This study found that biotinoyl tripeptide-1-loaded solid lipid nanoparticles significantly improved thermal protection in hair, enhancing cuticle integrity and resistance to heat damage, compared to control samples.

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 reviews the biology and cosmetic treatment of hair, emphasizing future advancements in safer, more effective procedures to meet consumer needs for hair care.

This study explored a multidimensional approach to examine body hairs' physico-chemical properties, potentially supporting their use over scalp hairs in forensic and intoxication studies.

This study reported that fermented grapeseed oil may enhance hair permeability and improve strength and color retention in chemically treated hair compared to regular grapeseed or silicone oils.

This study found that chemical hair straightening significantly reduced hair curl and improved smoothness and shine, but did not significantly affect transverse fissures or split ends, indicating potential benefits with some side effects.

This study found that a peptide treatment using Protein disulphide isomerase improved the mechanical and thermal properties of over-bleached hair by promoting deeper peptide penetration and attachment.

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.

This review discusses the use of ceramic-coated flat irons for hair straightening and reports no clinical results; the authors highlight potential hair damage risks from improper use.

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.

This study found that a genetic variant in the EDAR gene leads to typical East Asian hair characteristics by increasing signaling output, as shown in transgenic mice experiments.

In this study, researchers found that a protein-enriched cream made from Spirulina platensis improved the physical structure of natural hair, as evidenced by more intact and smoother cuticles compared to a control cream without protein, suggesting its potential for hair care applications.

This study found that a sucrose-based crosslinker can effectively straighten hair and maintain durability in high humidity and through repeated washings without affecting the hair's tensile properties or causing surface damage.

This study found that treating hair with ATS, formed from fumaric acid and cysteamine, effectively improved hair quality by increasing moisture content and altering the internal structure of strong curls.

This study found that 1,4-n-butylene dimaleate can restore the mechanical properties of reduced hair by reconnecting disulfide bonds and improving the hair's structural integrity using a thiol-Michael click reaction, compared to untreated reduced hair.

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.
