This review discusses the effects of estrogens on skin aging and highlights the potential benefits of estrogen replacement therapy and selective estrogen receptor modulators for improving skin health in postmenopausal women, but reports no new clinical findings.

This study found that using a low-level laser comb led to hair regrowth in a mouse model of alopecia areata, while sham-treated mice showed no hair regrowth.

This study suggests that a position effect disrupting TRPS1 expression may be linked to hypertrichosis in both Ambras syndrome in humans and a similar phenotype in Koa mice.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

This study found that aged tritiated thymidine breaks down and incorporates into cytoplasmic macromolecules, not DNA, suggesting caution in its use.

This study found that nanostructured lipid carriers with clobetasol propionate significantly enhance follicular drug delivery compared to commercial cream, and manual massage further doubles follicular retention.

This article discusses the distribution of extracellular matrix molecules in human hair follicles and reports no new results.

This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.

This study found that enhanced expression of the Sonic hedgehog gene via an adenovirus vector accelerated hair regrowth in mice with chemotherapy-induced alopecia.

This study found that hair follicle stem cells could enhance burn wound healing and improve tissue tensile strength in rats.

This review suggests that while NSAIDs may inhibit bone healing and have variable effects on other complications, caution is advised in their prescription post-surgery, particularly for female patients.

Minoxidil improves blood flow and vessel flexibility, potentially helping with vascular stiffness.

This study found that cooling hair grafts during transplantation did not significantly improve the survival or growth rates of hair follicles compared to room temperature storage.

This study found that Ishige sinicola extract increased hair growth and cell proliferation in cultured vibrissa follicles and mice, suggesting potential benefits for treating alopecia through β-catenin activation and 5α-reductase inhibition.

This study suggests that sinapic acid may promote hair growth in human hair follicle dermal papilla cells by activating specific signaling pathways and inducing the expression of growth factors.

This review discusses the potential of ozone therapy as an adjuvant to radio-chemotherapy for cancer patients, noting enhanced treatment effects and improved quality of life, but it presents no new research findings.

In this study, intradermal injections of autologous platelet-rich fibrin matrix significantly increased hair density in patients with androgenetic alopecia at 2 and 3 months after initial treatment.

This study found a strong correlation between antioxidant activity and phenolic content in rosemary, influenced by bioclimatic and seasonal factors in different stages of Tunisia.

This study suggests that finasteride may affect hair follicle growth by altering the expression of caspases and XIAP, potentially regulating the anagen phase of hair growth.

This study found that procyanidins effectively alleviate neuropathic pain in mice by significantly inhibiting MMP-9/2 activity.

This study reports that finasteride treatment in men with androgenetic alopecia appears to restore caspase and XIAP expression in hair follicles to levels similar to those in individuals without the condition.

This study showed that chemical and mechanical treatments significantly alter the nanoscale surface properties of hair, affecting its roughness, mechanical stiffness, adhesion, and surface potential.

This study found that dihydrotestosterone (DHT) may shorten the hair growth cycle through mechanisms like cell-cycle arrest and β-catenin downregulation in rat hair follicle cells.

This review discusses environmental factors like UV radiation and smoking that affect hair health and highlights the potential role of nutrition, but it reports no new results.

Anticonvulsant drugs may cause temporary chromosomal abnormalities.

This research found that a biodegradable fibrous membrane incorporating fibroblast-derived ECM accelerated wound healing and improved neovascularization in a mouse model.

This study found that fig leaf extract significantly downregulated inflammatory and androgenic gene expression in vitro, suggesting potential topical benefits for certain skin disorders.

This study reported that Panax ginseng extract significantly inhibited DKK-1-induced catagen-like changes in human hair follicles by promoting cell proliferation and reducing apoptosis, suggesting it may help mitigate hair loss associated with DKK-1.

This study concludes that egg shell membrane hydrolysates, particularly Fraction I, may effectively mitigate UV-B radiation-induced wrinkles and promote skin collagen and hyaluronic acid production, suggesting potential use in functional cosmetics.

In this study, human placenta extract was observed to enhance the hair-growth-promoting effects of minoxidil and stimulate earlier and prolonged anagen phases in a mouse model.
