This review found that the ingredients of Keedari thailam, a traditional Siddha formulation used for alopecia areata, exhibit antimicrobial, anti-inflammatory, and other pharmacological activities, suggesting potential therapeutic benefits according to recent research and Siddha literature.

This study found that Dendrobium sabin flower extracts, especially the methanolic one, demonstrated strong antioxidant and anti-aging properties without significant toxicity, suggesting its potential in treating photo-induced skin aging.

In this study, Cyperus rotundus essential oil was found to have significantly better depigmenting effects than hydroquinone for treating axillary hyperpigmentation, with additional benefits in reducing inflammation and hair growth, making it a cost-effective and safe treatment option.

In this study, researchers developed a novel platform for discovering potential hair loss inhibitors by investigating the testosterone/dihydrotestosterone biosynthetic pathway and its regulation through biochemical mechanisms involving 17β-HSD and 3β-HSD, combined with medicinal plant extracts.

This study found that astaxanthin effectively protected human dermal papillae cells from oxidative stress induced by hydrogen peroxide, reducing the percentage of cells expressing a stress marker significantly, suggesting potential benefits for hair loss treatment related to reactive oxygen species.

This study showed that Thujae occidentalis semen extract inhibited 5alpha-reductase type 2 in laboratory tests and reduced androgen-related hair loss in animal models, suggesting potential use for male pattern baldness.

In this study, researchers optimized the extraction conditions for polyphenols from the medicinal herb Eclipta prostrata, achieving the highest polyphenol content under specific conditions of temperature, solvent concentration, and time, and found the extract to have significant antioxidant activity.

This study identified 92 novel regulators of melanogenesis, highlighting Aldehyde dehydrogenase 1A1 as a potential target for developing new treatments for hyperpigmentation disorders like melasma.

This study found that ursolic acid at 50 mg/kg improved biochemical, hormonal, and ovarian histopathological markers in a rat model of PCOS, suggesting its potential as a therapeutic option.

This study identified two major antibody-binding sites on tyrosine hydroxylase in vitiligo and alopecia areata patients, suggesting that their immune response is heterogeneous and can target multiple epitopes.

In this study, methanolic extracts of Hibiscus rosa-sinensis showed higher phenolic and flavonoid content, as well as greater concentrations of gallic acid and quercetin, than aqueous extracts, despite the latter yielding more extract, highlighting the effectiveness of methanol for extracting bioactive phytochemicals.

This study observed that the aqueous extract of roasted Alocasia macrorrhizos tubers led to hair follicle repigmentation and reduced epidermal thickness in a murine model of Vitiligo.

This study suggests that hydroxypinacolone retinoate (HPR) may be an effective alternative to tretinoin for anti-aging skin treatments, offering similar collagen production benefits without increased skin irritation.

This study identified ten compounds from Eclipta prostrata, with some displaying potent inhibitory effects against α-glucosidase and acetylcholinesterase enzymes.

In this study, all stereoisomers of cyoctol were synthesized and tested, revealing that contrary to initial patent claims, cyoctol does not function as an anti-androgen.

This review article discusses the potential benefits of phytochemicals in hair care, highlighting their ability to improve scalp health, reduce dandruff, and promote hair growth, while emphasizing their safety and minimal side effects compared to conventional therapies.

This study found that an ethanolic extract from the microalga Tetrathelmis tetrathele exhibited anti-inflammatory effects, promoted the proliferation of certain skin and hair cells, and inhibited 5α-reductase activity, suggesting its potential as a therapeutic agent for preventing alopecia and enhancing scalp health.

This study identified various phytochemicals and compounds in Eclipta prostrata leaves using qualitative tests, FTIR, and GC-MS analysis, highlighting the presence of phytol and squalene among others.

This study examined the stability of two 5α-reductase inhibitors in Tectona grandis extracts, finding that they are more stable in acidic environments and degrade rapidly under heat and light unless protected, suggesting the need for careful storage when developing anti-hair loss medications.

Minoxidil activation by hair enzymes predicts treatment success for female hair loss.

This review evaluates the anti-aging properties of TSG from He shou wu, finding it may protect against age-related diseases through multiple mechanisms, though further research is needed for clinical application.

Certain enzymes react strongly with some hormones in rat skin during hair growth, mainly in sebaceous glands and hair sheaths.

This study isolated highly pure oleanolic and maslinic acids from olive milling residues, exploring their chemical reactions, including the formation of finasteride precursors.

This study synthesized and evaluated hydroxycinnamate derivatives for their ability to inhibit human SRD5A1, finding that three compounds showed significant inhibitory activity and low cytotoxicity. Compound 10a notably reduced SRD5A1 protein expression in cells, suggesting potential for nonsteroidal treatment of androgen-related conditions.

Fermentation of Finasteride with Ocimum sanctum L. creates new metabolite that inhibits tyrosinase.

This study identified key natural compounds such as polyphenols and flavonoids in tongue fern and established optimal extraction conditions using methanol.

This review summarized and classified 32 approved synthetic and natural-identical antioxidants, examining their regulatory status, safety, pharmacological properties, and effectiveness on human health, aiming to clarify their antioxidant actions and encourage further research in the field.

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.
