This study found that polarized light microscopy is more effective than diffractive microscopy in distinguishing scarring from non-scarring alopecia, providing a highly specific adjunct diagnostic tool for alopecia biopsy specimens.

This study used advanced analytical techniques to reveal that proteins and lipids are distributed unevenly in hair, with distinct structural differences depending on their location within the fiber.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

This study shows that environmental contamination affects mummy hair, suggesting that using it to assess ancient people's health or nutrition should be approached cautiously.

The document concludes that hair keratin-chitosan scaffolds were successfully made and are suitable for biomedical use.

This article discusses the green synthesis of silver nanomaterials using Tridax procumbens and reports no new clinical findings.

This study found that freeze-dried finasteride nanoparticles significantly improved the dissolution rate and pharmacokinetic parameters compared to pure drug formulations, suggesting enhanced stability and solubility for poorly water-soluble drugs.

This study using an apertureless scanning near-field optical microscope found that dye restricted to hair's periphery remains mainly on the surface and in the endocuticle.

This review discusses recent advances in understanding the structural hierarchy of trichocyte keratins, including their heterodimeric structure and distinct conformations impacting hair growth, with no new experimental results reported.

This study found that hair luster decreases with age in Japanese females, primarily due to an irregular increase in fiber curvature which affects hair alignment.

This study characterized hair from a patient with a ribosomopathy and identified distinct differences, including reduced hair thickness and lipid content, compared to family members.

This review discusses fractionated reirradiation as a potential treatment for recurrent brain tumors in children and highlights ongoing challenges with managing craniospinal dissemination; it provides no new clinical results.

This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.

This review discusses the development and application of multiphoton microscopy in dermatology, highlighting its advantages and potential future research directions without reporting new clinical results.

Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.

This review discusses the role of hair microscopy in diagnosing alopecia, stating that while it excludes diagnoses related to hair breakage, it only confirms nonspecific short anagen in alopecia cases.

A specific hair diffraction pattern may indicate breast cancer if tested with the correct method.

This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.
