This review argues that the immunocompetence hypothesis, linking masculine facial features to attractiveness through health benefits, lacks sufficient evidence and sidesteps alternative explanations.

This report describes a 9-year-old girl with a scalp kerion treated successfully with terbinafine and ketoconazole shampoo, leading to hair regrowth after two months.

This study reported a case where a 46-year-old woman developed alopecia without itching or pain on her scalp due to a cutaneous infection from *Mycobacterium abscessus*, which was resolved after three months of antibacterial treatment, resulting in new hair growth.

This case report highlights two instances of suspected human herpesvirus 6 reactivation in patients with existing psychiatric disorders, underscoring the need for further research into the relationship between viral reactivation and psychiatric conditions.

This case report describes the presentation of a 32-year-old Iranian immunocompetent female diagnosed with Merkel Cell Carcinoma, highlighting the importance of early diagnosis and management to mitigate complications.

This study found that in healthy men, higher levels of free testosterone were associated with a stronger immune response to the influenza vaccine, suggesting androgens may function as immunomodulators rather than strict immunosuppressants.

The study introduced an advanced skin model, ImmuSkin-MT, which effectively distinguished between different strengths of skin sensitizers by mimicking the interaction of immune cells in skin tissue.

In this case report, a patient developed facial zona zoster as an unexpected complication following cryotherapy, adding to the list of known adverse effects such as dyspigmentation, scar formation, and hair loss.

This case study reports a rare instance of a subcutaneous abscess caused by Candida albicans infection in a 42-year-old Japanese woman following laparoscopic cholecystectomy.

This case report highlights a rare instance of syphilitic alopecia and ocular syphilis in an immunocompetent, HIV-negative woman, showing that syphilis-directed treatment led to symptom reversal, emphasizing the need to consider syphilis in the differential diagnosis for atypical alopecia.

This article highlights that tinea capitis, a fungal scalp infection primarily seen in children, is often misdiagnosed in adults, especially postmenopausal women and immunocompromised individuals, leading to unnecessary treatments and potential permanent hair loss if not correctly identified and treated.

This study found that restoring the skin microbiome significantly improved hair growth and skin condition in androgenic alopecia model mice by modulating the immune-inflammatory balance, highlighting the potential of bacterial-based therapies for hair loss.

This case report describes a 29-year-old man who developed scalp abscesses due to Mycobacterium abscessus infection after receiving scalp injections for hair loss, successfully treated with antibiotics.

This review covers the epidemiology, clinical features, and treatment of four common skin infections in children, reporting no new experimental findings.

This study found that microencapsulated dermal papilla cells implanted into mice ears led to the successful regeneration of hair follicles, with APA microencapsulations of 400µm diameter allowing effective nutrient exchange.

This case report highlights an atypical presentation of favus in an immunocompetent adult, where a psoriasiform plaque over the 'bindi' area was successfully treated with systemic itraconazole, achieving complete resolution without relapse. Simple stains proved essential for diagnosis in this resource-limited setting.

In this case study, a 45-year-old immunocompetent woman with tinea capitis exhibited an unusual presentation of the infection with a scaly plaque and hair loss, which responded well to treatment with itraconazole.

In this study, demodicoses were found to be relatively common among immunocompetent patients, with a notable overlap with papulopustular rosacea.

The study reported that Demodex musculi infestation was notably higher in immunodeficient mice, while infested immunocompetent mice, particularly the BALB/c strain, showed increased IgE levels and developed alopecia over time.

This study demonstrated that gene-corrected 3D skin constructs from RDEB patient-derived iPSCs, grafted onto immunocompetent mice, showed normal collagen VII expression after two months.

This literature review highlights the changing epidemiology of tinea capitis due to global migration and underscores the importance of early recognition and treatment of atypical variants in immunocompetent children to minimize prolonged systemic antifungal therapy and prevent adverse events, especially regarding liver health.

This study observed that pantethine, a vitamin B5 precursor, attenuates tumor growth in immunocompetent mice by enhancing antitumor immunity, but its effect is limited by immune cell exhaustion over time.

This study observed that M. domestica larva-derived chitosan and gut extracts enhanced wound healing and collagen deposition in both immunocompetent and immunosuppressed mice, indicating potential benefits for combined therapy.

In this case study, a 70-year-old woman with generalized favus caused by Trichophyton schoenleinii achieved a clinical and mycological cure after a one-month terbinafine treatment.

This study found that ingenol mebutate treatment led to gene expression changes in actinic keratoses, with complete lesion clearance in 40% of patients and identified genetic markers potentially predicting treatment response.

This study observed that in varicella, the varicella-zoster virus spreads to dermal endothelial cells before reaching keratinocytes, whereas in herpes zoster, it first involves cutaneous nerves and pilosebaceous units.

This study found that HPV-150 and HPV-151 are rare genotypes with a preference for skin tissue, detected in some cases of skin lesions with generally low viral loads.

This study found that hair follicles may provide a safe space for tumor cells in mice, suggesting a potential target for cancer prevention during the dormant phase of tumor development.

This study suggests that itraconazole may significantly improve therapy for aspergillosis, with 12 out of 15 evaluable patients responding to the treatment.

This study found that serum-free expanded hair follicle mesenchymal stem cells (hfMSCs), derived from hair plucking, significantly improved cartilage repair in a murine model despite minimal engraftment, suggesting their effectiveness through a paracrine mechanism.
