Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.

In this study, researchers found that ligand homodimerization controls the receptor binding specificity of the FGF9 subfamily, preventing off-target activation of FGFR "b" isoforms.

This review discusses the role of acyl-CoA binding protein (ACBP) in the epidermal barrier, noting that its disruption in mice is linked to skin and fur abnormalities; it reports no new clinical results.

This study found that the acyl-CoA binding protein is essential for the production of very long chain free fatty acids in the stratum corneum and maintaining normal epidermal barrier function in mice.

This study found that the moisture sorption and desorption process can differentiate between cosmetic treatments of hair and provide insights into hair fibre structure changes, with bleaching causing greater symmetry breaking than perming.

This study found that individuals who perceive their hair health as poor tend to have higher levels of metals on their hair, emphasizing the impact of environmental metal exposure.

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.

This study found that commercially available dyes penetrate up to 1.2 mm into human skin, with Indocyanine Green binding to cell proteins and showing a shift in absorption peak.

This model study describes how interactions between hair keratin and various materials alter hair's physical and mechanical properties by affecting noncovalent bonds.

This study found that the binding and release of BMP-2 from kerateine biomaterials are significantly influenced by pH and salt concentration, highlighting the potential for developing improved bone repair systems.

This article reviews the classification and characteristics of water soluble vitamins, focusing on their varying solubility and functions, and reports no new experimental findings.

The study found that the Marangoni effect causes the uneven wetting of surfactant-coated hair due to the surfactant moving into the water.

This study found that codeine incorporation in guinea pig hair varied with pigmentation and was highest in black hair, suggesting the role of eumelanins in drug binding.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This study suggests that elevated copper levels in domestic tapwater, exacerbated by its aggressive properties, likely contribute to green hair by damaging the cuticle and increasing copper uptake.

This study evaluated formulations of a cream containing turmeric and ginger extracts for inhibiting underarm hair growth, finding that the formulation with 15% stearic acid and 3% triethanolamine had the most optimal physical characteristics and potential for cosmetic development.

This study demonstrates that keratin K2 is crucial for proper keratinocyte structure and function in specific mouse skin areas, and its deficiency leads to cellular aggregates and skin abnormalities.

This study explored the potential of human hair keratin as a filtration material, finding that it may effectively absorb the pollutants diclofenac and perfluorobutanesulfonate. The researchers reported significant binding affinities through molecular simulations, supporting further investigation into keratin's use for water purification.

This study investigated the ability of a human hair keratin dimer to absorb the pollutants diclofenac and perfluorobutane sulfonate, finding high binding affinities that suggest potential for hair-derived materials in water filtration technologies.

This study found that water-soluble beehive extract exhibited anxiolytic, antidepressant, and anti-inflammatory effects in animal models.

In this review, the authors discuss recent advancements in underwater adhesion technologies, specifically highlighting mussel-inspired catechol-based adhesives, which offer strong underwater bonding through various interfacial interactions and the influence of dopamine-modified polymeric tissue adhesives.

This study found that a postbiotic derived from hawthorn and probiotics can alleviate loperamide-induced constipation in aged mice by regulating several physiological processes, including intestinal water and sodium metabolism, maintaining gut flora and barrier, reducing inflammation, and enhancing short-chain fatty acid metabolism.

In this in-vitro study, researchers found that shampoo-induced coacervates structurally resemble cationic polymers and contain anionic surfactants that may stimulate the scalp upon exposure to water.

This study suggests that glycosaminoglycans, like hyaluronic acid obtained biotechnologically, are safe for topical cosmetic use, enhancing skin and hair conditions by supporting cell renewal, stimulating hair growth, and aiding in the treatment of scalp issues such as seborrhea and androgenetic alopecia.

This study introduces a novel pro-drug formulation of all-trans retinoic acid that reduces skin inflammation and achieves sustained drug release over several days compared to traditional methods.

This study used nanoscale secondary ion mass spectrometry to locate where calcium and copper are concentrated in colored hair, finding these metals particularly in the cuticle's sulfur-rich regions.

This study found that low-molecular-weight hyaluronate significantly improved the mechanical strength and elastic modulus of overbleached hair by enhancing hydrogen bond networks within keratin.

This study reported that a novel bilayer wound dressing made from PLCL nanofibers and keratin hydrogel, loaded with FGF-2, promoted skin healing and showed potential for use in skin tissue engineering.

This study found that, despite the unchanged total level of 18-MEA, deletion of the Sox21 gene disrupts its attachment to the hair cuticle, increases cholesterol sulphate levels, and differentially affects ceramide composition.

This review highlights how cyclodextrin-polysaccharide hybrids can advance drug delivery and environmental cleanup by improving the solubility and stability of hydrophobic molecules, serving as promising platforms for biomedical applications and efficient sorbents for wastewater treatment.
