This study found that overexpression of activin in transgenic mice led to enhanced granulation tissue formation after skin injury due to changes in keratinocyte proliferation and differentiation.

This review examines hair cosmetics, including shampoos and conditioners, for their formulations and effects, but reports no new clinical findings; it emphasizes the importance of dermatologist knowledge in treating diverse hair conditions.

This review discusses strategies for developing semi-solid topical generic products to match the quality of reference-listed drugs, using concepts like quality by design and reverse-engineering, but reports no new results.

This study reported that finasteride 1 mg/day significantly increased hair growth and slowed hair loss in men with frontal scalp hair thinning over one year, and these benefits continued or improved in the second year.

This study introduces a novel non-invasive method called "differential stripping" to quantify the penetration of topically applied substances into hair follicles.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This review discusses the use of caffeine in cosmetics for its fat-reducing, antioxidant, and hair growth properties, but reports no new research findings.

This review discusses various nanoparticles and nanoemulsions being investigated for transdermal drug delivery and reports no clinical results; it highlights potential applications in treating alopecia, wound healing, psoriasis, and melanoma.

This review examines the role of hair follicles and sebaceous glands in percutaneous drug delivery but does not report new clinical results; it calls for further exploration of follicle-targeting therapies.

This review discusses how Western diet may contribute to acne vulgaris through insulin signaling and metabolomic changes, promoting a dietary approach for management, but reports no new experimental results.

This review discusses the classification, pathogenesis, and management of skin, hair, nail, and mucosal changes due to EGFR inhibitors, emphasizing the importance of informing patients to improve therapy compliance.

This review discusses various nanoparticles used to enhance skin permeation and target delivery to skin organelles, but reports no new experimental results.

This review provides an overview of scalp psoriasis treatments but presents no new clinical results; it highlights various options including coal tar, salicylic acid, corticosteroids, and vitamin D3 analogues.

This study found that in mice, dermal adipocytes initiate inflammation and aid repair after skin injury by releasing lipids, suggesting a role in managing inflammatory diseases and impaired wound healing.

This review discusses recent strategies targeting the neuroactive steroid biosynthetic pathway to enhance neurosteroidogenesis, highlighting their potential benefits for neurodegenerative and neuropsychiatric diseases, but reports no new clinical findings.

In this study, researchers found that in late pregnancy, the neuroactive progesterone metabolite allopregnanolone inhibits HPA axis responses to immune challenges via an opioid-mediated mechanism.

This review discusses the mechanisms and storage of particles in hair follicles and presents no new experimental results, highlighting the need for further research in their safe application in dermatology and cosmetics.

Minoxidil can help grow hair in mice by making cells grow and improving hair quality. More research needed.

This study shows that macrophage-induced TNF signaling can activate hair follicle stem cells and promote new hair follicle formation after wounding by regulating AKT/β-catenin pathways.

This review discusses the potential use of liposomal formulations to enhance the effectiveness of cosmeceutical delivery through the skin barrier, with no new clinical results reported.

This review discusses current treatment challenges and strategies for managing psoriasis in the scalp, nails, and intertriginous areas, emphasizing the need for effective and well-tolerated long-term options, but reports no new clinical results.

This study found that carbon nanotube impurities induced immunological toxicity in mice, whereas purified nanotubes showed good biocompatibility, suggesting high-temperature thermal treatment may improve nanotube biocompatibility.

This systematic review reports that "COVID toes" and other skin manifestations can be initial signs of COVID-19, and advises immunosuppressive therapy adjustments only for infected or at-risk patients.

This study found that the nanostructured lipid carrier gel containing minoxidil showed good consistency and a prolonged drug release in vitro, suggesting potential for treating alopecia.

This study concluded that epidermal growth factor may induce a 'catagen-like' phase in human hair follicles by disrupting normal cellular proliferation and migration patterns.

This review describes recent advances in using nanoparticles for drug delivery to hair follicles, with potential applications in treating skin diseases such as alopecia and acne, but reports no new findings.

This study found that 2% ketoconazole shampoo improved hair density and anagen follicle proportion in androgenic alopecia similarly to minoxidil treatment, suggesting a potential role for Malassezia in inflammation.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This review discusses the current research and development of mannosylerythritol lipids, particularly focusing on their potential commercial applications in cosmetics; it reports no new results.

This study found that combining oral finasteride with topical minoxidil resulted in the greatest improvement in hair growth for male patients with androgenetic alopecia, compared to using any single treatment.
