This letter discusses the potential of green tea extract as a treatment for hirsutism but reports no clinical outcomes.

In this study, researchers found that stabilizing the protein HIF1A in hair follicles promotes glycolysis over oxidative phosphorylation, potentially reducing oxidative stress and supporting hair growth.

This study found that t-flavanone may promote hair growth in people with androgenic alopecia by enhancing hair anchoring strength and upregulating desmoglein expression in hair follicles over 30 weeks.

This study reviews how oxidative stress affects hair follicle development and hair growth, discusses antioxidant-based treatments for hair loss, and evaluates natural antioxidant products that promote hair growth, emphasizing the need for further research due to existing limitations.

This study found that ethosome-loaded minoxidil and tocopherol acetate improved hair regeneration and regulated the microenvironment around hair follicles better than commercial minoxidil in androgenic alopecia model mice, showing promise as a treatment strategy.

In this study, the researchers optimized the extraction conditions for crude polysaccharide from Hibiscus rosa-sinensis leaves, achieving a yield of 9.66% and demonstrated strong antioxidant activities in vitro.

This study found that topical application of TSG from Polygonum multiflorum promoted hair regrowth in depilated mice, potentially through the inhibition of apoptosis-related proteins.

This review discusses key molecular targets in cosmetic research and reports no clinical results; it highlights the role of telomerase, sirtuins, and tyrosinase in anti-aging and depigmentation strategies.

The moisturizer with phytol improved skin texture and reduced fine wrinkles better than the moisturizer without it.

This review emphasizes the potential of repurposing topical L-thyroxine for skin ulcers and telogen effluvium and highlights the need for further exploration of its use in dermatology.

This study found that hydroxysafflor yellow A-rich Carthamus tinctorius extract promoted hair growth and gene expression linked to hair proliferation in both cell cultures and mouse models.

This study suggests that phloroglucinol may enhance anagen signaling and reduce oxidative stress-induced damage in human dermal papilla cells, offering a potential therapy for hair loss.

This article discusses the functions of the enzyme 17beta-HSD10, including its role in steroid metabolism and potential links to Alzheimer's disease, but reports no new experimental findings.

This study demonstrated that several botanical extracts possess antioxidant properties, reducing oxidative stress and lipid oxidation in scalp treatments, with rosemary extract showing potential to improve scalp condition in a 4-week consumer trial.

This study found that the synthetic thyroid hormone receptor modulator KB2115 significantly prolonged the growth phase of human hair follicles in culture without altering mitochondrial activity, suggesting potential as a safer hair loss treatment compared to traditional thyroid hormones.

ROS may affect hair loss related to hormones.

This study found that myo-inositol treatment reduced hirsutism and acne in women with PCOS by improving their metabolic profiles, including lower insulin and testosterone levels.

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 found that individuals with premature hair graying had significantly lower levels of antioxidants compared to controls, but the severity of graying did not significantly correlate with oxidative stress levels.

This review discusses the phytoconstituents and biological properties of T. orientalis and T. occidentalis, but reports no new clinical results.

This study found that administering melatonin for 12 weeks to women with PCOS significantly reduced hirsutism, testosterone, and inflammation markers, while enhancing antioxidant levels compared to a placebo.

In this study, testing Annurca apple extract on human follicle dermal papilla cells indicated its potential to prevent patterned hair loss by reducing oxidative stress and increasing factors involved in hair growth.

This study reported that using piroctone olamine in either a shampoo or leave-on product form significantly increased hair retention and improved scalp condition in women with perceived hair thinning.

In this study with C57BL/6 mice, SHJ extract was associated with increased hair growth and density, suggesting potential use in hair care cosmeceuticals, while also enhancing melanin production in melanoma cells.

In this study, L-threonate was observed to inhibit DHT-induced DKK-1 expression in dermal papilla cells and reverse DHT's inhibitory effects on outer root sheath cell growth, suggesting potential as a treatment for androgen-driven balding.

This study found that the aerial parts (leaves and flowers) of Scorzonera undulata from southwest Tunisia demonstrated higher antioxidant activity and beneficial biological properties compared to its tubers.

This review examines clinical trials on polyphenol-based therapies for dermatological conditions, suggesting potential benefits for anogenital warts, alopecia, and acne, but calls for more rigorous trials.

This review highlights the potential of valorizing citrus by-products, particularly hesperidin from orange peels, as sustainable ingredients in skincare for antiaging, pigmentation, wound healing, and UV damage protection, emphasizing hesperidin's role in a circular economy approach.

In this study, a scalp care solution with 0.5% timosaponin B‐II from Anemarrhena asphodeloides significantly improved hair luster, reduced hair fall, enhanced scalp hydration, and decreased scalp redness over 28 days, suggesting benefits for scalp health and hair loss prevention.

This study found that extracts from Hom Thong banana peels, rich in phenolic compounds, may inhibit melanin production in human and mouse melanoma cells, showing potential as anti-melanogenic agents comparable to standard treatments like arbutin and kojic acid.
