In this study, researchers found that supplementation with L-cystine, either alone or with a keratin hydrolysate, significantly improved hair density, hair and nail brightness, and nail growth in women experiencing acute telogen effluvium and brittle nail syndrome over three months.

This study demonstrated that a daily oral supplement of 1000 mg Kera-Diet® improved hair and nail conditions in women experiencing acute telogen effluvium and brittle nail syndrome over three months.

This review discusses the impact of COVID-19 on hormone therapy in gynecology, emphasizing the need for more high-quality evidence for individualized management, but it reports no new clinical results.

This study demonstrates that (9+2) topological patterns derived from fractal fiber sets exist, with nine total patterns and only two being independent or fundamental.

In this study, Leonuri Herba alkaloids significantly reduced prostate hyperplasia indicators and improved urinary parameters in hormone-induced model rats.

This study suggests that a specific region upstream of the TGF-β1 gene may play a key role in androgenetic alopecia by regulating gene expression in a cell-specific manner.

This review summarizes the role of G-protein-coupled receptors in wound healing and reports no new clinical results, highlighting their importance in signaling pathways and recent discoveries in their functions.

This study found that alopecia areata patients consider more than 20% scalp hair loss, chronic duration, and involvement of additional body hair as indicators of severe disease impacting quality of life.

This study found that dermal Shh signaling regulates specific dermal papilla signatures essential for maintaining hair follicle development, suggesting that the Shh-Noggin signaling loop is crucial for hair morphogenesis.

This study found that loss of the Pten gene in Lgr5+ hair follicle stem cells promoted squamous cell carcinoma formation through the Akt/β-catenin signaling pathway.

In this mouse study, hair growth defects associated with the Gk5 null allele were partially alleviated by simvastatin treatment, suggesting GK5 plays a key role in skin-specific cholesterol regulation.

This study found that despite carrying an activating Hras mutation, hair follicle stem cells integrate into normal skin without causing tumors, unlike similar mutations in the epidermis, suggesting unique tumor-suppressing mechanisms in hair follicles.

This study found that while autonomous Sema3A expression limited keratinocyte migration and delayed wound healing, non-autonomous application of recombinant Sema3A with EGF enhanced wound repair in mice.

This study identified FP-1 as a highly specific extracellular matrix protein in follicular papilla cells, which may play a role in hair growth regulation during specific hair cycle phases.

This study found that calcium microcapsules exhibited better biocompatibility and cell viability than barium microcapsules for scaffolding in artificial dermal papilla, suggesting potential for developing new hair follicle structures.

This study found that Ift20 is essential for hair follicle stem cell identity and hair regrowth, and it regulates keratinocyte migration during wound healing through focal adhesion integrin recycling, independently of ciliogenesis.

This research found that the microtubule catastrophe factor KIF18B plays a crucial role in promoting spindle orientation in keratinocytes, linking this process to cell fate decisions during hair follicle morphogenesis.

This study found that the K6/ODC transgenic mouse model is highly sensitive to identifying genotoxic carcinogens, showing 100% concordance with traditional rodent bioassays.

This study found that dimethylarsinic acid significantly accelerates skin tumor development in hair follicle-targeted K6/ODC transgenic mice.

In this study, treatment with recombinant DKK2 was shown to significantly stimulate hair progenitor cell growth and enhance hair shaft elongation in ex vivo human hair follicle cultures by activating the Wnt/ẞ-catenin signaling pathway, suggesting a potential role for DKK2 in promoting hair growth.

This study found that men with Kennedy disease have a significantly lower risk of androgenetic alopecia, likely due to androgen receptor gene alterations from the disease's polyglutamine expansion.

In this study, DataDerm revealed that from 2016 to 2022, a majority of patients diagnosed with keratinocyte carcinoma were male, predominantly white, and commonly between 56-75 years old, with most living in urban areas and having a history of non-melanoma skin cancer.

This review discusses recent research on the Dickkopf protein family's involvement in non-cancerous diseases and considers their potential as biomarkers and therapeutic targets without presenting new experimental results.

This study found elevated tissue levels of DKK-1 in patients with both androgenetic alopecia and alopecia areata compared to controls, suggesting DKK-1 as a potential therapeutic target for these conditions.

This study suggests that elevated DKK1 expression, influenced by promoter methylation, is a significant prognostic biomarker for patients with head and neck squamous cell carcinoma.

This case report describes a 54-year-old woman with familial dyskeratotic comedones who experienced slight improvement in her skin lesions after three months of treatment with topical retinoids and urea cream.

The researchers reported that DHT-inducible DKK-1 may play a significant role in DHT-driven balding by inhibiting hair follicle cell growth and promoting apoptosis in androgenetic alopecia.

TRIV-509 quickly improves skin barrier and cell health in atopic dermatitis.

This study found that overexpression of the enzyme ornithine decarboxylase in transgenic mice led to UVB-induced skin tumors, but this was prevented by the ODC inhibitor α-difluoromethylornithine.

This study found that adipose-derived stem cells with DKK1 knocked out using CRISPR/Cas9 promoted hair growth in an alopecia areata model more effectively than untreated stem cells, suggesting DKK1 is a potential therapeutic target for this condition.
