This study demonstrated that Gelfoam® histoculture supports extensive growth of both hair shafts and sensory nerves from isolated mouse whisker follicles over prolonged periods.

This research found that translucent keratin films absorbed more dye than opaque films, suggesting they may serve as better screening substrates for evaluating hair dye effectiveness.

This study found that camel hair from Afif has suitable physical and chemical properties for textile production and its characteristics can be enhanced with chemical additives like acetic acid.

The hydrogel helps heal diabetic wounds by combining antibacterial, antioxidant, and immune-boosting effects.

This study found that phenoxyethanol is the most common contact allergen in over-the-counter hair loss products, but its role in the development or exacerbation of frontal fibrosing alopecia remains unclear.

In this study, researchers developed injectable micropore-forming hydrogels that enhance tissue adhesion strength and promote wound healing by allowing better cell infiltration and inducing hair follicle regeneration in skin incision wound models.

In this study, adding conditioning agents PA1, PA2, and PA3 to light blonde oxidative hair dyes improved combability and protein retention of light brown hair without affecting tensile strength, though PA1 and PA2 offered enhanced thermal protection.

This research demonstrated that transforming pomelo peel into expanded sponges and carbonized aerogels can accelerate hemostasis and enhance healing in diabetic wounds while eradicating bacterial biofilms, offering an eco-friendly solution for wound care from agricultural waste.

This study found that Transcutol P significantly enhanced the skin penetration of Finasteride in vitro, while cationic and anionic surfactants did not show such effects.

Adding human hair to cement can make it tougher and better insulated but also more porous.

This infographic compares the safety profiles of SH‑1, a cosmetic ingredient, which showed no systemic absorption, and PP405, an investigational drug with dose-dependent systemic uptake and potential threshold breaches, highlighting differences in safety between cosmetic and investigational substances according to this report.

This study found that rubbing significantly increased skin permeation of caffeine but not rhododendrol, with the direction of rubbing playing a crucial role in caffeine's enhancement.

This study focused on developing agarose/fucoidan hydrogels for the encapsulation of pancreatic cells, reporting that these materials supported cell viability and self-organization into pseudo-islets over 7 days, highlighting potential for diabetes treatment applications.

In this study, the researchers reported that while both propylene glycol and sodium lauryl sulfate enhanced finasteride's skin deposition, ethanol was the only effective enhancer of finasteride's permeation through the skin.

This review discusses the potential of lecithin organogels for improving topical drug delivery and presents no new experimental results; the authors highlight their stability and low skin irritancy as advantages.

In this study, incorporating a novel amino acid compound into a hair-straightening formulation improved humidity-resistant straightening and enhanced the surface and mechanical properties of hair fibers, including increased bending stiffness, reduced friction, and better shape retention under high temperature and humidity conditions.

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

In this study, carboxymethylalanyl disulfide keratin was shown to effectively prevent hair damage during repeated bleaching and permanent waving treatments.

This study developed analytical methods to better understand hair treatment with cosmetic formulations, revealing that active agents primarily adsorb on the hair surface during short washes.

This study found that tea-seed saponin modified silicone polymer quaternary ammonium salt significantly improves hair conditioning performance in both dry and wet states when used in shampoo formulations.

This study found that the uptake of molecules by hair is influenced by both hydrophobic and ionic charge interactions, with binding affinity decreasing as pH approaches the solute's dissociation constant.

In this study, researchers developed a method called the Stiffness-Angle Law and found that hair treated with caffeine-infused shampoo showed a 13.2% increase in stiffness, as measured by their novel evaluation technique.

This study demonstrated that PEGDA hydrogel microwells successfully supported cell survival and proliferation while mimicking hair follicle architecture in vitro, suggesting a potential tool for hair follicle engineering.

This study found that the polyherbal gel formulations F4 and F6 demonstrated superior in vitro performance in hair care, showing promise as cosmeceutical candidates, although further in vivo and clinical studies are necessary to confirm their efficacy and safety.

This study found that increasing a drug's lipophilicity and adding ethanol to the donor phase can enhance its delivery to the hair follicle, although the precise transport mechanism remains unclear.

In this study, a method using riboflavin phosphate, citric acid, and polyols successfully optimized protein cross-linking in hair of all colors through visible light-mediated photo-cross-linking, improving the mechanical properties and hair-setting effects without the influence of hair color.

This study observed that hair cuticles experience greater water-induced plasticization than hair cortex, affecting the torsional rigidity of hair fibers, which may help predict hair setting behavior.

This study aimed to develop a dermocosmetic exfoliating formulation using babassu fibers for androgenetic alopecia treatment, but found that although the formulation met sensory standards, it was unstable in sunlight and heat, suggesting a need for optimization before commercialization.

This study described the development and evaluation of a finasteride nanogel for treating androgenetic alopecia, reporting higher cumulative drug release and enhanced spreadability compared to a plain gel, suggesting potential as a treatment option.

This study explored microemulsion formulations for delivering finasteride through the skin, finding that higher water concentrations increased permeation, which may inform optimal transdermal delivery for treating androgenetic alopecia.
