This study concluded that Polyquaternium-10 conditioner softens the surface of the scale face on hair fibers.

This study found that longer-chain cationic surfactants like BTMC provided superior hair conditioning by reducing combing forces, but did not reverse oxidative hair damage, emphasizing the role of molecular structure in surfactant performance.

The researchers reported that adding specific combinations of hydrolyzed proteins to silicone-free shampoo improved hair conditioning properties by reducing friction and increasing surface adsorption and penetration into hair, compared to protein-free alternatives.

This study discusses the effects of incorporating various amino acids in hair care products, noting improvements in hair surface properties and color retention when integrated with conditioners.

A new method helps understand hair shine and various products improve hair care.

This study found that a conditioner treatment using 18-MEA combined with a specific cationic surfactant effectively restored hydrophobicity and reduced friction on damaged hair surfaces.

This study found that enzymatic phosphorylation of hair keratin increased its capacity to adsorb cationic components like methylene blue and may have practical implications for hair care products.

This study reported that a novel cationic liposome formulation for delivering encapsulated Cas9 protein and sgRNA successfully decreased SRD5α2 mRNA expression by 29.7% in vitro, suggesting a potential alternative treatment option for conditions like prostate cancer and benign prostatic hyperplasia without current drug side effects.

This study found that differently charged micelles influence the acid-base equilibria of cetirizine by altering its ionization constants, indicating potential interactions with biomolecules of various charges under physiological conditions.

This review discusses how polymer-based nanocarriers can enhance drug delivery targeting hair follicles for acne treatment, focusing on factors affecting this delivery method, combination technologies to improve follicle targeting, and recent advancements in polymer nanodrug-delivery systems.

This study found that dimethylpabamidopropyl laurdimonium tosylate, a quaternary ammonium surfactant, adsorbs onto human scalp hair with kinetic and isotherm behaviors fitting specific models, changing hair fiber wettability from hydrophobic to hydrophilic.

This study observed that including cationic minoxidil particles in a shampoo facilitated notable hair growth promotion despite a negative surface charge after rinsing, likely due to ionic interactions with the skin.

This study found that liposomes coated with cationic polymers, chitosan and Eudragit EPO, showed improved physicochemical stability and enhanced skin diffusion of aciclovir and minoxidil compared to uncoated liposomes.

This study suggests that gel containing OSF3 loaded in niosomes offers high transfollicular penetration for topical anti-androgenic alopecia treatment with minimal systemic effect.

Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.

Twisting hair weakens it, but strength can be recovered at low twist levels.

This paper discusses the use of Digital Volumetric Imaging with fluorescent dyes to visualize and compare the interior structures of six different virgin hair types, reporting no new clinical results.

This study found that antisense oligonucleotides can significantly reduce androgen receptor expression in cultured human sebocytes and may offer new therapeutic possibilities for androgen-associated skin diseases.

This review discusses the role of vitamin D metabolism in skin immunity and wound healing but does not present new results, highlighting the need for further research into its therapeutic applications.

This study found that hinokitiol in cationic vesicles promoted hair growth in mice, potentially due to its high substantivity on the skin.

In testosterone-induced AGA mouse models, this study found that a dual-drug-loaded cationic nanoemulsion of minoxidil and finasteride enhanced follicle-associated retention, supporting hair regeneration while reducing systemic absorption and showing good skin compatibility, indicating a promising approach for androgenetic alopecia treatment.
