This study found that in bovine skin, leptin and its receptor are expressed in the epidermis and hair follicles, suggesting a role in epidermis growth and hair follicle cycling through paracrine and autocrine mechanisms.

This study used melamine formaldehyde particles to measure a pH gradient along the hair shaft, showing a significant pH decrease from the hair sheath to the external shaft.

This study found that keratin-associated proteins form part of the developing exocuticle and a-layer in hair fiber cuticle cells, while cornified envelope proteins were absent.

This study found that human hair follicle-derived mesenchymal stem cells effectively maintained human embryonic stem cells in an undifferentiated state, comparable to mouse embryonic fibroblasts under standard conditions.

This study supports using mesenchymal stem cells cultured with collagen to accelerate skin wound healing in mice and canines, by enhancing epidermal repair and promoting factors essential for skin recovery.

In this study, researchers successfully constructed a high-precision three-dimensional model of human skin dermis, revealing a detailed analysis of dermal porosity and pore diameter distribution, which can aid the development of biomimetic tissue-engineered skin.

This study identified a unique concentric double-layered structure in both Japanese and Caucasian SHINAYAKA hair, associated with improved flexibility and elasticity, and developed a succinic acid treatment to enhance these properties.

This review discusses various methods for processing and separating human skin samples for research purposes, evaluating factors like processing time and cell viability, but reports no new experimental findings.

In this study, researchers developed a DNA/GelMA-based cryogel platform that uses phototherapy to combat MRSA infection and promote scarless wound healing, showing enhanced bactericidal activity, tissue regeneration, and anti-inflammatory effects in vivo, suggesting a promising approach for treating infected skin wounds.

This review concludes that low-level laser therapy is the most supported physical treatment for androgenetic alopecia, but other therapies like nonablative laser treatments and combinations including PEMF may also be promising.

In this animal study, researchers found that the simultaneous deletion of ERBB2 and ERBB3 in mice results in impaired skin differentiation, inflammation, and sebaceous gland alteration, leading to skin lesions, while highlighting potential side effects in cancer therapies targeting these receptors.

In this study, a combined rosemary and neem extract outperformed ketoconazole and minoxidil in treating dandruff, scalp disorders, and promoting hair growth, demonstrating potent antifungal and anti-inflammatory properties in lab settings.

In this study, researchers developed self-assembled skin models derived from hair follicle cells, offering an ethical and reliable alternative to animal testing and bovine collagen in dermatological research by providing functional dermal and epidermal layers for substance evaluation.

This study reviewed evidence suggesting that certain types of wounds might stimulate localized hair growth in humans, noting anecdotal reports and mixed efficacy of treatments like microneedling and lasers for androgenetic alopecia, but emphasized that further research is needed.

This study examined the age-related changes in the dermal structure of goat skin, providing baseline data on its histomorphology, histochemistry, and histoenzymology.

This study found that the dual-wavelength non-ablative fractional laser provides enhanced skin rejuvenation by increasing thermal lesion coverage and collagen remodeling compared to using the CO2 laser alone in an ex vivo setting.

This review discusses low-level laser therapy and fractional laser therapies as alternative treatments for androgenetic alopecia, but reports limited evidence of their efficacy due to small sample sizes and potential study biases.

This study found that combining fractional laser therapy, intravenous blood irradiation, and minoxidil significantly improved the psycho-emotional state and quality of life in patients with diffuse telogen effluvium, performing better than individual treatments alone, as measured by the DIQOL index.

This source explores the causes, diagnosis, and treatments of telogen effluvium, highlighting literature on injection and hardware therapies, including fractional laser therapy, and describes various mechanisms through which physical factors exert therapeutic effects.

This review synthesizes evidence on platelet-derived bioproducts like PRP and PRF, highlighting their role in tissue regeneration and their benefits in aesthetic medicine applications such as hair restoration, scar treatment, and wound healing.

This study found that commercially available dyes penetrate up to 1.2 mm into human skin, with Indocyanine Green binding to cell proteins and showing a shift in absorption peak.

This article highlights that hormonal changes during menopause can significantly affect hair health, leading to decreased hair density, altered texture, and increased hair disorders, which may subsequently impact emotional well-being in women.

This study reports that human hair follicle stem cells express different surface markers than mouse stem cells, facilitating their isolation and potentially aiding in the development of cell-based skin treatments.

This review of acne management strategies highlights current treatments, such as topical and systemic therapies, procedural methods, and dietary changes, while also discussing emerging options like biologics and probiotics as potential future treatments, emphasizing personalized care due to acne's complex nature.

This study found that mesenchymal progenitor cells from human hair roots seeded onto polymer scaffolds stimulated the production of mineralized proteins, enhancing bone-like structures, with optimal results at a pore size of 35 µm.

This study found that nanofibers combining a polydopamine coating and curcumin nanocrystals were effective in treating diabetic wounds infected with methicillin-resistant Staphylococcus aureus by providing sequential photothermal antibacterial action and promoting M2 macrophage polarization, which accelerated wound healing through enhanced angiogenesis and cell proliferation.

This review discusses the use of aesthetic treatments for medical purposes and their therapeutic potential but provides no new clinical results.

This study reviewed eight studies investigating transcutaneous drug delivery via fractional laser and microneedling for alopecia treatment, with six studies showing improved hair regrowth over topical therapy alone, suggesting its potential as a promising treatment strategy, although further research is needed to refine treatment parameters.

This case report details a rare instance of eruptive vellus hair cysts in a 12-year-old male, highlighting its atypical morphology and axillary distribution, which has not been previously documented.

This study developed a straightforward HPTLC method for detecting nicotine and cotinine in human plasma and urine, concluding that liquid-liquid extraction with methanol: chloroform: ammonia achieved optimal separation and is applicable for forensic analysis of lethal nicotine intoxication.
