This study found that hair treatments applied after chlorination, especially bleaching and dyeing, more significantly altered surface properties and weight loss, while perming most strongly affected tensile properties.

This article reviews the cutaneous side effects of immune checkpoint inhibitors and targeted therapies for skin cancers, noting that while generally mild, these effects can influence treatment decisions and quality of life, underscoring the need for physicians to be aware of these adverse reactions.

This chapter reviews skin manifestations in common rheumatic diseases, particularly those with polyarthritis, and offers a differential diagnosis of erythema nodosum without presenting new research findings.

This study found a specific T cell receptor that may be key in carbamazepine-induced Stevens-Johnson syndrome and toxic epidermal necrolysis, suggesting potential therapeutic targets.

This article discusses the relationship between topical sunscreen use and vitamin D synthesis but reports no new clinical results.

This review outlines the major health consequences of anabolic-androgenic steroid abuse, with a focus on sexual and reproductive issues, and suggests management prioritizes cessation and relapse prevention due to lack of robust randomized trials.

This study found that formulations containing pequi and buriti oils improved texture properties and significantly increased gloss in curly hair, with pequi oil also significantly enhancing tensile strength.

This study found that novel thiol-reactive cross-linking agents, particularly APA, significantly improved the tensile strength and elasticity of human hair fibers by effectively regenerating disulfide bridges, with potential applications for advanced hair repair treatments in the cosmetic industry.

In this study, researchers observed that even a single session of hair dyeing can damage hair fibers, with significant worsening of mechanical properties and protein composition after three or more consecutive treatments, emphasizing the need to consider the cumulative impacts of dyeing on hair health.

In this study, a bleaching protocol was developed to evaluate hair repair products, revealing that K18® and Olaplex® improve hair brightness and lightness, with distinct impacts on hair fiber properties.

This study found that temperature significantly affects the mechanical properties of rabbit hair fibers, with increased tensile strain and decreased breaking strength in humid conditions.

This study found that deep plane fixation in scalp surgeries allowed for tension-reduced wound closures and increased tissue excision compared to techniques without deep plane fixation.

In this study, researchers observed that Sedum takesimense extract improved the surface properties, moisture retention, tensile strength, and wave formation of damaged hair compared to a water control, even after additional chemical and UV damage, suggesting its potential as a protective hair treatment.

In this study, a liposomal-encapsulated Sesbania grandiflora formulation significantly improved hair and scalp health in adults with hair loss over 180 days, showing enhanced hair density, thickness, growth rate, and tensile strength compared to placebo, with no related adverse events reported.

This study found that the liposomal Sesbania grandiflora formulation significantly improved hair and scalp health in adults with hair loss compared to placebo over 180 days, enhancing factors such as hair density, thickness, growth rate, and tensile strength, with no related adverse events reported.

This study proposed a new standardized in vitro framework using human hair tresses to evaluate cosmetic hair product performance and found significant improvements in hair breakage, tensile strength, shine, volume, and frizz control compared to a control group without such changes.

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.

This review evaluates photobiomodulation's diverse clinical uses in sports and medicine, reporting physiological modulation and potential therapeutic benefits, but emphasizes the importance of precise dosimetry for success.

In this comprehensive review, researchers reported that macromolecules like type I collagen, keratin, and ceramides enhance hair health by improving follicular function and increasing hair density, strength, shine, and resilience, as shown in various in vitro, animal, and human studies.

In this 24-week study, oral supplementation with hydrolyzed low-molecular-weight porcine placental peptides significantly improved scalp elasticity, hair diameter, tensile strength, surface roughness, and luster compared to placebo, suggesting its potential as a nutritional intervention for age-related scalp and hair changes.

This study found that the viscosity of silicone oil in hair treatments significantly affects wave curling performance and hair damage, with untreated and chemically treated hair showing different optimal viscosities.

This study observed that treating human hair with NaOH led to partially removed cuticles, resulting in better fiber cohesion and mechanical properties similar to wool, unlike bleach or formic acid treatments, which weakened the fibers.

In this study, adults with mild-to-moderate hair damage taking GPVGPS Collagen® daily for 24 weeks showed significant improvements in hair luster, strength, thickness, and density compared to placebo, with no safety concerns reported.

This study found that treating damaged hair with maleic-modified amino silicone oil created a highly hydrophobic surface, reducing water content and improving hair's mechanical properties and thermal stability.

This study found that platelet-rich plasma therapy significantly improved hair density, diameter, and reduced inflammation in androgenetic alopecia patients compared to placebo, though individual responses varied.

This study assessed the effects of chemical treatments on hair fiber integrity and found that conditioners with vegetable oils like jojoba and coconut enhanced hydrophobicity and reduced combing friction except for jojoba, while participants preferred these oil-containing conditioners over the base formulation.

In this study, researchers found that mangosteen pericarp extract, combined with FeSO₄ as a mordant, effectively produced a stable reddish hair dye on bleached hair, with good color persistence and enhanced tensile strength, indicating its potential as an eco-friendly and safer alternative to synthetic dyes.

In a laboratory study, researchers found that a novel Bioactive Crosslink Repair Complex improved both the protection and repair of chemically damaged hair, enhancing tensile strength, shine, and cuticle alignment when added to bleaching mixtures and leave-in conditioners.

This study found that applying soybean oil extract to damaged hair significantly improved brightness, tensile strength, absorbance, and gloss, suggesting its potential in enhancing hair condition. Further research is needed to explore how different natural extracts affect damaged hair.

This study outlines how combined ultrasonic and infrared hair treatments may enhance hair restoration and performance by breaking down keratin disulfide bonds for better treatment access and sealing cuticle scales to preserve improvements, with potential applications in salon and home settings.
