In this study, hair tonic formulations containing moringa leaf extract and honey were tested for stability and found to remain stable and non-irritating after storage, meeting specific quality standards.

This study found that while the reproducibility of hair cortisol measurements in captive chimpanzees was high, the fineness of homogenized hair, sample weight, and extraction time influenced absolute cortisol concentrations.

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 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 rice bran phytochemical-based cosmetic products have high antioxidant capacity, maintain stability at moderate temperatures, and are free from heavy metal and microbial contamination.

In this study, a hair tonic containing fragrant pandan leaf extract and virgin coconut oil was formulated and evaluated, with most variations demonstrating physical stability except for one formulation, which showed instability in the specific gravity test.

This study found that a 2% minoxidil cream for androgenous alopecia maintained optimal rheological properties for consistent application and long-term stability.

This study found that microemulsion and microemulsion-based hydrogels may offer a more effective and sustained topical delivery method for minoxidil compared to conventional solutions for hair loss treatment.

This study developed and evaluated a polyherbal solid shampoo bar using natural ingredients like Amla, Soapnut, Hibiscus, and Aloe vera, and found it to be an effective, safe, and sustainable alternative to conventional hair care products, with good cleansing and lathering properties.

This study found that betasitosterol-loaded nanostructured lipid carriers, when added to butter, improved its nutritional profile and antioxidant properties, maintaining stability over a three-month storage period.

This study discusses ethosomes, which are lipid-based vesicular carriers that improve drug penetration into the skin due to their high ethanol content, highlighting their benefits in drug delivery despite stability issues like phospholipid oxidation and vesicle fusion during storage.

This study concluded that a hair-nourishing formulation combining virgin coconut oil and 4% chilli oil significantly enhanced hair growth in white rats over a 21-day period, while also exhibiting good physical stability under varying storage conditions.

This study found that the gelatinous minoxidil 1% shampoo demonstrated thixotropic properties and mechanical stability, suggesting predictable long-term consistency and effective distribution on the scalp.

In this study, the developed polyherbal shampoo with Hibiscus rosa-sinensis exhibited good stability and cleansing properties, suggesting it may be an effective natural alternative to synthetic anti-hair fall products.

This study found that adding microcapsulated pumpkin seed protein hydrolysate to aloe vera drinks improved antioxidant activity, taste, and shelf life, with chitosan-alginate microcapsules effectively inhibiting microbial growth during 30 days of refrigerated storage.

This study developed a stable, cosmetically appealing formulation for the topical delivery of the peptide FOL-005, enhancing skin permeation and maintaining stability by keeping the peptide solid and in a water-free environment with particle sizes under 10 µm.
