This study evaluated a UV-Vis spectrophotometric method to measure minoxidil in compounded capsules from pharmacies in Pernambuco, Brazil, finding that while the formulations met weight criteria, most deviated significantly from declared minoxidil content, highlighting the need for robust quality control in compounded medicines.

This study measured caffeine content in ethanolic extracts of robusta coffee beans, finding 221.58 mg of caffeine per gram of extract, which aligns with known levels for Coffea canephora.

In this study, researchers prepared and analyzed two varieties of homeopathic medicated hair oil using UV-VIS spectrophotometry. They reported specific absorbance values for each oil type, which were made by mixing mother tinctures of Jaborandi, Embelica officinalis, and Robinia with coconut oil.

This study developed and validated a simple, precise, and cost-effective UV spectrophotometric method for quantifying Minoxidil in bulk and pharmaceutical forms, reporting high accuracy with recovery rates between 99.57% and 100.55%, and a correlation coefficient of 0.9993.

This study developed a reliable HPLC-UV/Vis method to determine aluminum phthalocyanine chloride in skin, supporting its use in skin permeation studies for photodynamic therapy of cutaneous tumors.

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 developed and validated a simple, cost-effective UV–Visible spectrophotometric method for estimating finasteride in pharmaceuticals, demonstrating good linearity, accuracy, precision, and sensitivity according to ICH guidelines, making it suitable for routine quality control.

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

This study demonstrated that visible light lightens blond hair more effectively than ultraviolet light, attacking melanin granules directly, whereas ultraviolet light primarily damages other hair tissues following washing.

This article discusses how the balding scalp's exposure to UV and near-infrared light may accelerate aging, with changes detectable under ultraviolet light; it presents no new clinical findings.

In this study, silver nanoparticles derived from Ziziphus nummularia leaf extract showed enhanced antibacterial, antifungal, antioxidant, and hair growth properties compared to the leaf extract itself.

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

In this study, extracts from Chenopodium quinoa, Glycine max, and Malpighia emarginata demonstrated stability, low toxicity, and effective cleaning potential as surfactants in shampoo formulations, showing performance similar to or better than commercial shampoos in terms of surface and interfacial tension and sebum removal.

Minoxidil reacts to nitrosation 7 times more than phenol, mainly due to its -NH₂ groups, leading to the creation of N-nitrosominoxidil.

This study reported that the calculated and experimental electronic and vibrational properties of minoxidil were in good agreement, providing detailed insights into its molecular structure and thermal behaviors.

This study analyzed how oxidative hair dye leaches from pigmented and nonpigmented hair during wash cycles, finding that melanin influences the dye deposition and leaching processes.

This study developed a new finasteride release system using chitosan-based nanoniosomes, observing that 70% of the drug was released over ten days in vitro, suggesting potential for prostate cancer prevention.

This study found that nickel oxide nanoparticles synthesized using Alternanthera sessilis extract may have potential as antimicrobial, antifungal, and dye-removal agents.

In this study, commercial synthetic braiding hair samples from Kenya were analyzed, revealing that while no Ammonium Thioglycolate was detected, significant formaldehyde contamination was present, with varying concentrations throughout the hair strands, potentially impacting consumer safety.

In this study, researchers found that adding coffee grounds to neutral shampoo, a popular DIY trend, resulted in peak caffeine extraction after seven days, with concentrations surpassing those in commercial products, suggesting educational potential for chemistry classes.

This study developed chemical fingerprints to differentiate Eclipta prostrata and Wedelia calendulacea, two plants often confused and adulterated in the Indian herbal market, identifying distinct chemical profiles that can prevent such adulteration.

This study developed a spectrophotometric method to determine minoxidil in pharmaceuticals, creating a highly sensitive, simple, and cost-effective approach using a synthesized charge transfer complex with a notable absorption peak at 505 nm.

This study reports that hair oil formulations using Arnica montana in castor and mustard oil bases showed effective results in quality and quantitative analysis through UV visible spectrophotometer, FTIR, and HPTLC testing methods.

This study found that Indian and Chinese black hair, with higher melanin content, resist photochemical degradation better than European hair, which has lower melanin levels, when exposed to dry, hot climates.

This study found that sunlight exposure causes significant structural and chemical damage to hair, including cuticle loss, cortex damage, and discoloration, with water playing a major role in discoloration of brown hair.

This review discusses the role of antioxidants in managing oxidative skin damage and reports no new results, emphasizing the need for understanding their mechanisms, limitations, and risks for safe use.

This review suggests that melasma may be a photoaging skin disorder affecting genetically predisposed individuals, which could significantly influence its treatment and prevention strategies.

This review discusses the mechanisms by which sunlight exposure aggravates hair aging and highlights the role of hair pigments in providing photochemical protection, reporting no new results.

This study found that bleaching, dyeing, and UVA/Vis radiation caused significant cuticle damage and protein loss in both Caucasian and Afro-ethnic hair, highlighting the aggressive nature of these treatments.

This review explores the clinical characteristics, risk factors, and treatment challenges of scalp basal cell carcinoma, noting its potential aggressiveness and difficulty in treatment, but reports no new clinical results.
