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 review discusses the potential of using human hair proteomics for non-invasive diagnostic and forensic applications but reports no new results; the authors highlight areas needing further research.

This study suggests that ATR-FT-IR spectral analysis of hair fibres may detect breast cancer through increased lipid content changes linked to cancer presence.

This study found that human hair cuticle and cortex have different protein structures, with beta-sheet and disorder configurations in the cuticle and alpha-helical structures in the cortex.

This study identified various functional groups and chemical constituents in dried leaves of the medicinal plant Bhringaraj, suggesting their potential use in developing wastewater treatment technologies.

This study found that using a microfiber towel to dry human hair better preserves hair keratin integrity and wear resistance compared to blow-drying or using a cotton towel, as indicated by stronger alpha-helix structure in FTIR analysis.

This study developed a new finasteride release system using chitosan-based nanoniosomes, observing that 70% of the drug was released over ten days in vitro, suggesting potential for prostate cancer prevention.

In this study, researchers found that silica nanoparticles synthesized using cold plasma showed a higher biofilm inhibition effect on Staphylococcus aureus and Escherichia coli compared to those made with a magnetic stirrer.

In this study, researchers formulated an herbal antidandruff shampoo using plant extracts like neem, fenugreek seed, aloe vera, and clove, demonstrating its antifungal activity against Malassezia furfur and potential as a natural alternative for addressing dandruff.

This study developed plant-pigment-based shampoos using extracts from Neem, Fenugreek, Hibiscus, and Butterfly Pea, which demonstrated stability, antimicrobial properties, and potential scalp benefits such as hair growth promotion and dandruff reduction, making them a promising alternative to synthetic dyes.

This study found that oxybenzone is very stable under light exposure, contradicting previous findings of its oxidation to semiquinone after solar irradiation.

Finasteride's polymorphic form affects capsule quality and drug effect, requiring strict control.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

This study found that ATR-FTIR spectroscopy combined with machine learning effectively differentiated alopecia areata patients from healthy controls with an AUC of 0.85, and also showed promise in predicting treatment response, particularly through alterations in the Amide I band.

This study observed that the molecular structure of keratins in hair fibres' discrete transition zone differs in breast cancer patients, with altered lipid ester absorption bands reverting post-cancer removal.

Lower acetylation makes chitin nanofibers thinner and more suitable for various uses.

In this study, researchers developed a method called the Stiffness-Angle Law and found that hair treated with caffeine-infused shampoo showed a 13.2% increase in stiffness, as measured by their novel evaluation technique.

This study found a high prevalence of hyperandrogenemia in women with PCOS, with distinct biochemical differences according to BMI and presence of hyperandrogenemia.

PEVs effectively deliver minoxidil through skin.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

This study observed that repeated perm treatments decrease disulfide bonds in hair due to their conversion largely into cysteic acid, affecting the waving efficiency depending on the reduction agent used.

In this study, UVB exposure was found to alter certain chemical properties of the hair shaft, such as keratin components and water content, without significantly affecting its physical morphology.

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.

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.

This study provides conclusive evidence of exogenous calcium fatty acid deposits forming between the cuticle layers in hair, affecting its optical and mechanical properties.

This study observed that lipids in human hair accumulate in specific areas and do not significantly impact water permeability, highlighting the utility of AFMIR for studying complex biomaterials.

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 developed a spectrophotometric method to determine minoxidil in pharmaceuticals, creating a highly sensitive, simple, and cost-effective approach using a synthesized charge transfer complex with a notable absorption peak at 505 nm.
