This study observed that bacterial communities on scalp hair collected through non-invasive swabbing showed similar diversity and composition to those obtained by cutting or removing hair, suggesting that swabbing is an effective method for microbiome analysis on hair.

This study suggests that chest, arm, leg, and beard hair samples may be viable alternatives to scalp hair for monitoring long-term alcohol intake, although body hair is more typically collected from men.

This study found that a laboratory model using nude mice can produce human hair follicles with amino acid compositions resembling both normal and trichothiodystrophy-affected human scalp hair over extended periods.

This study found no significant proteomic differences in hair samples across racial or geometric groups in a culturally diverse South African cohort, highlighting the limited value of racial classification in precision medicine.

This study presents the Italian adaptation of the ECR-M16 to assess attachment dimensions in cancer outpatients and notes that its factor structure is partly similar to the original.

In this report, six elderly women with a novel pustular dermatosis of the scalp experienced chronic lesions unresponsive to antibiotics but were effectively managed with potent topical steroids.

In this study, the researchers found that measuring tacrolimus levels in scalp hair could be a reliable method for monitoring drug exposure in kidney transplant recipients, offering an alternative to frequent blood tests by utilizing self-collected hair samples.

SACUMAN, a rare condition causing hair loss without clear signs, is often misdiagnosed and needs scalp biopsies for accurate detection.

This study reports that Broussonetia papyrifera extract significantly increased hair count over 12 weeks in a small clinical trial and promoted dermal papilla cell proliferation in vitro by regulating WNT-β-catenin and STAT6 pathways.

In this cross-sectional study conducted at Farhat Hached Hospital in Tunisia, more than half of the 60 alopecia areata patients surveyed experienced depression, particularly younger individuals and those with severe or specific forms of the condition, underscoring the need for psychological support.

This study found a decreased number of follicular melanocytes in patients with alopecia areata, though it remains unclear if this decrease is due to autoimmune attack or rapid hair cycling.

This study found that the retinoid receptor and PPAR pathway are involved in hair follicle miniaturization in androgenetic alopecia, alongside androgen receptors.

This study observed that multinucleate giant cells were present in 31% of biopsy specimens from patients with male pattern alopecia but not in other alopecia types, suggesting a potential histologic marker for androgenetic alopecia.

This paper provides an auditable companion package for their exploratory re-analysis of miRNA dysregulation and target enrichment in female pattern hair loss cases, focusing on candidate-level results from a public dataset comparison between affected individuals and healthy controls.

In this study, researchers conducted an exploratory re-analysis of miRNA dysregulation and aging-related target enrichment in female pattern hair loss using data from public GEO dataset GSE106780. The findings are preliminary and should be interpreted as candidate-level results due to the small sample size.

This study identified distinct immune differences in patients with alopecia areata, particularly those with atopic backgrounds, and highlighted the OX40 axis as a potential therapeutic target for the condition.

In this study, researchers found that targeting a tacrolimus trough level of 4–7 ng/mL after liver transplantation resulted in comparable graft and patient survival rates to higher levels, while improving liver and kidney function markers.

This study suggests that collecting hair samples from all scalp regions may be a viable alternative for measuring cortisol in individuals with Afro-textured or extremely short hair, aligning results with traditional methods.

This review outlines a systematic method for diagnosing hair loss and presents no new findings; the authors emphasize the importance of biopsy in cicatricial alopecia cases.

This study found that direct immunofluorescence of hair is a simple and non-invasive alternative for monitoring pemphigus vulgaris, matching skin biopsy results in the cases observed.

In this study, transverse sectioning of scalp biopsy samples showed higher diagnostic accuracy than vertical sectioning for noncicatricial alopecia, although both techniques are important for accurate diagnosis.

This study found that women with alopecia have significantly lower tensile strength in both dry and wet hair samples compared to controls, indicating increased hair breakability.

In this single-cell transcriptomic study, researchers analyzed AA scalp samples and found distinct immune and nonimmune cell activation patterns, with elevated TH1/TH2 and JAK/STAT markers potentially contributing to hair follicle immune privilege disruption and disease severity.

This study discusses using SEM/EDX for elemental analysis of hair samples in forensic science but notes challenges in detecting certain trace elements from raw hair.

This paper discusses methods for distinguishing viable microbial communities in hair follicle dysbiosis studies and reports no new clinical results, suggesting potential improvements in sample analysis.

This study highlights the complexity of diagnosing scalp fungal infections, emphasizing how clinical evaluation, trichoscopy, and cultural samples are essential in distinguishing tinea capitis from similar conditions like piedra, seborrheic dermatitis, and psoriasis, due to overlapping symptoms like scaling and hair changes.

This study found that androgenetic alopecia may involve a defect in the conversion of hair follicle stem cells to progenitor cells, as demonstrated by a reduced presence of progenitor cells in bald scalp samples.

This study explored the fungal diversity on human scalps, identifying 15 genera and 24 species from 18 scalp samples of girls, with yeast-like structures found in 33.3% of cases. Additionally, zinc oxide nanoparticles, synthesized using ginger extract, showed significant antifungal activity against specific species.

This study concluded that their modified immunohistochemical staining protocol can determine the ABO blood group of both medullated and non-medullated scalp hair, potentially aiding in hair sample screening before DNA analysis.

This study found that glycated proteins in untreated scalp hair may serve as a non-invasive marker for blood glucose control, but its applicability is limited by factors like cosmetic treatments and sample collection challenges.
