This study identified a novel locus for hereditary hypotrichosis simplex on chromosome 13q12.12~12.3 in a four-generation Chinese family.

This case report describes a 12-year-old girl diagnosed with monilethrix, characterized by fragile, beaded hair shafts, with no effective treatment currently available.

This perspective discusses Villani et al.'s findings on the role of the IGF regulatory protein Igfbp2 in basal cell carcinogenesis and highlights potential therapeutic and preventive targets, while raising questions about the cell of origin.

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.

This review discusses the role of heparan sulfate proteoglycans in regulating stem cell fate and highlights their potential as targets for addressing hair loss, without reporting new clinical results.

This article reviews the roles of several signaling pathways and molecules, including FGFs, Hh, Notch, TGF, and Wnt, in the development of teeth and hair follicles, but reports no new findings.

This study found that Puerariae Radix ethanol extracts increased the proliferation of human hair dermal papilla cells via ERK and Akt phosphorylation, suggesting potential benefits for alopecia treatment.

This study identified a novel mutation, R430Q in the KRT86 gene, in a Han family with monilethrix, which may contribute to the disease's pathogenic mechanism.

In this study, a novel heterozygous transition mutation in the KRT86 gene was identified, which may be pathogenic for monilethrix in a Chinese family.

This study reported that Hedgehog signaling in papillary fibroblasts is crucial for hair follicle regeneration during wound healing, emphasizing its potential for developing regenerative therapies in scarring wounds.

This study found that a combination of oral compounds improved metabolic activity, cell viability, and proliferation in hair follicular keratinocytes, with L-cystine playing a key role in protection against oxidative stress.

The researchers concluded that baicalin may promote hair growth and follicle proliferation by activating the AKT pathway, suggesting its potential as a treatment for alopecia.

This study found that both bFGF and herbal extracts significantly induced proliferation in human hair follicle mesenchymal stem cells, suggesting their potential for promoting hair growth.

This study identified the c.1204G to A (p.E402K) mutation in the hHB6 gene as a cause of monilethrix in a Chinese family, highlighting the gene's role in the condition.

This study found that pilomatricomas exhibit co-expression of hair keratin hHa5 and HOXC13 in lower transitional cells, but lack LEF1 and β-catenin co-expression necessary for canonical Wnt signaling pathway-controlled cortical differentiation.

This study found that topical patidegib gel significantly shrank basal cell carcinomas in Gorlin syndrome patients without causing the systemic side effects common with oral hedgehog inhibitors.

This review examines the origins and mechanisms of tumor initiation in common skin cancers, but does not present new experimental findings; it emphasizes the need for further research on cancer stem cells.

Er:YAG laser therapy effectively treats Hailey-Hailey disease, leading to long-term remission and improved quality of life.

This study found that Ashwagandha-derived nanovesicles increased cell proliferation, angiogenesis, and growth factor expression in vitro, suggesting they may have potential as a plant-based alternative or complement to current therapies for hair and skin conditions.

This case report presents a 14-year-old girl with both type I diabetes and monilethrix, detailing her symptoms and treatment with topical minoxidil, while exploring a possible genetic link between the conditions.

This case report describes a 6-year-old girl diagnosed with monilethrix, experiencing hair fragility and loss after a fever, and showing improvement in hair density following treatment, despite persistent symptoms.

In this review, the authors explore strategies for inducing scarless skin regeneration by modulating dermal signaling or specific fibroblast subsets to promote the formation of new hair follicles in wounds, particularly focusing on mimicking neonatal skin's regenerative capabilities.

In this study, researchers found that both Wnt/β-catenin and Hedgehog signaling pathways must be activated in wound fibroblasts to promote hair follicle neogenesis in mice, suggesting these pathways are crucial for regenerative healing strategies.

This study found that inhibiting the HEDGEHOG-GLI1 pathway could reduce keloid size and gene expression, suggesting it as a potential therapeutic target for keloid pathogenesis.

This study observed that the Hedgehog-GLI1 signaling pathway is upregulated in keloid patient–derived stem cells, and inhibiting this pathway reduced keloid characteristics in both mice and ex vivo tissue cultures, suggesting potential therapeutic targets for keloid treatment.

In this study, activation of Hedgehog signaling in both epithelial and stromal cells induced new hair follicles in adult mouse skin, but also resulted in the formation of tumors.

This study found that activating Hedgehog signaling in both epithelial and stromal cells can induce new hair follicles in adult mice, but this also leads to tumor formation.

Targeted therapy for skin cancer is complex due to the role of the hedgehog pathway in both cancer and hair growth.

This study revealed that Patched receptors establish a Hedgehog signaling gradient in developing hair follicles, which may influence their formation and potentially offer a diagnostic tool for distinguishing Hedgehog-driven tumors.

This study found that ferulic acid effectively stabilized vitamins C and E in a topical solution, doubling skin photoprotection against solar-simulated irradiation, which may help in preventing photoaging and skin cancer.
