This study found that permanent waving treatment partially disrupts the α-helical structure in human hair microfibrils, primarily during the initial reduction phase, rather than just affecting disulphide bonds.

This study reported that the treatment of hair with glyoxylic acid straighteners causes major conformational changes within the hair fiber due to interactions between carbonyl and keratin components.

This study observed that mercury-lamp irradiation may cause cleavage of disulfide bonds in keratins of white hair, leading to the formation of thiols in laboratory settings.

This review discusses in vitro methods for evaluating the effects of hair care products on hair fibers, reporting no new results; the authors emphasize the importance of selecting appropriate and accurate equipment for testing.

In this study, researchers developed a method using scalp cyanoacrylate biopsy and advanced imaging techniques to effectively measure and visualize the distribution of anti-dandruff shampoo ingredients zinc pyrithione and climbazole within the scalp follicular infundibulum.

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.

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 reported that the calculated and experimental electronic and vibrational properties of minoxidil were in good agreement, providing detailed insights into its molecular structure and thermal behaviors.

This study used Raman spectroscopy and wide-angle X-ray scattering to observe two main α-helix to β-sheet transitions in hair keratin under varying humidity levels, finding that water impacts when these structural changes occur, involving a disordered state.

This pilot study found that prebleaching either virgin or previously colored hair only slightly affects the SERS spectra of dyes applied afterward, without impacting the accuracy of dye identification, supporting the technique's robustness for forensic analysis of hair dyes.

This study developed a new suspended ointment formulation containing neomycin sulfate and triamcinolone acetonide, which showed promise for treating neurodermatitis and chronic eczema by ensuring stable composition, effective skin penetration, and no skin irritation.

In this study, reducing agents like ammonium thioglycolate, L-cysteine, and sodium sulfite in shampoo effectively decreased hair flyaway and frizz without causing damage, as no critical hair damage was observed in structural and tensile strength assessments.

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.
