This study suggests that a mixture of 5‐ALA and iron ion significantly improved hair growth in mice, comparable to minoxidil, without promoting keratinocyte or fibroblast proliferation in vitro.

This study found that 10% Citrus aurantium peel oil significantly promoted hair growth in ICR mice by reducing the time needed for hair growth initiation and completion, and by increasing hair length, follicle diameter, and count, showing potential as a hair growth agent.

Certain ingredients can help protect hair color.

This study suggests that StemMACS MSC Expansion Media is more suitable than PowerStem MSC1 media for expanding therapeutic adipose-derived mesenchymal stem cells, with less expression of negative markers and better chromosomal stability.

Hair is thinner near the scalp in acute hair shedding conditions.

This study found that factors released by mesenchymal stromal cells can enhance the proliferation and migration of keratinocytes in vitro, which may contribute to improved understanding of their role in wound healing and potential applications in dermal regeneration therapies.

In this study, researchers evaluated the effects of green spinach leaf extract on hair growth in New Zealand rabbits and found that the 15% concentration formula resulted in the highest average hair growth compared to other concentrations and controls.

This review discusses the steroidogenic properties of human skin and suggests that impaired steroidogenesis may be linked to conditions like acne, rosacea, atopic dermatitis, and androgenic alopecia, but reports no new clinical results.

This study found that wire brush hair snares collected the most hair from Eurasian Lynx in controlled enclosures, suggesting potential for sampling genetic material from similar felid species.

This study found that finasteride and melengestrol acetate exhibit varying levels of toxicity to freshwater mussels, amphipods, and mayflies, but current environmental concentrations suggest minimal direct effects on these aquatic invertebrates.

This study found that patients with BPH who received finasteride before TURP experienced reduced intraoperative blood loss and improved quality of life one month after surgery compared to those who did not.

This study found that various reduced folates effectively penetrated an in vitro skin model, promoted cell proliferation and migration, and may enhance wound healing, suggesting potential for topical treatment in skin conditions.

This study concluded that selenium supplementation for ovarian cancer patients during chemotherapy may have several beneficial effects, such as increased antioxidant enzyme activity, reduced chemotherapy-related symptoms, and higher selenium levels in serum and hair.

Finasteride affects male rat genitalia development, causing abnormalities during specific pregnancy days.

This study developed minoxidil sulphate-loaded chitosan nanoparticles that doubled drug delivery to hair follicles in vitro compared to a control solution, suggesting potential for improved alopecia treatment.

This study examined different polymersome systems for topical finasteride delivery and found that chitosan-decorated C7 polymersomes may enhance skin retention and provide controlled drug release compared to non-decorated systems in laboratory settings.

This study observed that Ptprq mutant mice exhibit significant abnormalities in hair bundle structure and vestibular dysfunction, suggesting similar issues may contribute to hearing loss and vestibular problems in humans with PTPRQ mutations.

This study observed that long-term use of finasteride in Japanese men with androgenetic alopecia was associated with progressive hair regrowth in 87.1% of participants without significant safety concerns.

High doses of finasteride cause cell growth and tumors in mice.

This study found that acute sleep deprivation enhanced 5α-reductase expression and activity in the rat prefrontal cortex, and finasteride treatment reduced associated psychosis- and mania-like behaviors.

Martin-Perez et al. show that rapamycin's beneficial effects in a mouse model of Leigh syndrome are linked to the downregulation of protein kinase C.

This study found that finasteride impaired stress reactivity and reduced exploratory and impulsive behaviors in rats, potentially by altering the hypothalamus-pituitary-adrenal axis function.

In this laboratory study with rats, treatment with finasteride reduced dihydrotestosterone levels and fertility parameters, with a 30-day recovery period proving insufficient to fully restore sperm function and fertility.

The researchers reported that among Mediterranean Sicilian women with PCOS, Phenotype B exhibited the most severe metabolic abnormalities, notably obesity and altered glucose metabolism, whereas Phenotype D showed no such issues.

This study found that finasteride significantly reduced levodopa-induced dyskinesia in both male and female rats without diminishing l-DOPA's motor benefits, indicating potential for clinical trials in Parkinson's patients.

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.

This study identified significant changes in the expression of nine proteins in the nucleus accumbens of rats treated with finasteride, suggesting potential novel targets for its neuropsychiatric effects.

In this study using a mouse model, ECM/SVF-CM, derived from adipose-derived stem cells, was observed to stimulate hair growth more effectively than SVF-CM by promoting cell proliferation, neovascularization, and anagen induction, which may support its potential as an improved treatment for hair loss.

In this study, ethanamizuril was found to cause alopecia, biochemical changes, and organ damage at higher doses in rats, with a no-observed-adverse-effect level of 20 mg/kg over 30 days.

This study found that early-onset androgenetic alopecia, especially with a vertex pattern, may be an independent risk factor for cardiovascular disease and metabolic syndrome in men.
