This study found that using an aqueous solution of AMPD in hair bleach reduced both hair damage and odor compared to ammonium hydroxide.

This study found that a wheat-protein based herbal shampoo with natural ingredients demonstrated good conditioning performance, cleansing properties, and surface tension, helping to clear dirt, dandruff, and promote hair strength and darkness without causing hair damage, but further work is needed to enhance its quality.

This study found that a hair treatment cream using keratin protein from chicken feathers effectively improved damaged hair, particularly by repairing the surface layer.

In scalded rats, this study found that early melatonin administration may reduce oxidative stress and inflammation, thus protecting hair follicle cells after severe burns.

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.

In this study, combined treatment with transglutaminase and keratin significantly repaired damaged hair by improving its structural properties, reducing swelling, and enhancing crosslink activities, as evidenced by microscopy and spectroscopy analyses.

This study used molecular dynamics simulations to illustrate the complex molecular behavior of the hair surface F-layer, highlighting how fatty acids interact with 18-MEA under different conditions.

This study found that a conditioner containing 18-MEA and SPDA can improve hair's smoothness and reduce flyaways, enhancing hair manageability.

In this study, adding conditioning agents PA1, PA2, and PA3 to light blonde oxidative hair dyes improved combability and protein retention of light brown hair without affecting tensile strength, though PA1 and PA2 offered enhanced thermal protection.

This study utilized a fluorescence probe to evaluate cysteine formation on hair fibers, finding that optimal fluorescence emission occurred at pH 4.5.

This study found that the ocular surface epithelium in mice contains distinct stem cell populations with unique cell division dynamics that change behaviorally in response to different levels of injury.

This study found that bioconjugating 16-methylheptadecanoic acid to damaged human hair can mimic the protective function of the original 18-methyleicosanoic acid, effectively restoring both the hair's external structural integrity and its internal moisture balance.

This study reported that distinct stem/progenitor populations in the ocular surface epithelium have different cell division frequencies and respond differently to injury, with specific spatial compartmentalization and migration behaviors.

This study investigated the effects of a derma pen treatment using green betel leaf extract cream on hair development in female Wistar rats, highlighting the antioxidant and anti-inflammatory properties of betel leaves that may aid in hair growth and condition.

This study found that applying a hair mist with dandelion extract before heat perming improved wave efficiency, tensile strength, and hair cuticle condition compared to a base mist or no pretreatment, demonstrating the extract's protective effects against heat damage.

This study found that wool fiber surfaces damaged in processing tended to have cellular debris adhering to them, while undamaged surfaces did not show this interaction.

This study found that two shampoos with different dyeing methods had varying abilities to dye hair and impact hair health, suggesting that individuals should select hair color shampoos based on their personal needs.

This study found that a combination of Ziziphus lotus, Linum usitatissimum, and Opuntia ficus-indica extracts may reduce porosity and improve surface condition in bleached hair when used as a conditioner.

This study found that heating damages Asian black male and female hair cuticles without altering their structure, with damage severity increasing at higher temperatures and longer exposure times.

This review discusses the mechanisms by which sunlight exposure aggravates hair aging and highlights the role of hair pigments in providing photochemical protection, reporting no new results.

This study found that treating yak hair fibers with low-temperature plasma and microwaves weakened the scale structure and significantly improved dyeability.

This study evaluated a hair mask containing rice germ oil GX-N and ferulic acid on damaged hair and found that rice germ oil GX-N improved hair characteristics after bleaching, UV, and heat exposure, but adding ferulic acid did not provide extra benefits.

This study analyzed the nanotribological properties of various hair types and human skin, revealing differences in friction and adhesion based on ethnicity and hair condition.

This study highlights confocal microscopy as a promising, minimally invasive tool for assessing hair morphology and internal structures, making it valuable for cosmetic hair assessments.

This study reports that a plant extract from Orobanche rapum can stimulate skin rejuvenation and protect cutaneous microbiota, potentially creating healthier skin.

This review discusses the use of zebrafish larvae as an alternative model for studying ototoxicity, facilitating large-scale screening for otoprotective compounds, but reports no new clinical results.

This review discusses the causes of hair shaft abnormalities and highlights the role of cosmetic products in treating hair disorders, though it reports no new clinical findings.

This study reported that a bioderived melanoidin/tannic acid nanocomplex forms a durable, antioxidant-active coating on hair fibers, providing enhanced UV protection and improving tensile resilience by suppressing oxidative stress and activating endogenous antioxidant pathways.

Applying pseudoceramide improved skin and hair health.

This study in neonatal chicks reported that intense sound exposure severely impaired auditory function, but function returned to near normal within 3 days, primarily due to non-hair-cell mechanisms.
