This study found that hair care formulations containing argan oil were stable and demonstrated better spreadability and texture profiles compared to those without argan oil.

This study demonstrated that human hair can be coated with Fe3O4 nanoparticles, allowing it to be oriented and moved by a magnetic field, which may enhance drug delivery and hair care applications.

This study found that a hair tonic formulated with 0.3% cocoa bean extract demonstrated the best physical stability and effectively promoted hair growth in mice, with results comparable to a positive control when used twice daily for two weeks.

In this study, researchers evaluated the stability and color changes of compounded minoxidil formulations used for alopecia, finding that while the formulations remained chemically and microbiologically stable for up to 380 days, significant color changes were observed, which likely do not affect the product's effectiveness.

This review discusses various hair loss treatments, such as stem cell therapy, laser therapies, and mesotherapy, emphasizing their potential and limitations while highlighting the need for further research to address genetic factors in hair loss.

This study found that a missense mutation in the FGF5 gene is associated with hair-length differences among various dog breeds.

This study found that a lotion containing 1% xanthan gum had the best physical stability for candlenut extract hair-restoring lotion, with no significant change in flavonoid content after storage.

This study found that a hair tonic containing 40% broccoli stalks extract was more effective in promoting hair growth in male white rats compared to lower concentrations, while also maintaining stable physical characteristics and safety during testing.

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.

In this study, a daily low-dose regimen of oral minoxidil and finasteride over 12 months led to significant hair density improvements in over 92% of adult men with androgenetic alopecia, including those with advanced stages, though inter-rater reliability in photo assessments was modest.

The authors conclude that optimizing hair shaft production and appearance may best be achieved by integrating biological, chemical, and physical intervention strategies.

This review highlights the potential of integrating non-surgical hair restoration treatments, such as nutraceuticals and PRP injections, into plastic surgery practices, especially for female patients, but reports no new clinical findings.

This research reports that KCV and its palmitoylated derivatives show strong effectiveness in strengthening hair proteins, indicating their potential for use in advanced hair care products.

This study found that a bio-based repair solution containing hydrolysed wool keratin, serine, and transglutaminase improved the physical and chemical properties of damaged hair, increasing its strength, flexibility, and thermal stability while offering long-lasting protection against chemical damage.

In this study, molecular dynamics simulations indicated that the Glu413Lys mutation in human hair keratin significantly affects the stability of coiled coil structures, whereas Glu413Asp showed no impact on stability.

This study found that the transcription factor Gata6 plays a crucial role in adult mouse hair follicle regeneration by promoting the renewal and preventing DNA damage of rapidly proliferating progenitor cells.

This study describes how shotgun proteomics can identify over 300 proteins in hair shafts, potentially allowing for the diagnosis of diseases through noninvasive human proteome sampling.

Finasteride remains stable for two years with proper storage.

This study found that excess vitamin A induced stable glandular morphogenesis and mucous metaplasia in embryonic mouse vibrissa follicles, even after switching to standard medium.

In this study, a hair tonic formulated from a 10% water fraction of Angiopteris evecta extract was reported to be stable and promote hair growth in rabbits, showing equal or greater efficacy compared to a synthetic minoxidil control, while being safe and non-irritating.

This study investigated the effect of peracetic acid treatment on hair fiber structure and found that disulfide bond oxidation altered thermal properties while preserving the α-crystal structure, suggesting different stabilizing interactions in hair fibers.

This review summarizes current research on natural hair dyes, reporting that plant-based formulations can safely provide viable colors on gray hair with minimal irritation compared to synthetic options but face challenges in color range and consistency.

This study found that modern styling cosmetics can significantly alter hair structure through changes in interfacial chemistry and cohesion, particularly when applied to already damaged hair.

In this study, a copolymer made from Tung oil and Tung free fatty acids demonstrated improved mechanical and thermal properties for hair repair, with enhanced resistance and flexibility observed in treated bleached hair, suggesting its potential as a sustainable biopolymer for cosmetic applications.

In this study, a bleaching protocol was developed to evaluate hair repair products, revealing that K18® and Olaplex® improve hair brightness and lightness, with distinct impacts on hair fiber properties.

This review article describes the ingredients and evaluation tests for formulating a hair serum aimed at improving hair growth and preventing hair loss, highlighting the roles of Citrus sinensis, Nigella sativa, flax seed, and coconut oil in addressing hair and scalp health.

In this study with guinea pigs, a hair tonic containing 0.001% caffeine significantly stimulated hair growth, showing higher effectiveness with an average hair length of 18.294 mm compared to a tonic with 0.005% caffeine concentration, which resulted in an average hair length of 16.610 mm.

In this study, the researchers formulated an herbal shampoo and found it exhibited excellent cleansing properties and foam stability, comparable to commercial shampoos, suggesting it as a safe and cost-effective alternative to marketed formulations.

In this study, researchers found that aloe vera hair tonic preparations containing 10% and 15% extract concentrations significantly enhanced hair growth in rats and remained physically stable across various temperature conditions.

In a study on female Wistar rats, researchers found that a hair tonic containing a 7.5%:2% combination of talok and pare leaf extracts increased hair growth comparable to minoxidil, showing similar efficacy in promoting hair growth without significant statistical difference.
