This study found that arginine-loaded lipidic nanoparticles improved hair follicle growth in male hamsters more effectively than an aqueous arginine solution.

This study found that a papain-containing cream had a significantly greater depilatory effect and altered skin morphology more than a papain-containing gel when applied to mice.

Plasma as a graft holding solution improves hair transplant results by increasing graft survival and promoting hair growth.

This study observed that keratin sponges showed comparable biocompatibility to a commercial positive control in mice, but keratin gels had slightly inferior biocompatibility.

This study demonstrated that prolonged use of commercial hair dyes caused significant increases in liver enzymes and bilirubin levels, and evident cellular injury in the skin and liver tissues of Albino rats, indicating potential toxicity.

This study found that platelet-rich plasma treatment improved wound healing in both diabetic and non-diabetic rat tongue wounds, particularly when applied before injury.

This study found that in male rats, finasteride significantly decreased spermatogonia and primary spermatocytes numbers and increased Leydig cells, but did not affect overall testis histology or spermatogenesis.

In this controlled study on hair transplantation, using autologous plasma as a graft holding solution resulted in better hair follicle cell survival, hair count, and density compared to Ringer's lactate, suggesting plasma's potential to enhance hair graft outcomes.

In this study, researchers observed significant morphological and histological differences in transplanted hair follicles compared to native donor follicles post-FUE hair transplantation for androgenetic alopecia, highlighting substantial variations in sebaceous gland and root sheath degeneration at the recipient site.

In this pilot study, researchers observed a correlation between clinical severity and histologic severity of lichen planopilaris, suggesting that an immunohistochemical scoring system could aid in grading disease activity.

This study observed an increase in hair thickness and reduced hair loss in patients with androgenetic alopecia after treatment with autologous cellular suspension using the Rigenera® system, though further research is needed.

In this study, dogs with hair cycle disorders, especially those with alopecia X, showed a significant increase in the number of kenogen follicles, suggesting impaired induction of new hair growth phases.

This study found that pigmentation following sclerotherapy is likely caused by hemosiderin deposition from red blood cells rather than post-inflammatory hyperpigmentation, with most cases resolving spontaneously within 6–24 months.

This study observed that both TCA (35%) and GA (70%) chemical peels improved skin morphology and stimulated bulge stem cells in albino rats, with no significant difference between the two agents.

This article reviews advances in the histologic evaluation of alopecia and hair-related disorders, without presenting new clinical results.

This study concluded that a single injection of platelet-rich plasma can enhance wound healing in both diabetic and non-diabetic oral mucosal tissues in rats.

This research found that crude leaf extracts of Calotropis gigantea caused significant oxidative stress and cellular damage in freshwater fish Danio rerio over 30 days, highlighting the toxicological risks of this plant despite its medicinal properties.

This study found that microneedling with growth factors improved collagen production and connective tissue reorganization more than microneedling with saline in facial rejuvenation.

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 study found that IPL hair reduction led to significant decreases in hair count and thickness by promoting hair follicle miniaturization, increased telogen phase, and reduced cell proliferation.

In this study, researchers reported that standardized rosemary and capsicum extracts significantly improved hair growth parameters such as follicle density, length, and diameter in rats with testosterone-induced alopecia, suggesting these extracts may aid in more effective natural treatments for androgenetic alopecia.

Caffeine and siloxanetriol alginate caffeine in emulsion form can reduce fatty cell size and number, potentially treating cellulite effectively.

This study developed a caffeine-loaded solid lipid nanoparticle gel, observing significant reduction in subcutaneous fat tissue thickness in histological tests compared to an untreated group, suggesting it could effectively treat cellulite as a promising nanocosmeceutical gel.

This review presents an objective analysis of female androgenetic alopecia, discussing clinical and dermoscopic examination approaches but reports no new clinical findings.

Dermoscopy is a good, noninvasive way to see normal cat skin structures and could be useful for check-ups.

This study found that Quantitative Mass Spectrometry Imaging offers precise localization and quantification of active compounds in skin tissues, demonstrating benefits over traditional LC-MS in drug penetration studies.

This study found that low-level laser therapy with an 830-nm wavelength most significantly stimulated hair growth in rats, compared to other wavelengths tested.

In this study, lecithin-based microparticle formulations of minoxidil showed enhanced skin penetration and comparable hair growth effectiveness to commercial products in mice, while minimizing skin irritation often seen with standard minoxidil solutions.

This review discusses techniques and models for assessing hair growth activity but reports no new clinical findings, emphasizing the need for standardization and improved animal models.

This case report describes the co-occurrence of alopecia areata and psoriasis in an 18-year-old girl with Turner's syndrome, suggesting a potential genetic link to immunological diseases in these patients.
