This study found that polycaprolactone (PCL) in facial fillers led to more cell proliferation and vascular activity than hyaluronic acid (HA) in Wistar rats, suggesting enhanced tissue regeneration effects with PCL.

This study found that a single session of botulinum toxin, whether administered subcutaneously or combined intramuscularly and subcutaneously, did not significantly improve hair density or hair quality in men with androgenetic alopecia after six months.

The study did not find evidence to support using botulinum toxin as a treatment for androgenetic alopecia.

This review discusses the possible materials used in subcutaneous injections for alopecia, but it reports no new clinical results and highlights the need for further research.

This case report describes subcutaneous emphysema in a patient's forearm as a rare complication of liquid nitrogen spray used on hypertrophic actinic keratosis, resolving spontaneously within a day.

This review discusses the role of dermal papilla cells in hair follicle formation and their potential use in cell therapy for hair loss, but reports no new research findings.

This review discusses the diagnostic classification and traditional Korean medicine treatments for abnormal hair growth and reports no new clinical results; it suggests that combining these with modern technology may enhance cosmetology advances.

This research found that keratin hydrogels derived from human hair may support cell viability and proliferation, indicating potential as 2D and 3D soft tissue culture scaffolds.

In this study, Lespedeza bicolor extract was found to enhance dermal papilla cell proliferation and extend the anagen phase in mice, suggesting its potential as a treatment for alopecia.

Antiyeast treatments work better for seborrheic dermatitis than steroids, and other findings include increased skin bacteria under plastic wrap, a nasal cell defect in Staphylococcus aureus carriers, quick resolution of certain skin reactions, high rubber latex allergy in spina bifida patients, and glyceryl monopentadecanoate's effectiveness for male hair loss.

This study found that melanocyte progenitor cells are present in human subcutaneous adipose tissue and may differentiate into mature melanocytes, suggesting potential applications in treating skin diseases and rejuvenation.

This study observed that multiphoton excitation microscopy revealed changes in vascular structure and hair papillae in mice subcutaneous tissue following cyclophosphamide treatment for chemotherapy-induced alopecia.

In this study using female mice, researchers observed that topical application of 20% whale oil was more effective in promoting hair growth compared to a standard 3% minoxidil solution, with additional findings suggesting reduced stress- and inflammation-related responses with whale oil.

This study demonstrated that quercetin effectively treated alopecia areata and prevented its onset in a mouse model, suggesting potential for clinical applications in managing the condition.

This study evaluated two bimatoprost 1% formulations for androgenetic alopecia in men, finding both formulations achieved effective drug concentrations in the scalp with no significant differences between them, and were well tolerated over the 14-day application period.

This review discusses recent advances in noninvasive hair imaging technologies, such as global photography, trichoscopy, reflectance confocal microscopy, and optical coherence tomography, highlighting their potential to improve hair diagnostics and treatment monitoring, while also outlining their clinical applications and limitations.

In this study using rat models, researchers found that subcutaneously implanted non-de-epithelialized flaps maintained persistent epidermal components, leading to potential complications, whereas de-epithelialized flaps showed gradual regression of remaining skin elements, lowering complication risks over time.

This review discusses the potential esthetic applications and regenerative properties of adipose-derived stem cells but reports no new clinical findings, emphasizing the need for further research to establish efficacy.

This analysis found that mesenchymal stem cell-derived exosomes show potential as a safe and effective treatment for various skin and subcutaneous tissue diseases.

This study suggests that topical procyanidin B-2 is safe for use as a hair growth agent, as it showed no mutagenic effects or significant irritation in a series of toxicological tests.

This review discusses developments in tissue engineering for burn wound coverage and reconstructive surgery, reporting no new results but highlighting the need for further research into clinical effectiveness.

This study found that cyclosporin A treatment in young nude mice induced dose-dependent hair growth, which stopped after treatment cessation, but did not result in hair growth in older mice.

This study found that localized administration of heat or certain stress protein inducers effectively prevented chemotherapy-induced hair loss in rodent models without affecting chemotherapy efficacy.

This study reviewed literature from 1992 to 2018 to document mesotherapy-related complications and their management, concluding that standardized therapy parameters are needed to better evaluate the safety profile and minimize risks of adverse reactions.

This study found that flumethasone administration in Merino wethers led to variations in wool shedding and initial reductions in wool growth, with full recovery generally observed within 60 days post-treatment.

This study found that subcutaneous injection of medroxyprogesterone acetate was more effective than intramuscular or topical treatments in reducing hair diameter for hirsute females.

This review outlines the histological structures of the skin, highlighting species and regional differences in dermal absorption and obstacles encountered in toxicological assessments due to epidermal thickness variability, contact dermatitis reactions, and stem cell vulnerabilities.

This study found that keratin scaffolds derived from human hair promoted excellent cell viability and showed minimal inflammatory response and vascular integration when tested in in vitro and in vivo settings.

This study found that Botox® was most effective at a 25 U/ml concentration, while Dysport® and Neurobloc® were optimal at 100 U/ml for producing anhidrotic areas after injections.

This article describes mesotherapy, a technique involving small doses of compounds injected into the skin for cosmetic uses like aging skin and fat reduction, and provides no new clinical results.
