This study found that Ginkgolide B and bilobalide from Ginkgo biloba increased dermal papilla cell viability and promoted hair follicle growth in mink models by influencing signaling pathways.

In this case report, adult-onset porokeratotic eccrine ostial and dermal duct nevus improved with topical tazarotene treatment, as evidenced by dermatoscopic images.

This study found that adenine supplementation in cultured human follicle dermal papilla cells stimulated proliferation and reduced senescence, possibly through AMPK activation and increased cellular NAD+ levels.

This study found that papillary dermal fibroblast progenitors in newborn mouse skin can be isolated and cultured to generate male germline cell precursors, demonstrating their potential through differentiation into cells with meiotic capability.

In this study, researchers found that treating dermal papilla cells with synovial fluid and laser photobiomodulation increases the expression of chondrocyte marker genes, indicating potential promotion of chondrogenic differentiation.

This study found that topical melatonin significantly improved hair density and reduced the severity of androgenetic alopecia in men and women.

This review reports on the dual aspect of fullerene in skincare, highlighting its beneficial antioxidant properties as well as potential toxicity and skin cell reactions, while identifying areas for future research.

This study suggests that novel lipid nanoparticle formulations may be suitable for delivering anti-alopecia compounds like minoxidil and finasteride, although their skin penetration was limited.

This review describes ethosomes as promising nanocarriers for delivering active cosmetic ingredients to the skin, potentially transforming treatments for hair loss, acne, and skin pigmentation.

In this study, researchers found that a scallop adhesive protein (Sbp9 Δ) forms strong adhesive coatings via disulfide-sticker strategies, which also promote hair regeneration in mouse models by activating Wnt signaling and enhancing angiogenesis, proving more effective than minoxidil for androgenetic alopecia.

This study found that bioelectric and biochemical signaling mechanisms coordinate collective cell movement during chicken feather bud morphogenesis, suggesting a potential new angle for research in skin development and wound healing.

Equol may help with antiaging and skin health by boosting collagen and blocking certain hormones.

This review discusses the potential of microneedles to enhance transdermal drug delivery by expanding the range of deliverable drugs, highlighting fabrication methods, material choices, and applications, but notes existing challenges with sustained delivery, cost-effectiveness, and large-scale production.

In a C3H mouse model, this study found that topical retinoids can significantly alter hair-cycle dynamics by prolonging the anagen phase and shortening the telogen phase, a reaction connected to increased cellular retinoic acid-binding protein levels.

This review discusses micro needling as a therapeutic option for various dermatological conditions, such as scars and pigmentation, and reports no new clinical results; the authors note potential side effects and contraindications.

This study found that a 16-week dermal application of rice bran extract significantly increased hair density and diameter in male androgenic alopecia patients without causing adverse reactions.

This study found that intradermal administration of adipose-derived stem cell–conditioned medium significantly increased hair density and dermal thickness, suggesting potential regenerative effects on both hair follicles and the interfollicular scalp in patients with alopecia.

This review discusses various microneedle technologies for long-acting drug delivery, highlighting design considerations and challenges in bringing these minimally invasive devices to market, but it reports no new clinical results.

This letter to the editor references a study on using dihydrotestosterone gel before hypospadias surgery but itself contains no new findings.

This study found that 17-beta-estradiol inhibits hair growth in mice by blocking hair follicles in the telogen phase, whereas an estrogen receptor antagonist promotes hair growth by initiating anagen.

This review discusses the use of dermal regeneration templates for treating burn injuries and other wounds, highlighting their effectiveness in reducing scars and aiding in regenerative processes, but reports no new clinical results.

This study found that placental growth factor (PlGF) enhanced hair shaft elongation and accelerated hair follicle growth, suggesting its potential as a therapeutic target for alopecia.

This study found that topical application of N,N-dimethylglycine sodium salt increased dermal blood flow and velocity in human subjects, likely through its effects on endothelial cells and NO-dependent vasodilation.

A 2 mm needle is effective and precise for skin injections.

This chapter reviews common cosmetic dermatology techniques but presents no new findings; it discusses treatments like emollients and laser therapy for conditions like photoaged skin and acne scarring.

In this correspondence, an observed pattern of significant hair shedding occurred four to six weeks after women discontinued chorionic gonadotropin and a 400-calorie diet, ruling out other common causes of telogen effluvium.

This study suggests that macrophages, particularly CD206⁺ macrophages, play a crucial role in squaric acid dibutylester-induced hair growth in alopecia areata treatment.

This study observed that exosome treatment in skin led to increased dermal vascularity and mild inflammation, with one alopecia patient showing hair follicle growth at treated areas.

This study aimed to enhance the skin penetration of brown algae fucoidan using a Nanostructured Lipid Carrier, achieving a formulation with good physical quality and stability.
