This chapter reviews formulation principles for creating cosmetic nanoemulsions and applications targeting skin and hair care, but does not present new experimental results.

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

This study found that cetaceans have adapted their fibroblast growth factors to assist in low bone density, hypoxia tolerance, and the development of rigid flippers, reflecting significant evolutionary changes for aquatic life.

In this study, the researchers observed that the transdermal permeation mechanisms of diclofenac salts differ based on counterions, with varying pathways and routes for passive and iontophoretic transport.

This study observed that repeated perm treatments decrease disulfide bonds in hair due to their conversion largely into cysteic acid, affecting the waving efficiency depending on the reduction agent used.

This study found that the FIA-amperometric method for minoxidil quantification in pharmaceutical preparations provided accurate results comparable to the conventional UV technique, indicating no systematic errors.

This study suggests that DHT may have a less potent effect on the prostate compared to testosterone while maintaining safety and similar effects on erythropoiesis and lipids.

This study found that co-applying Curcuma aeruginosa extract or essential oil with minoxidil significantly increased minoxidil's skin penetration in an ex vivo setting, suggesting an improved topical treatment strategy for androgenic alopecia with greater efficacy and the potential for lower minoxidil doses.

This study found that invasomes enhanced the iontophoretic transdermal delivery of finasteride in rabbits, increasing AUC and T1/2 compared to oral suspension.

Niosomes are a promising and effective way to deliver drugs through the skin.

This study found that Flammulina velutipes polysaccharides-derived scaffolds greatly enhanced wound healing and hair follicle regeneration in a rat model, particularly with the FPS/NaOH variant showing the best results.

This study found that dual-frequency ultrasound with microbubble cavitation significantly enhanced minoxidil delivery and hair growth in both lab and animal models compared to single-frequency ultrasound, without damaging the skin in mice.

Created microspheres show potential for safe and effective use in prostate artery embolization.

This study validated the differential stripping technique on hairless rat skin and found that the P-08–016 formulation delivered more finasteride to the epidermis and appendages compared to P-10–008.

This study's molecular dynamics simulations suggest that electrostatic interactions mainly stabilize peptide binding to human hair keratin, with the protein's dielectric constant significantly affecting free energy calculations.

This study found that hair absorbs significant amounts of NaBr from solution, with absorption increasing linearly with solution concentration and additional effects noted with acidic or basic solutions.

This review covers various aspects of hair biology, pigmentation, and development, focusing on genetic and biochemical modulation of hair follicle components but reports no new findings.

This study found that a topical transethosomal system may enhance the skin penetration and deposition of naftifine compared to a marketed cream, potentially overcoming the stratum corneum barrier.

The researchers reported that sterol surfactants with a bulky planar structure effectively solubilized ultraviolet ray absorbers, offering a stable solution more efficiently than other surfactants.

This study developed solid lipid nanoparticles for effective delivery of shRNA-encoding plasmids, showing reduced 5α-reductase levels in DU-145 cells without significant cytotoxicity.

This study found that transethosomal gel loaded with propranolol hydrochloride prolonged drug release and increased peak plasma concentration compared to an oral tablet, suggesting a promising alternative for delivery.

This study demonstrated that the Turing bifurcation, typically a pitchfork bifurcation under zero-flux conditions, becomes transcritical under fixed boundary conditions, highlighting the importance of considering boundary condition variations in morphogenetic analyses.

This study found that CoQ10 formulated in transethosomes showed improved penetration and a better clinical response in treating androgenic alopecia compared to CoQ10 solution.

This study found that administering testosterone to ovariectomized female rats decreased endometrial tight junction complexity and expression of specific proteins, potentially affecting embryo implantation.

This study found that hair follicle-plugging reduced skin permeation of certain model drugs, with effects varying based on EtOH pretreatment and the drug being evaluated.

This study developed an efficient LC-MS bioanalytical method to simultaneously quantify minoxidil sulphate and latanoprost in skin layers, supporting the formulation of topical treatments for androgenic alopecia.

This study suggests that a microemulsion formulation of Minoxidil effectively enhances drug delivery through hair follicles, showing significant follicular response alterations in an alopecia model.

This research found that ethosomes significantly enhanced finasteride delivery into the dermis of human cadaver skin compared to liposomes in an in vitro study.

This study observed that amino acid uptake into wool follicles varies significantly, with cysteine showing the highest uptake rate, suggesting specialized transport systems that may influence wool growth.

This study on feather pattern formation in chicken skin found that inhibiting gap junctional intercellular communication can lead to the emergence of new feather buds in specific spatial patterns, suggesting that GJIC may facilitate Turing-type periodic patterning by propagating inhibitory signals over long distances.
