In this study, researchers mapped cysteine accessibility in wool keratins and KAPs, revealing that certain cysteines in keratin end domains and Types I and II rod domains are accessible and likely involved in forming disulfide bonds.

This review examines psychosomatic hair diseases, discussing their classification, implications, and the need for tailored psychosomatic therapy, without reporting new clinical results.

The paper suggests improving diagnosis and treatment of telogen effluvium but does not recommend a new classification system.

This study reported that over 70% of adults with primary cicatricial alopecia experienced impaired quality of life, primarily influenced by trichodynia and anxiety.

This report describes a case of acute telogen effluvium in a 38-year-old woman following recovery from COVID-19.

This article discusses the complexities in diagnosing hair shaft disorders and the potential insights hair microscopy can provide, without reporting new clinical findings.

This article presents a dissenting opinion, arguing that the case described by Dr. Molina et al. was diffuse alopecia areata, not acute alopecia areata as claimed, emphasizing the importance of distinct clinical differences.

This study found that hHbl gene expression is localized in the cortical cells of the human hair shaft and is notably high in pilomatricoma cells transitioning to hair shaft keratinocytes.

This study provides insight into the specific disulfide bond interactions between keratins and keratin associated proteins, suggesting non-random cysteine interactions crucial for stabilizing hair fiber structure.

This article discusses the potential of low-dose naltrexone as an adjuvant therapy for trichodynia in alopecias, noting its anti-inflammatory properties and need for further research.

Monilethrix has no effective treatment, but avoiding hair trauma helps manage it.

This study reports that a third of patients with SARS-CoV-2 infection developed acute telogen effluvium within three weeks, highlighting a notable pattern of early hair loss following COVID-19.

This study suggests that some keratin-associated proteins with antecedents found in non-haired animals may have roles beyond hair characteristics, possibly contributing to the evolution of hair follicles.

This comment discusses the use of 'follicular Swiss cheese' as a diagnostic feature for alopecia areata and does not report new clinical findings.

Stopping forehead irritation and using hydrocortisone helped a man's skin, Martinique has lower melanoma rates, a man had an allergy to a specific antifungal, another had unexplained cysts, certain drugs can cause skin reactions without always being interrelated, a link between Fanconi anemia and a skin condition was suggested, high levels of a certain protein may play a role in a type of psoriasis, and there's a need to study the connection between scalp pain and hair loss.

This review discusses the characteristics, triggers, and individualized treatment options for sensitive scalp but presents no new research findings.

This study reported that among patients aged 19 to 60 who experienced hair loss after COVID-19, a treatment involving a complex drug and peptide lotion led to hair improvement in 92% of cases, with good tolerability and no reported side effects.

This study reported that sensitive scalp symptoms, including trichodynia, are frequently found in hair loss patients, particularly among those with telogen effluvium and alopecia areata.

This case report describes a patient with systemic lupus erythematosus who developed both alopecia areata and lichen planopilaris despite immunosuppressive treatment, suggesting a shared immunopathogenesis between these disorders.

This study found that patients with telogen effluvium who delayed hair washing or collected shed hair were more likely to have higher clinical severity and increased disease-related economic burdens, suggesting these behaviors can aid clinical assessments.

This study observed that 675-nm diode laser therapy may serve as a safe and possibly effective adjuvant treatment for telogen effluvium, showing improvements in hair pull test results, pruritus, and trichodynia among patients. However, controlled studies are needed to confirm its efficacy.

This study reported that diffuse lichen planopilaris significantly impairs quality of life in Moroccan patients, with trichodynia and hair quality changes most affecting daily functioning and leisure activities.

This article discusses the characteristics, diagnosis, and clinical presentation of different variants of lichen planopilaris on the scalp, with emphasis on cicatricial alopecia and the importance of clinical and trichoscopic monitoring; it presents no new clinical results.

This study outlines trichodynia, a painful scalp condition often linked with various types of alopecia and psychiatric disorders, noting the absence of specific treatments and highlighting the need for further research on therapeutic options.

This retrospective study observed that telogen effluvium, a type of diffuse hair loss, frequently occurs in females aged 18–30 following SARS-CoV-2 infection, often accompanied by nutritional deficiencies, suggesting an association between COVID-19 and micronutrient deficiency, with acute cases being most common but chronic cases possible.

In this study, the researchers found that their conductive bio-harvesting tonic enhanced hair follicle proliferation and delayed regression with electric stimulation and the antifungal agent 6-pentyl-α-pyrone in both mice and human hair follicle tests.

The authors concluded that "burning scalp" syndrome lacks general treatment recommendations, but therapeutic cosmetics showing antipruritic and anti-inflammatory effects may offer promise for long-term management and prevention.

In this study, telogen effluvium, a common form of hair loss linked to changes in the hair cycle, is examined with a focus on diagnostic methods and effective treatment options, noting that 34.2% of patients experience trichodynia.

This report describes a case study of a 23-year-old female exhibiting multiple trichodiscomas, a type of benign tumor of the hair follicular discs common in familial cases and potentially linked to Birt-Hogg-Dube syndrome, though genetic testing was not performed due to financial constraints.

This study found that in female patients with COVID-19-related hair loss, diffuse hair loss and antinuclear antibody positivity might be linked to high antibody levels triggered by the infection.
