This study observed that using a relaxed suture technique on scalp incisions may prevent linear scars by reducing pressure on upper stem cells.

This review discusses the limitations of current hair classification systems and highlights the need for standardized reporting of key hair characteristics to improve study comparisons; it reports no new results.

This study found that the tensile strength of curly hair is influenced by two main components, with springiness (toe region) contributing significantly, unlike in noncurly hair where it is negligible.

This study found that keratin intermediate filaments in the hair of GAN patients are altered, showing decreased diffraction signals and increased stiffness, strength, and extensibility.

This study investigated the effects of wool-derived hydrolysed keratin peptides on relaxed textured hair and found that mid- and high-molecular weight peptides improved mechanical strength and reduced breakage in different humidity conditions.

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.

Traction alopecia is hair loss from pulling on hair too much.

This study found that Argan oil conditioner significantly enhanced tensile strength and retained hair color in bleached hair more effectively than Camellia oil.

This study discusses the effects of incorporating various amino acids in hair care products, noting improvements in hair surface properties and color retention when integrated with conditioners.

This study described a new wig coating technique using keratin and graphene oxide that significantly enhanced UV resistance, antistatic properties, and durability compared to traditional methods.

This study found that a new eco-friendly hair crosslinking method using visible light and non-toxic chemicals caused less damage and improved mechanical properties compared to traditional thioglycolic acid treatment.

In this study, a method using riboflavin phosphate, citric acid, and polyols successfully optimized protein cross-linking in hair of all colors through visible light-mediated photo-cross-linking, improving the mechanical properties and hair-setting effects without the influence of hair color.

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.

In this study, tresses treated with pH 1.0 acid straightener showed better straightening but more damage to hair properties compared to those treated with pH 2.0.

In this study, applying the microbial enzyme transglutaminase from Streptomyces mobaraensis to damaged hair increased its tensile strength by 15.64%, suggesting potential benefits in repairing shampoo-induced damage and improving hair luster.

This study found that digital perm treatments using sodium thioglycolate lotion led to the most significant reduction in protein content and greater hair damage compared to other methods and lotions.

This study found that using cationic and non-ionic polymers during alkaline hair relaxer treatments may help strengthen hair and control swelling, potentially reducing damage.

The authors suggest that male-pattern hair loss may be linked to neuropathy caused by tension on scalp nerves, potentially worsened by testosterone, and propose electrical stimulation as a temporary treatment.

This article reviews therapeutic methods for managing non-cicatricial alopecia associated with various conditions and provides no new clinical results.

This study found that large excisional wounds in mice can regenerate new hair follicles and fat, whereas similar wounds in rats across seven strains failed to do so, highlighting interspecies differences in regenerative capacity.

This study found that increasing collagen concentration to 2% in permanent wave treatments reduced hair damage but impaired curl formation.

In this study, researchers linked hair composition and mechanical properties to perceived hair quality, suggesting that hair quality may be genetically determined.

This study found that integrating graphene oxide into a biodegradable composite made from discarded hair keratin enhanced its structural properties, biodegradability, and gas barrier performance, indicating potential use as an eco-friendly packaging material.

The authors reported that certain cosmetic procedures can lead to secondary alopecia, and suggested dermatologists play a crucial role in managing these complications and raising awareness about potential adverse effects.

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 TRP-hair essence significantly protected and improved the quality of human hair, particularly against heat stress, by enhancing cuticle health and maintaining hair color.

This study found that low-molecular-weight hyaluronate significantly improved the mechanical strength and elastic modulus of overbleached hair by enhancing hydrogen bond networks within keratin.

In this study, researchers found that using 0.75% aspartic acid as an intermediate agent for a permanent wave improved wave formation and retention compared to a control in virgin hair, also reducing cuticle damage and maintaining tensile strength.

In this study, researchers developed a regression model that reasonably predicts consumer-perceived hair breakage using various parameters such as hair smoothness, detangling forces, extensional strength, and hair density among Indian women.

This study found that a 2.5% flavonoid-rich extract of Equisetum hyemale promoted hair growth in a rat model of chemically-induced alopecia, showing results comparable to 5% minoxidil.
