This study describes a new method for extracting red mordant dyes from wool fibers using ethylene diamine tetraacetic acid and N,N-dimethyl formamide, preserving the fibers for further examination.

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 study introduced a new method for extracting red mordant dyes from wool fibers that preserved the fibers for further analysis and allowed for spectrophotometric examination of the dyes' absorption curves.

Some oils can penetrate hair and reduce the stickiness between fibers, but mineral oil cannot.

The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.

This review examines mechanical and chemical causes of hair fiber adhesion failure and fracture patterns in the cell membrane complex, but presents no new experimental results.

Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.

This study found that seasonal changes significantly affected hair follicle activity and fibre growth in Merghoz goats, with variations seen in feed intake and growth patterns across different seasons.

This study found that polyquaternium-68 at pH 9 achieved the greatest hair deposition, while polyquaternium-44 demonstrated the best wash resistance at pH 6.

In this study, a bioengineered construct using a biodegradable polycaprolactone mat cocultured with human keratinocyte and rabbit dermal fibroblast cells demonstrated potential as a tissue-engineered skin substitute, showing good cell adhesion and growth.

This study found that the extent of reducing agents' effects on hair fibers was linked to the electrode potential of the reagents used.

This study found that monounsaturated oils like olive oil penetrate hair fibers effectively, whereas polyunsaturated oils typically do not penetrate beyond the cuticle.

This study documented that fiber hair implants effectively restored hair in over 85% of patients with permanent alopecia, with only mild and rare complications reported.

This study found that oil from CG17 garden cress seeds had higher amounts of β-carotenoids, tocopherols, and vitamins compared to other genotypes, with varying physiochemical properties across all seeds.

Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.

The authors reported that fiber hair implants provided excellent results in over 85% of patients with permanent alopecia, with mild complications and a yearly fiber failure rate below 20%.

In this study, variation in the KRTAP15-1 gene in goats was linked to changes in cashmere fibre diameter, with specific variants showing dominant or recessive effects.

This study characterized the stress-strain properties of the human scalp and found that its stiffness increases significantly with load, providing valuable insights for planning scalp surgery procedures.

This study found that the cuticle layer of hair contributes approximately 60% to bending stress, highlighting its significant role in the mechanical properties of hair stiffness.

In this study, low-level laser therapy significantly improved the mechanical strength of bone at tooth extraction sites in rats, while neither platelet-rich plasma alone nor combined with laser affected mechanical strength or calcium content.

This source highlights the utility of cationic polymers in haircare products for protecting against hair damage from chemical treatments and grooming, and describes how microfluorometry can measure polymer deposition and penetration on hair fibers.

Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.

This study observed that adults with thinning hair who ingested a patented botanical-based supplement experienced significant increases in hair shaft diameter and reductions in hair breakage over 180 days, suggesting improved hair strength and length across various demographic groups.

This study suggests that ethylene and lignoceric acid (C24:0) may promote cotton fiber and Arabidopsis root hair growth by activating the pectin biosynthesis network.

This study observed that keratose, derived from human hair, integrated well in mouse tissue and remodeled with collagen, suggesting potential as a non-toxic biomaterial for regenerative applications.

This review discusses the shedding phase of the hair cycle, known as exogen, and reports no new findings while analyzing related processes like club fiber formation and release.

In this study, bleaching and perming were found to significantly reduce opiate concentrations in both spiked and naturally opiate-positive human hair samples.

This study found that xylanase and pectinase enzymes clean wool and specialty hair fibers as effectively as soap, without causing physical damage, whereas resinase was not effective.

Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.

This study reports that biomass activated carbon fibers derived from metaplexis japonica seed hair effectively adsorb methylene blue dye, demonstrating high capacity and rapid adsorption performance.
