This review discusses mesenchymal–epithelial interactions in hair follicle development and cycling, highlighting recent insights without reporting new experimental results.

This study found that Hoxc gene expression can reprogram mesenchymal dermal papilla cells, enhance epithelial stem cell regenerative potential, and promote region-specific hair follicle regeneration through Wnt signaling.

This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.

In this study, tofacitinib treatment in a male patient with alopecia areata led to significant hair regrowth and improvement in nail dystrophy symptoms, restoring finger function within 10 months.

This review discusses the use of dermabrasion as an effective skin resurfacing technique for treating aging effects and reports no new clinical results.

This article reviews historical cases and descriptions of perifolliculitis capitis abscedens et suffodiens, highlighting its characteristics and treatment, but reports no new clinical findings.

This review highlights the potential of microneedles as a low-cost, well-tolerated method for transdermal drug delivery in dermatology, though further research is needed to establish their clinical efficacy.

In this study, researchers found that parasitic dermatitis in dogs is predominantly caused by ectoparasites like fleas and mites, with flea allergy dermatitis being particularly prevalent, and noted that diagnosis typically relies on laboratory methods, while treatments involve insectoacaricidal drugs and prevention strategies.

This review found that anti-aging peptides show promise in cosmeceuticals due to their targeted actions to rejuvenate skin, but challenges like peptide stability, penetration, and limited clinical data limit their current effectiveness.

Cats with Feline Symmetrical Alopecia can regrow hair with proper treatment based on the specific cause, including diet, medication, or stress management.

This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.

This review discusses the protective and stress-buffering roles of melatonin in skin functions and structures but does not present new clinical findings.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

This article reviews the biological and physical principles of laser hair removal and reports that current laser systems do not consistently achieve permanent hair follicle destruction across treated areas.

This report concludes that the blend method is the most effective electrolysis technique for permanent hair removal, requiring proper technique and preparation such as shaving before treatment to increase efficacy.

This study found that a once-daily 5% minoxidil topical foam is as effective as a twice-daily 2% minoxidil topical solution for hair growth in women with androgenetic alopecia, with fewer side effects and greater styling convenience.

This review discusses evidence-based guidance for managing primary cicatricial alopecias but reports no new clinical results, highlighting significant gaps in knowledge and the need for more quality trials.

This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.

This review examines how mesenchymal stem cells and their derivatives may enhance skin regeneration and rejuvenation, but it reports no new clinical results; the authors suggest iPSC-derived MSCs hold promise for future therapies.

This review explores how androgens and growth hormone influence the development of terminal hairs and sebaceous glands, attributing variability in hirsutism and acne to differing genetic sensitivities to androgens, but reports no new experimental data.

This review discusses current knowledge on the biological mechanisms of different types of alopecia but reports no new clinical findings; the authors highlight future research directions, especially regarding epidermal stem cells and immune pathways.

This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.

This study analyzed skin from 538 knockout mouse mutants and identified 50 with epidermal phenotypes, providing valuable insights into genetic conditions and systemic effects related to skin abnormalities.

This review discusses the role of estrogens in hair follicle cycling and the skin, highlighting the need for more research on estrogen signaling pathways and their interactions with other factors in hair biology.

In this study, a methanol extract of Eclipta alba was found to have dose-dependent hair growth-promoting activity in C57BL6 mice.

This study reports that eccrine sweat glands in mice predominantly develop on the footpads, offering a reference for skin research involving genetically engineered mice.

This article reviews the basics of hair follicle biology, laser/tissue interactions, and hirsutism and hypertrichosis causes, discussing the long-pulsed alexandrite laser's role in hair reduction without reporting new clinical results.

This study found that macrophage-stimulating protein (MSP) enhanced hair growth in both human hair follicles cultured in vitro and in mice through the promotion of anagen phase induction.

In this study, mixing mouse epithelial and dermal cells was the most successful method for reconstituting hair follicles in mice, with the hair patch assay providing the quickest results.

This study found that alopecia in captive Rhesus macaques may be linked to chronic hypersensitivity dermatitis with CD4+ cell inflammation, possibly influenced by altered housing and reduced pathogen exposure.
