to its inhibition of 5aR2 localized in hair follicles.

This study found that Wnt3a increased beta-catenin signaling and upregulated specific genes in cultured human dermal papilla cells, enhancing their response to PGE2 and potentially aiding hair growth.

This review reports that empirical evidence suggests an overlap between Long Covid, chronic fatigue syndrome, and fibromyalgia, highlighting the need for standardized definitions and rigorous methodologies in related research.

This letter to the editor discusses a previous clinical and histopathological analysis of four cases of severe diffuse non-scarring hair loss in systemic lupus erythematosus, reporting no new study results.

This study proposes a deep learning model using CNN with VGG16, VGG19, and MobileNetV2 architectures, achieving high accuracy in classifying scalp diseases from images, potentially facilitating diagnosis and treatment via mobile devices.

This study identified a genetic locus associated with coat type in domestic dogs, showing certain variants linked to single-coated breeds and suggesting potential regulatory roles.

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.

In this scoping review, researchers observed that while AI-assisted trichoscopy holds promise for standardized assessments of hair and scalp disorders, its clinical translation is limited by small proprietary datasets, inconsistent validation protocols, and a scarcity of real-world clinical studies.

Scalp tattooing may trigger hair regrowth in alopecia universalis.
