This study developed a quantitative measure for scoring hair surface damage from SEM images and found it accurately classified hair damage caused by explosive blasts, similar to an existing classification system.

This study found that L-cystine-modified rabbit hair fibers had improved dye adsorption and spinnability, due to changes in secondary structure and surface characteristics.

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.

In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This review evaluates the scientific literature on silicon supplements, noting that orthosilicic acid shows higher bioavailability, but emphasizes the need for further clinical studies on safety and efficacy.

This study found that mesotherapy with a dutasteride-containing preparation improved hair growth indicators in female pattern hair loss better than saline, with minimal side effects and greater effectiveness in patients with shorter disease duration.

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.

This study's molecular dynamics simulations suggest that electrostatic interactions mainly stabilize peptide binding to human hair keratin, with the protein's dielectric constant significantly affecting free energy calculations.

This study found that the ocular surface epithelium in mice contains distinct stem cell populations with unique cell division dynamics that change behaviorally in response to different levels of injury.

This review article highlights how hair follicle-targeting drug delivery systems enhance therapeutic outcomes and reduce side effects for treating conditions like androgenetic alopecia and acne vulgaris. The authors discuss current formulations and evaluate their performance in both preclinical and clinical settings.

In this study, women with acute telogen effluvium taking the Hair’InsideTM supplement for 84 days showed significant improvements in hair regrowth, shedding, brightness, and volume compared to placebo, with no reported adverse effects.

This study found that adult mouse dermis can be reprogrammed by epidermal cues to resemble neonatal dermis, with changes in fibroblast proliferation and extracellular matrix composition.

The authors concluded that their new grading system can effectively classify early female pattern hair loss and evaluate treatment progress.

This study conducted a comprehensive analysis of methods for assessing surface roughness, highlighting that contact methods using profilometers provide accurate results for machine parts, while non-contact optical and laser methods offer high precision and efficiency without damaging surfaces.

This study found that a 12-week supplementation with MePL, a solution of miliacin encapsulated within polar lipids, significantly reduced hair density in the telogen phase and improved scalp dryness and hair brightness in women with telogen effluvium.

This study reported a rare case of necrobiosis lipoidica occurring on the scalp, leading to scarring alopecia, and highlighted a positive response to glucocorticoid therapy by reducing the brightness and growth of plaques over one month.

This study demonstrated that intradermal treatment with a medical device using Polynucleotides High Purification Technology (PN HPT) significantly improved skin surface, firmness, pigmentation, and radiance in 30 Asian subjects, with benefits lasting up to six months and no adverse events reported.

This study found that incorporating CTA2-BADG, a modified hair-rebonding compound, into damaged hair significantly improved surface morphology and tensile strength by using charge-conversion chemistry to enhance penetration into the hair shaft.

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.

This study found that keratin-based particles were able to recover and enhance the mechanical properties and thermal stability of virgin and overbleached Asian hair, improving its strength and smoothness by around 40%, and demonstrated safety in human skin keratinocytes.

This study formulated an herbal shampoo using natural extracts and compared its physicochemical properties, such as pH and foam consistency, with commercial shampoos, finding that both performed similarly in conditioning tests conducted with twenty volunteers.

This review discusses various nanocarriers for gene and genome editing therapies, highlighting that ionizable lipid nanoparticles show advanced delivery performance, while emerging polymer-based and exosome-inspired carriers are rapidly advancing for targeted applications.

Image analysis can effectively identify changes in scalps affected by chemotherapy-induced hair loss.

In this study, researchers found that the primary cause of slippage and detachment of keratin capsules in hair extensions is the re-contamination by oily residues from the hairdresser's hands, rather than the use of hair care products like masks or conditioners.

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 oxidative hair dyes altered the color and ultrastructure of Caucasian hair but did not significantly affect the hair's breaking strength.

This study investigated the effects of ammonium thioglycolate and amino methylpropanol hair straightening followed by permanent coloring, finding significant physical and chemical changes to both the cuticle and cortex of hair fibers.

This study found that ultraviolet A rays damage all hair types, with stronger adverse effects on colored and permanently waved hair, suggesting the use of sunblock products for hair protection.

This study found that polyamidoamine dendrimers can permeate skin's current conducting pores and alter the magnitude and direction of electroosmotic flow, affecting drug flux during iontophoresis.
