This article reviews the rationale and science behind forensic hair examinations and discusses the role of microscopic and DNA techniques in differentiating hair sources but reports no new findings.

Hair analysis can offer clues about a person, but individual differences limit making precise identifications.

This study found that higher scores of hair loss on the Hamilton-Norwood scale correlated with increased hair gain in the conchal bowl in men, suggesting potential age-related adaptations beyond cosmetic concerns.

In this study, patients with keratosis pilaris exhibited significant quality of life impairment, with histopathology and dermoscopy revealing consistent skin and hair changes.

This study observed that the degradation product PTeCA significantly increased in hair treated with oxidative cosmetics, suggesting it could be a reliable marker for detecting such treatments, with a proposed PTCA cut-off value using PTeCA as the gold standard.

This review reports that pharmacogenomic variations in the SULT1A1 enzyme significantly influence the response to minoxidil treatment for alopecia, suggesting personalized therapeutic strategies could improve efficacy while emerging pharmaceutical technologies aim to optimize oral minoxidil's absorption and minimize side effects.

At a workshop highlighted during the 2025 ESPCR meeting, researchers discussed the challenges and variability in culturing skin-related cells, identifying key factors such as media composition and species differences that affect experimental reproducibility, and emphasized the importance of transparent practices to advance pigment cell research.

This study found that upcycled postbiotic cell-free supernatants from Limosilactobacillus fermentum MG901 and MG4237 protected human dermal papilla cells from oxidative stress, enhancing wound-healing capacity and mitochondrial function, suggesting potential as a sustainable cosmetic ingredient for hair loss alleviation.

This study found that using human hair follicle dermal papilla cells, 53BP1 focus counting can estimate radiation doses from 50 mGy after 5 hours, and focus size analysis refines dose estimation for doses ≥ 500 mGy up to 96 hours.

This source discusses a Phase 2 trial by Hu et al. that evaluated the efficacy of topical GT20029 compared to a placebo, though the abstract does not provide specific results.

The study's findings on VLDL as a biomarker for hair loss are unreliable.

This study found that perceptions of scalp micropigmentation and awareness of its side effects vary significantly by gender and age, influencing attitudes and intentions toward the procedure.

This source details the process necessary to substantiate "clinically proven" claims for products, emphasizing the importance of rigorous clinical trials, regulatory compliance, and emerging technologies in ensuring safety, efficacy, and credibility across diverse populations and settings.

A new tool helps better assess and treat hair loss in Chinese men.

RF-mesotherapy with bicalutamide may be a promising new treatment for hair loss.

The article's findings are unreliable and have been retracted.

In this study, corrected data confirmed that AHFS seed microspheres exhibit good biocompatibility with fibroblasts, validating the initial results.

This review systematically analyzed 22 clinical trials on hair care, finding that while most studies employed appropriate statistical methods, significant inconsistencies in reporting test assumptions and effect sizes may hinder reproducibility, highlighting a need for better standardization and transparency in these research practices.

This abstract introduces androgenic alopecia as the most common form of non-cicatricial alopecia, which predominantly affects men but also has a significant occurrence in women; however, specific research results or conclusions about treatments or mechanisms are not reported in the summary.

The study's findings on omega-6 and hair loss are unreliable.

This study identified specific gut bacterial pathways that may serve as potential therapeutic targets for managing androgenetic alopecia in obese individuals.

This study focused on developing and validating standardized methods to reliably assess hair growth and scalp health in androgenetic alopecia, finding significant differences in hair parameters such as vellus and terminal hair counts, density, and thickness between affected and standardized areas.

This study found that ultraviolet-induced fluorescence dermoscopy enhanced the identification of follicular openings in alopecia areata, potentially aiding in the assessment of disease severity and treatment strategies.

The researchers reported that a combined oral minoxidil-finasteride regimen significantly improved hair density in men with androgenetic alopecia over 12 months, although further confirmation in different trials is suggested.

This source highlights the preference for herbal-based products over chemical treatments for managing alopecia and explores their potential in hair treatment and regrowth.

This review examines the role and significance of next-generation sequencing technologies in forensic identification and other forensic applications, but reports no new findings.

This review discusses the genetic causes and pathogenesis of Olmsted syndrome, emphasizing the potential for a genotype-phenotype correlation due to TRPV3 mutations, and explores avenues for individualized treatment developments for this condition.

In this study, researchers developed and tested an Italian version of the Skindex-16AA to assess Health-Related Quality of Life in patients with moderate-to-severe Alopecia Areata, emphasizing the importance of patient perception in evaluating their mental health and quality of life.

The article on the stomach-protecting effects of Cibotium barometz hair was retracted due to unreliable data.

In this study, a machine-learning model was evaluated for its ability to categorize various hair conditions, achieving high accuracy and balance between precision and recall, with an overall accuracy of 97% in detecting hair problems.
