Tianeptine may help prevent hair loss by promoting hair growth and reducing cell death.

This study examined 16 sporadic trichoblastic tumors and found that although one showed malignant transformation, clinical follow-up revealed no residual or metastatic disease. RNA sequencing indicated a high tumor mutational burden and absence of a UV-related signature, helping to distinguish these tumors from similar growths.

This study found that in superficial angiomyxomas, S100A4-positive mesenchymal niches may induce non-neoplastic adnexal epithelial growth, and highlighted evidence of mesenchymal-to-epithelial transition in eccrine duct branching, especially in Carney's complex cases.

This study developed an in vitro artificial hair germ model using dermal papilla cells and skin keratinocytes to explore early stages of hair follicle regeneration.

This study found that in vitro, beard dermal papilla cells stimulated keratinocyte proliferation via androgen-dependent growth factors, while androgenetic alopecia cells released TGF-β1, inhibiting keratinocyte growth.

This study found that AIRE, a usually nuclear protein, is expressed in the cytoplasm of human epidermal and follicular keratinocytes and associates with the intermediate filament protein cytokeratin 17, potentially impacting ectodermal abnormalities in APECED syndrome.

This study found that recombinant keratinocyte growth factor (rKGF) stimulated hair growth and provided a protective effect against alopecia in murine models, suggesting its role in hair follicle development and regeneration.

Stopping sunscreen use on the forehead led to hair regrowth in a woman with frontal fibrosing alopecia.

Hair transplant and applying 5% minoxidil solution can effectively treat permanent hair loss, but it may change hair direction in some cases.

This study used single-cell and spatial transcriptomic profiling to identify specific molecular markers in human follicular dermal papilla cells, enhancing understanding of their role in hair follicle development.

In this study, researchers found that hair follicle stem cells in mice can generate both hair follicle and epidermis cells, highlighting their potential bipotency.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This article discusses the distribution of extracellular matrix molecules in human hair follicles and reports no new results.

This review explores the connection between psoriasis and hair loss, noting that both the disease and its treatments can contribute to alopecia, and reports no new clinical results.

This study showed that in C3H/HeJ mice, focal follicular inflammation starts before overt hair loss, with inflammation severity possibly reaching a threshold causing hair follicle dystrophy prior to visible hair loss.

This review discusses madarosis, its diverse causes, and suggests follicular unit transplantation as a useful treatment for scarring types, but reports no new clinical results.

This review summarizes the anatomy and physiology of the arrector pili muscle and discusses its potential role in hair loss disorders, reporting no new clinical results.

This review discusses the function and pathology of hair follicles and highlights the potential of using dogs as a model to study human hair and stem cell disorders, but presents no new experimental results.

This study found that adnexal acantholysis does not reliably distinguish pemphigus vulgaris from pemphigus foliaceus, but the level of acantholysis and degree of dyskeratosis serve as distinguishing features among acantholytic disorders.

This study found that hair regrowth in Pomeranians with hair cycle arrest treated with melatonin was not associated with a change in oestrogen receptor-α staining.

This study found that the presence of CD3(+) T-cells within empty follicular fibrous tracts is a reliable indicator for diagnosing diffuse alopecia areata instead of pattern hair loss.

This study reported that fibrosing alopecia in a pattern distribution can occur in patients of color, with clinical and histopathological features allowing for an accurate differential diagnosis.

This review discusses the role of hair follicle bacterial colonization in immune responses and the pathogenesis of alopecia but reports no new clinical results.

This article reviews central centrifugal cicatricial alopecia, including its various forms and potential multifactorial causes, but provides no new clinical findings.

This review discusses the structure, functions, and growth cycle of human hair, emphasizing its reduced growth and protective roles, and reports no new research findings.

This case study reports that a combination of PUVA therapy and oral methyl prednisolone initially improved symptoms of a woman's cutaneous T-cell lymphoma but required ongoing treatment due to recurrence.

This case report highlights the importance of trichoscopy in diagnosing fibrosing alopecia in pattern distribution, distinguishing it from female pattern hair loss, and guiding effective treatment.

This study reports a case where cyclosporine effectively treated a 51-year-old woman with idiopathic follicular mucinosis resistant to other therapies, suggesting its potential as an option for refractory cases.
