This study reports that hair damage from bleaching is associated with the oxidative cleavage of fatty acid thioester bonds, detectable by measuring the decrease in mass spectrometry peak at m / z 76.

This study found that thermal hair-straightening devices significantly damaged the cuticle and cortex of virgin Asian and Caucasian hair, with Asian hair experiencing more protein loss than Caucasian hair.

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

This study investigated the penetration of a low-molecular-weight cationic conditioning compound into the hair cortex and suggests it may improve hair's fatigue resistance.

This study discusses the proteomic profile associated with hair damage but does not report new experimental findings.

In this study, researchers found that Asian hair contains more integral lipids than European or African hair, which may protect it better from UV-induced damage.

This chapter reviews the anatomy and structure of hair, discusses hair damage and analyses, and explores methods for processing hair changes, but presents no new research findings.

This study found that cultured dental papilla cells from various mammals can induce hair follicle regeneration and influence tissue formation, with outcomes dependent on donor age, tooth type, and host environment.

This study found that androgen/androgen receptor signaling accelerates premature senescence in dermal papilla cells, highlighting a potential target for treating androgenetic alopecia.

In this study, four male patients with extensively photodamaged scalps showed a 60-90% improvement in dyspigmentation, lentigines, and keratosis after a single treatment with the fractionated 1,927 nm thulium fiber laser, with no adverse events observed.

This study found that fiber implantation for pattern baldness frequently led to complications, including infection and scarring, and poses carcinogenesis risks, leading authorities to discourage its use.

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.

This study found that homocysteine-keratin accumulation in human hair increases towards the tips, linked to copper/iron-catalyzed demethylation of methionine, and may contribute to keratin damage.

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

This study found that hair proteome profiling and genetically variant peptide identification in hairs remained effective after an explosive blast, indicating potential for forensic human identification despite damage.

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

Merino wool fibers change shape with moisture, while human hair shape stays the same.

This study demonstrated that urea significantly accelerates the diffusion of poly(ethylene imine) into bleached human hair by increasing the diffusion coefficient twofold.

This study found that hair treated with shampoo containing water-soluble silicone demonstrated smoother sliding and better detangling, compared to shampoo with water-insoluble silicone, due to differences in conditioning film formation.

This study found that coconut oil significantly increased the tensile strength of twisted hair fibers due to its ability to penetrate the hair core, in contrast to mineral oil.

This study proposes a simple fluorescence method to evaluate hair damage and protection, suggesting that emissive properties of hair can aid in substantiating cosmetic claims.

This article discusses the characteristics of human hair, its damaging processes, and the potential repair effects of immuno-cosmeceuticals, but it reports no new clinical results.

This study found that bioconjugating 16-methylheptadecanoic acid (16-MHA) to damaged hair can mimic the protective properties of 18-methyleicosanoic acid (18-MEA), restoring the hair's structural integrity and moisture homeostasis, even after washing.

This review explores how radiation-induced hair graying can be used as a model to study the mechanisms behind hair graying, focusing on cellular senescence and potential therapeutic targets to address age-related changes. Results are not provided.

In this animal study, researchers found that exposure to a CO2 laser at various power levels caused significant skin damage in rats, including severe burns, coagulation, and tissue obliteration, with higher laser doses resulting in more pronounced injuries.

This study found that mackerel fermented fish oil protected human keratinocyte cells from UVB-induced oxidative stress by scavenging free radicals and reducing cellular damage.

This study found that hair damage from sunlight and chemical processes like perms and bleaching varies in internal microstructure changes, suggesting that protective techniques should be tailored to the type of chemical treatment used.

This paper suggests that using semiconical blades and coronal slits in hair transplantation may reduce vascular damage compared to other techniques, potentially offering optimal slit creation.

This study found that oxidative damage is present in the mitochondria of PolG mice, which exhibit premature aging-like phenotypes due to mitochondrial dysfunction.

This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.
