This study reports that hair growth and shedding in healthy women show annual seasonal patterns, with the highest shedding in summer and a less pronounced peak in spring.

This study found that mechanical stress activates a WISP-1/Hedgehog signaling axis that contributes to ligamentum flavum hypertrophy and fibrosis, identifying Hedgehog signaling as a potential therapeutic target.

This review explores research on nanoformulations for enhancing the topical delivery of herbal medicines, noting potential benefits like improved bioavailability and sustained delivery, and emphasizes the need for safety and toxicity guidelines in developing these novel drug delivery systems.

This study demonstrated that keratin derived from human hair can improve axon extension and alleviate motor deficits from sciatic nerve injuries, highlighting its potential as a promising biomaterial for peripheral nerve regeneration.

This study found that the 11R-No. 10 peptide, delivered transdermally, significantly inhibited melanogenesis and produced a whitening effect in a UV-induced sun-tanning guinea pig model without cytotoxicity.

This narrative review discusses the structure and functions of the skin, focusing on its barrier role, self-repair, thermoregulation, and immune functions, and reports no new experimental results.

Tiny particles carrying roxithromycin can effectively target and deliver the drug to hair follicles without irritation.

This study found that in androgenic alopecia, the arrector pili muscle degenerates and is replaced by fat, unlike in normal skin or telogen effluvium.

This report describes a case of meningioma in a transwoman treated long-term with estradiol and cyproterone acetate, suggesting possible concern over female sex steroids and meningioma risk.

This study found that 4-MA is a potent inhibitor of testosterone 5α-reductase in human tissues, promising potential for treating androgen-dependent skin conditions like male pattern baldness.

This study found that cepharanthine can inhibit gastric cancer cell activity by inducing oxidative stress and altering energy metabolism, suggesting its potential for gastric cancer treatment.

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 study found that human hair follicle dermal cells, specifically dermal sheath cells, can serve as an alternative and potentially superior cell source for constructing the dermal component of bioengineered skin in both in vitro and in vivo settings.

This study found that the sebum partition coefficient (K(sebum)) for some drugs differs from the stratum corneum partition coefficient (K(sc)), indicating its importance for targeted drug delivery into hair and sebaceous follicles.

This review compiles studies on the antidiabetic potential of plants from the Middle East, particularly from the Asteraceae and Lamiaceae families, but reports no clinical results.

This study found that pharmacological inhibition of sex steroid synthesis impacts pathogenic processes in traumatic brain injury in a sex-specific manner, with distinct effects of letrozole and finasteride on molecular and neurological outcomes.

This study found that nanostructured lipid carriers enhanced the skin penetration and retention of minoxidil compared to solid lipid nanoparticles, suggesting they could be a promising method for topical delivery.

This study found that combining minoxidil and retinol additively promoted hair growth in vitro, enhancing Erk- and Akt-dependent pathways and preventing apoptosis in dermal papilla cells and keratinocytes.

In this study, an endoscopic midface lifting technique showed notable improvement in midface ptosis and infraorbital hollowing, with lower morbidity and few complications after over 400 procedures.

This study suggests that silver nanoparticles synthesized using Grewia optiva leaf extract exhibit stronger antibacterial and antioxidant properties than the leaf extract alone.

This study found that the human placenta extracellular matrix hydrogel restored the hair-inductive capacity of high-passaged dermal papilla cells, enabling them to regenerate new hair follicles when co-grafted with mouse epidermal cells.

This study found that human iPSC-derived melanocytes from vitiligo patients successfully integrated into mouse hair follicles and epidermis, demonstrating potential for personalized therapy for depigmentation.

This study found that mange-infected bare-nosed wombats have increased heat loss, higher metabolic rates, altered behavior, and disrupted fatty acid composition compared to healthy individuals.

This review discusses the role of microRNAs in skin function and potential therapeutic applications, emphasizing their importance in wound healing and disease management, though it reports no new experimental findings.

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 explored a keratin, sodium alginate, and carboxymethyl chitosan hydrogel modified with tannic acid and found it to have promising wound-healing qualities, including similar elasticity to human skin, antimicrobial and antioxidant properties, and effective water retention. These attributes suggest potential applications in biomedical engineering.

This review of stem cell-based tissue engineering treatments in preclinical burn wound models reports promising improvements in skin repair, suggesting potential as an enhanced therapy for burn wounds.

This study reports that miR-22 promotes cancer progression and metastasis by maintaining Wnt/β-catenin signaling and cancer stem cell function.

This study found that the PI3K-Akt signaling pathway is essential for regenerating new hair follicles when epidermal stem cells and skin-derived precursors are combined, suggesting potential therapeutic applications for hair regeneration.

This study found that BAF200, a subunit of the PBAF chromatin remodeling complex, is crucial for heart development and coronary artery formation in mice, as its absence led to embryonic lethality with severe cardiac defects.
