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.

This study found that procyanidin B-3, a compound isolated from barley extract, may promote hair growth by enhancing hair epithelial cell growth and counteracting TGF-β1's growth-inhibiting effects in vitro and in vivo.

This study developed a fully automated HPLC method for accurately quantifying finasteride in human plasma, achieving a detection limit of 1 ng/ml with validated application in pharmacokinetic studies.

This study reported that sunscreen with SPF50+ provides a high level of DNA protection against UV-induced damage in a reconstituted human epidermis model, comparable to that in skin explants.

This article reviews the impact of UV radiation and visible light on human hair structure and summarizes protective strategies, reporting no new clinical results.

New method measures minoxidil concentration faster, more accurately, and automatically.

This study identified previously unknown phase I and phase II metabolites of finasteride in human bile and urine using a specialized bile collection technique and advanced mass spectrometry analysis.

This study developed a high performance capillary electrophoresis method, validated for both legal and illicit minoxidil-based products, to confirm minoxidil's presence alongside known impurities.

This study validated a highly selective and fast LC–MS/MS method for accurately measuring levels of tadalafil and finasteride in human plasma, adhering to international bioanalytical guidelines.

This article discusses fluconazole's pharmacological and physicochemical properties and methods for its analysis, but reports no new clinical results.

This study optimized and validated a dissolution test method for immediate-release finasteride capsules, highlighting the need for an official standard due to variability in commercial products.

Researchers created a reliable method to measure dexpanthenol and resorcinol in hair products.

This study reports that two novel chromatographic methods demonstrated high sensitivity and selectivity for determining aminexil, niacinamide, and pyridoxine HCl in a laboratory-prepared mixture and hair tonic preparation.

This study concluded that two different pharmaceutical formulations of finasteride were bioequivalent in terms of rate and extent of absorption based on pharmacokinetic evaluations in a randomized crossover study with 38 volunteers.

This study investigated the photoprotective properties of Brazilian pepper tree extract against UV-induced damage in skin cells, reporting that it enhanced expression of genes relevant to skin health and showed superior activity compared to standard antioxidants.

In this study, researchers identified an elite germplasm of the medicinal plant Eclipta alba, known for its liver disease benefits, with higher growth, yield, and wedelolactone content, suitable for large-scale cultivation to reduce strain on wild populations.

This study concluded that Trilayer Dissolving Microneedles show promise in enhancing Minoxidil delivery for treating alopecia areata by improving its bioavailability and reducing side effects.

This study reviewed the current analytical techniques for estimating finasteride, a drug used for treating benign prostatic hyperplasia, acute urine retention, and male pattern hair loss.

This study introduces three spectrophotometric techniques for accurately determining finasteride and tadalafil in their combined pharmaceutical form, demonstrating their sustainability, sensitivity, and suitability for quality assurance, alongside a dissolution study following FDA guidelines.

This study identified two potent 5α-reductase inhibitors from Tectona grandis leaves, and suggests that ethanol is a preferable solvent for extracting these compounds, which are potential ingredients for hair loss treatments.

This study investigated the use of spironolactone in patients with estrogen-dependent cancers, aiming to determine if it is linked to increased cancer recurrence risk, but results are not reported.

This review discusses the protective and stress-buffering roles of melatonin in skin functions and structures but does not present new clinical findings.

This study found that human skin expresses proenkephalin, whose expression is upregulated by environmental stress and varies in pathological conditions, increasing in psoriasis and decreasing in melanocytic tumors.

This study found that the water extract of Eclipta prostrata L. may protect skin cells against UVB-induced damage, likely due to its antioxidant properties and absorption of UVA and UVB radiation.

This study found that both everyday physical and environmental stresses, as well as chemical treatments, contributed to hair damage, with cuticle layers being more noticeably affected.

This study developed an efficient method for converting polymeric procyanidins into high-purity oligomeric procyanidins using a semisynthetic approach combined with separation techniques.

This study found that non-ionic silicone emulsion best protected hair color from UV-induced fading, outperforming honeysuckle extract and benzophenone-3, with significant effects in both dyed and virgin hair.

This study observed that a five-week topical treatment with cold-pressed Rosa canina seed oil significantly reduced mean wrinkle scores and UV-induced spots in volunteers, suggesting potential anti-aging and photoprotective benefits attributed to its high carotenoid content.

This review highlights that nanoemulsions, especially those with droplet sizes under 200 nm, show promise in pharmaceuticals and cosmetics by improving drug stability, bioavailability, and reducing side effects, with potential applications in CNS diseases, cancer treatments, and skincare products.

This study suggests that UVA-responsive nanocapsules may provide an effective method for skin antisepsis by releasing ethanol and reducing microorganisms within hair follicles on ex vivo porcine ear skin.
