This review describes minoxidil's hair regrowth mechanism and discusses dermatological applications, but reports no new clinical results, emphasizing the need for regular use and addressing allergic reactions.

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

This review discusses the relationship between estrogen deficiency and skin aging in postmenopausal women, noting potential benefits of estrogen use on skin collagen and elasticity, but reports no new clinical results.

This article reviews treatment options for androgenetic alopecia and suggests that therapy should be personalized and targeted at various pathophysiological aspects, but reports no new clinical findings.

This review discusses the effects of oestrogen on skin ageing and highlights the need for large-scale clinical trials to evaluate postmenopausal oestrogen use, reporting no new findings.

This study suggests that minoxidil is a potent stimulator of elastin expression in embryonic skin fibroblasts, primarily affecting elastin mRNA levels, without impacting cell proliferation during the stationary phase.

This review focuses on the roles of amino acids, peptides, and proteins in cosmetics, highlighting their importance in skin health and their potential for development in personal care products due to their unique properties and biocompatibility.

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.

This study found that a topical lotion containing minoxidil, hydrocortisone butyrate, and 17α-estradiol improved or stabilized frontal fibrosing alopecia in 35 out of 40 women over 36 months.

This research concluded that the novel hydrogel PlacMA, derived from human placenta and curable by visible light, shows promise for cell culture and tissue engineering applications due to its tunable properties.

Modified HDL can better deliver drugs and genes, potentially improving treatments and reducing side effects.

This review explores the role of advanced glycation end products in skin aging and their interaction with oxidative stress, but reports no new clinical findings.

Botanical extracts are increasingly important in cosmetics and drugs for their effectiveness and safety, backed by traditional use and scientific evidence.

This symposium abstract reports no new experimental results and discusses the pathophysiology of hair growth as presented at an event organized by the Institute of Dermatology.

This study identified multiple loss of function variants in the HR gene linked to the unique hair coat phenotype in lykoi cats, also known as werewolf cats.

This study found that the alkaline degradation process of hair keratin using nucleophilic reagents led to different proportions of reaction products compared to wool, particularly more lanthionine and lysinoalanine residues.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

This study in diabetic db/db mice found that treatment with the antihypertensive agents minoxidil or nebivolol stimulated elastogenesis and inhibited elastolysis, leading to restored elastic fibers, reduced aortic stiffening, and normalized blood pressure.

In this placebo-controlled clinical study, a cream containing 4% capryloyl glycine and 1% glycine soy‐fermented extract effectively inhibited ODC1 activity and improved hypertrichosis in 91.7% of Caucasian female patients on the forearms, whereas no improvement was observed with the placebo.

This study demonstrated that keratin can be effectively extracted from wool using alkaline solutions and that the extracted keratin maintains reactivity similar to that from other low-value sources like cattle hair.

This study compared hydrolysed wheat protein, L-arginine, and hydrolysed collagen for their effectiveness in enhancing the tensile strength of heavily bleached hair.

In this study, injecting Nε-(carboxymethyl) lysine into skin tissue weakened hair shaft and follicle formation, likely by inhibiting cell proliferation and migration needed for hair follicle morphogenesis.

Hair fibers may have a unique, non-protein sheath not previously identified.

This study identified that a deficiency in the palmitoyl transferase enzyme, due to a mutation in the Zdhhc13 gene, led to severe physiological abnormalities in mice, including skin, bone, and systemic amyloid issues.

This study identified a sulfotransferase activity in rat liver that catalyzes the sulfation of minoxidil, contributing to its delayed hypotensive effects.

This study found that ZDHHC13 deficiency in mice is associated with abnormal liver function, lipid metabolism issues, and impaired mitochondrial function, highlighting ZDHHC13's regulatory role in liver metabolism.

This study observed that the ethyl acetate extract of Equisetum debile showed high activity against 5α-reductase and lipid peroxidation with no cytotoxicity on dermal papilla cells.

Human enzymes can detoxify harmful substances but might also increase their cancer risk.

The study found that melatonin treatment in early postnatal cashmere goats increased both the quantity and quality of cashmere by promoting secondary hair follicle development and enhancing antioxidant enzyme activities.

This review suggests that skin may largely protect itself from CYP-generated reactive metabolites due to higher conjugating enzyme activities, while highlighting limitations in modeling human skin metabolism experimentally.
