This study found that a bioactive borosilicate glass containing Sr and Cu ions exhibited promising mechanical strength, biocompatibility, and antibacterial activity, particularly the CuSr-1 wt.% composition, suggesting potential for use in orthopedic implants and bone tissue engineering.

This study found that inhibiting neurosteroidogenesis affected GABA A receptor-mediated synaptic inhibition in immature rats but not in adults, suggesting age-dependent modulation of synaptic strength in the spinal dorsal horn.

This study found that keratin-based particles were able to recover and enhance the mechanical properties and thermal stability of virgin and overbleached Asian hair, improving its strength and smoothness by around 40%, and demonstrated safety in human skin keratinocytes.

This study found that pregnane derivatives with higher lipophilicity, like compound 9d, had stronger androgen receptor binding and greater antiandrogenic effects in rats, correlating relative binding affinity with log P values.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

In this research, Holstein cows immunized with human hair keratin produced antibodies in both colostrum and regular milk that specifically bind to hair keratin, enhancing hair tensile strength without affecting skin keratin.

In this study, a new leave-on hair treatment with Dynagen and zinc salts significantly increased hair growth rate, fibre diameter, and follicle strength in healthy women.

This study reviewed existing literature on mesotherapy as a treatment for androgenetic alopecia, finding that it may improve hair density and thickness with generally mild side effects, but emphasized variability in study designs limits the strength of these conclusions.

In this review paper, the authors explored the composition and role of lipids in human hair, highlighting their importance for hair texture, moisture retention, and tensile strength, while noting that the understanding of hair lipids' functions remains controversial and requires further research.

This study found that in models of diabetic wound healing, extracts from the flavonoid and tannin fractions of Ficus racemosa leaves improved wound closure time, increased breaking strength of incision wounds, and exhibited hypoglycemic activity.

This study found that while yak belly hair is chemically similar to human hair, its higher porosity and lower mechanical strength limit its usefulness as a substitute in hair dye development.

This systematic review reported that probiotics, prebiotics, synbiotics, postbiotics, and dietary supplements may improve hair density and reduce dandruff severity in individuals with scalp disorders, potentially by modifying inflammation, oxidative stress, and microbiota composition; however, variability across studies limits the strength of these conclusions.

This study investigated how vitamin A deficiency, certain diseases, and pregnancy affect cattle coat hair structure, finding notable keratin fibril interference under vitamin A deficiency and structural modifications in chronic renal failure, while pregnant cows exhibited superior hair tensile strength compared to non-pregnant ones.

This study reported that Tomorrowlabs HIF strengthening factor [HSF] hair restoration technology significantly improved hair thickness, density, shine, and elasticity, while reducing hair loss by an average of 66.8% and enhancing hair growth by up to 32.5% in subjects with androgenic alopecia over nine months.

Keratin-associated proteins are crucial for hair strength and structure.

This study suggests that the C-terminal of AHF is crucial for its binding to keratin bundles and modulating the keratin meshwork in hair follicles.

Qu-shi-yu-fa Decoction may help treat hair loss by promoting hair growth and strengthening.

This study found that disulfide bonds in keratin increase its strength and toughness, with some loss of α-helical structure under load, highlighting their role in trichocyte α-keratin's mechanical properties.

This meta-analysis reported no significant improvement in muscle strength or mobility with glucocorticoid treatment for progressive muscular dystrophy but observed an increase in adverse effects like acne and emotional irritability.

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.

This study demonstrated that HOXC13 directly influences hair keratin gene expression by binding to specific DNA motifs, suggesting its role in early hair follicle differentiation.

This study found that Golvatinib, Gliquidone, and Dihydroergotamine may inhibit the binding of SARS-CoV-2's Nsp1 protein to the host ribosomal subunit, suggesting potential as treatments against COVID-19 variants.

In this study, nanostructured lipid carriers for hair split-end repair showed similar efficacy regardless of charge, with negatively charged carriers exhibiting better stability over six months compared to positively charged ones.

This article reviews multiple books on topics including tissue augmentation and pigmentary system physiology, with no new clinical findings reported.

This study demonstrated that while the proposed placebo microneedle stamp design was partially successful in blinding participants with low skin sensitivity, further development of suitable placebo controls is needed.

This study found that incorporating CTA2-BADG, a modified hair-rebonding compound, into damaged hair significantly improved surface morphology and tensile strength by using charge-conversion chemistry to enhance penetration into the hair shaft.

Repetin is a protein involved in skin and hair development, binding calcium and compensating for other proteins when needed.

This study found that overexpression of betacellulin in transgenic mice delayed hair follicle morphogenesis and cycling, increased keratinocyte proliferation, and enhanced wound angiogenesis without affecting wound healing strength.

This study found that bovine lactoferrin promotes hair growth in mice by enhancing dermal papilla cell proliferation through the Erk/Akt and Wnt signaling pathways.

In laboratory and artificial skin model experiments, this study found that plant-derived PDRN from Korean ginseng effectively promoted skin cell regeneration and strengthened the skin barrier, suggesting a sustainable alternative to animal-derived PDRN.
