This study analyzed the swelling behavior of human hair during permanent waving treatment, finding that both the microstructure and macrostructure of intermediate filaments swell simultaneously at the initial stage, and while partially destructed by reduction, they are considerably restored through oxidation.

This study found that keratin coatings from human hair may improve the colony-forming efficiency of human mesenchymal stem cells by moderating donor variability, suggesting a potential use in clinical applications.

In this study, men seeking treatment for male pattern hair loss were highly concerned about their condition and had often attempted self-treatment, but many were dissatisfied with their physician consultations due to unmet expectations and perceived indifference from doctors.

In this study of captive rhesus macaques, social hair plucking was related to kinship, showed characteristics of both prosocial and aggressive behaviors, and was associated with alopecia and hair cortisol concentrations in females.

This study found that social hair plucking in captive rhesus macaques is linked to alopecia and possibly relates to stress in females.

This study observed that in captive rhesus macaques, social hair plucking is linked to alopecia and has kinship patterns similar to grooming, suggesting it may be socially influenced, though the health impacts and stress hormone (cortisol) changes involved remain uncertain.

This review highlights that hair's chemical bonds, particularly disulfide bonds, are not homogeneous, as previously thought, but instead vary in response to different cosmetic treatments, suggesting a need for further exploration of ionic bonds and hydrophobic interactions.

This study investigated the effect of peracetic acid treatment on hair fiber structure and found that disulfide bond oxidation altered thermal properties while preserving the α-crystal structure, suggesting different stabilizing interactions in hair fibers.

This study found that oxidative treatment with peracetic acid dissociates some disulfide bonds in human hair fibers while maintaining the crystalline structure, suggesting different mechanisms stabilize different regions of intermediate filaments.

This study found that social hair plucking in captive rhesus macaques was associated with alopecia and exhibited patterns similar to both prosocial and aggressive behaviors.

The conclusion is that the dermal papilla is crucial for hair follicle regrowth, and hair follicles undergo significant structural changes in addition to cell division during regeneration.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

This research discusses the function and culture of human dermal papilla cells, noting their unique in vitro characteristics and the ongoing efforts to understand their role in inducing hair growth.

In this study, keratin hydrogels derived from human hair were found to significantly enhance nerve regeneration in a mouse model, acting effectively as scaffolds by influencing Schwann cell behavior.

This study found that 1,2,3,4-tetrahydroquinoline derivatives, particularly N-methyl-7-amino-1,2,3,4-tetrahydroquinoline, may be excellent blue dye candidates for human hair, offering superior color purity, stability, and fastness compared to 2,3-dihydroindoles.

In this study, 84% of menopausal participants in England reported hair symptoms like shedding, thinning, and texture changes, with many seeking advice online and from nonmedical sources, highlighting the need for better information and support pathways.

This study found that among office workers in Seoul and Gyeonggi Province, hair loss stress significantly correlates with increased interest in appearance and consumption of scalp care products, with variations in impact depending on the type of stress experienced.

This article recommends creating a system to educate users about the ingredients and side effects of hair coloring products and does not report new research findings.

This study observed that among hair loss patients in Daejeon and Chungcheong, female pattern hair loss was most common, scalp massage was the preferred management behavior, and satisfaction was above average except for lower satisfaction with folk remedies.

In this study, supplementing adult Bichon Frises with 600 mg/kg Omega-3 PUFAs significantly improved their skin health, hair quality, feeding behavior, and metabolic health, compared to a control diet, over six weeks.

This study found that while all hair removal techniques increased axillary erythema and skin dryness, shaving caused less erythema but more dryness than plucking or waxing, without affecting post-inflammatory hyperpigmentation or other skin properties.

In this study, researchers developed a mathematical model of outer hair cell hair bundles that replicates experimental responses to mechanical stimuli, providing insights into the stimulus-dependent adaptation mechanisms and the functional significance of their three-row stereocilia configuration in mammalian hearing.

This study found that testosterone and dihydrotestosterone inhibit the growth rates of hair bulb papilla cells and root sheath fibroblasts, especially at higher doses, while estradiol was ineffective.

This study observed that among adults in their 20s and 30s, deteriorating scalp and hair health increased hair loss stress, which in turn prompted more proactive scalp care behaviors, with hair condition being a stronger motivator than scalp condition.

This article highlights the importance of recognizing, preventing, and reporting adverse drug reactions to the FDA's MedWatch program, but it presents no new research findings.
