This study developed a precise and simple HPLC method for estimating tamsulosin and finasteride simultaneously in pharmaceutical forms, demonstrating good precision and potential usefulness for combined dosage analysis.

This study found that a herbal gel containing fenugreek seed extract significantly promoted hair growth on mice after 30 days of topical application.

This study evaluated various herbal blends of powdered leaves, including Henna and Indigo, for their coloring and sensitivity reactions, finding Henna and Indigo to be effective natural colorants for achieving a reddish-brown hair color with better retention than marketed herbal hair dyes.

In this study, bleaching and perming were found to significantly reduce opiate concentrations in both spiked and naturally opiate-positive human hair samples.

This review discusses the role of reactive oxygen species in regulating oscillating apoplastic pH gradients and growth in plant root hairs and pollen tubes, reporting no new experimental results.

This study developed and validated a micellar electrokinetic chromatography method to determine finasteride stability, finding that the drug degrades under acidic, basic, and oxidative stress conditions.

In this study, researchers developed a reliable HPLC method to simultaneously estimate Finasteride and Tadalafil in marketed formulations, showing precise, linear results with confirmed degradation susceptibility under certain stress conditions.

This study found that dexamethasone-loaded Eudragit® L 100 nanoparticles displayed controlled drug release depending on pH levels, with minimal toxicity to human fibroblasts.

This study found that the pH dependency of rat steroid 5α-reductase type II isozyme significantly affects its kinetic properties, including Vmax and Km, suggesting past discrepancies in literature may arise from these pH variances during assays.

This study found that bleached hair showed optimal protein structural integrity and tensile strength at pH 5, with significant changes in cross-linking, water content, and diameter at more alkaline or acidic levels.

This review outlines the current understanding of how pH contributes to root hair development and reports no new experimental findings.

This study established a new reverse-phase high-performance liquid chromatography method to accurately and precisely quantify silodosin and dutasteride in mixtures, meeting International Council of Harmonization validation criteria for stability, sensitivity, and recovery.

In this study, researchers found that finasteride undergoes second-order alkaline degradation kinetics and that its degraded form negatively impacts cell proliferation, highlighting the need for careful handling in pharmaceutical manufacturing and storage.

In this study, tresses treated with pH 1.0 acid straightener showed better straightening but more damage to hair properties compared to those treated with pH 2.0.

This study developed a novel LC-ESI-MS/MS method to quantify Minoxidil in pharmaceutical forms, finding it precise, accurate, and robust. It withstands excipient and degradant interference, although Minoxidil degrades under some stress conditions but remains stable thermally.

This study found that a green tea extract gel was stable across various temperatures, did not cause eye irritation, and significantly increased eyelash growth compared to a placebo after two months of use in human volunteers.

This study found that the pH-sensitive hydrogel HECHA13, containing isoliquiritigenin, effectively inhibited the growth of Propionibacterium acnes and showed promise for transdermal delivery in acne treatment.

This study reported that a novel liposomal formulation, SP-bFGF-SF-LIP, enhanced bFGF stability and skin permeability, significantly improving hair follicle recovery and wound healing in a mouse model.

This study established a stable formulation for caffeine nanocrystals in specific solvent mixtures, which could be used to test their potential for enhanced hair follicle targeting and penetration.

This study found that a single application of 'Lye' or 'No-Lye' chemical straighteners significantly reduced drug concentrations in hair samples from both drug-fortified standards and authentic drug users.

The researchers reported that a polyherbal hair dye using Phyllanthus reticulatus fruit provided effective color, stability, and scalp compatibility without irritation, positioning it as a safe and eco-friendly alternative to synthetic dyes.

This study found that combining shikimic acid with Prunus mume fruit extract significantly reduces type I 5α-reductase levels in testosterone-stressed skin sebocytes, surpassing the effects of shikimic acid or standard acne treatments alone, and shows promise for stable, non-irritating acne remedies in cosmetic formulations.

This study found that Soxhlet extraction is more effective at removing the toxin mimosine from Leucaena leucocephala, and mimosine shows promise as a biodiesel additive due to its antioxidative properties.

This study focused on designing a niosome formulation that encapsulates pumpkin seed oil for topical use, achieving high entrapment efficiency and stability over three months.

In this study, researchers developed a pH-sensitive dendritic polyglycerol nanogel to measure pH inside hair follicles using an ex vivo porcine ear model, finding that the pH increases from 6.5 at the skin surface to 7.4 in deeper follicle areas, without observed toxicity.

The researchers reported that glucuronides stored as dried blood spots under ambient conditions exhibited stability equivalent to liquid samples stored at -80°C.

This study describes a method to extract and characterize keratin particles from human hair, finding they can encapsulate the anticancer drug Paclitaxel with significant efficiency, releasing it in a pH-dependent manner potentially beneficial for targeted cancer treatment.

This study found that purified wood vinegar may promote hair growth in mice without toxicity, suggesting its potential use in treating baldness or alopecia.

This study found that the newly developed microarray patches for intradermal delivery of finasteride showed high drug content and significantly improved skin deposition compared to existing methods.

This review suggests that standardized herbal shampoos may offer a safe and sustainable alternative to synthetic products due to their natural saponins and multifunctional benefits, though challenges in consistency and shelf-life persist.
