This study suggests that elevated copper levels in domestic tapwater, exacerbated by its aggressive properties, likely contribute to green hair by damaging the cuticle and increasing copper uptake.

This review discusses the use of hair microscopy in diagnosing hair-related conditions, highlighting techniques and common applications, but presents no new experimental results.

This study found that nano-sized lipid particles improved the skin accumulation and retention of dexamethasone compared to a base cream, suggesting potential benefits for inflammatory skin disease treatment.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

This study observed that black-haired areas in female Saluki puppies developed hypotrichosis, with dilated hair follicles containing melanin clumps, while white-haired areas remained normal.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This article reviews various diagnostic tools for hair disorders, describing methods ranging from invasive to noninvasive, but reports no new research findings or clinical results.

This study examined developing hair cortex with electron microscopy and found that keratin fibrils form between specific regions in hair follicles and aggregate into twisted cables.

This article discusses using cosmetic hair products alongside medical treatments for hair conditions to enhance patient self-esteem and quality of life, without reporting new clinical results.

This study found that Piezo2 channels are primarily located on sensory axon membranes in mechanosensory end organs, supporting a model where mechanical stimuli activate Aβ RA-LTMR neurons via axon protrusions.

This review discusses hair shaft disorders, noting the lack of specific treatments and recommending general care practices to prevent hair damage, with some improvement possible during puberty or with treatments like minoxidil.

The document concludes that the trichogram is a useful tool for diagnosing hair loss and suggests semi-organ cultures for practical trichological research.

This study found that distinct hair fiber structures among blue fox, mink, and otter rabbit can be used to identify and differentiate these fur types.

This paper reviews various techniques for measuring the physical and mechanical properties of human hair fibers, emphasizing their importance in developing effective cosmetic products.

This biographical abstract highlights George Rogers' pioneering contributions to the understanding of keratin molecular structure and keratinisation biochemistry, including the application of electron microscopy to hair ultrastructure and the discovery of enzymes and gene transcription processes relevant to keratin proteins.

In this study, ultrastructural examination of hair in children treated with valproic acid showed a normal hair surface and cuticular pattern, despite reported hair changes with the drug.

This study found that sonography and electron microscopy revealed distinct abnormalities in hair follicle morphology in patients with androgenetic alopecia, which may aid in diagnosing and managing the condition.

This study observed that particles sized 300-600 nm penetrate hair follicles more efficiently, likely due to alignment with the thickness of the human hair cuticula.

This study describes trichilemmal keratinization as a distinct process of hair follicle keratinization that occurs in specific areas of the outer root sheath, illustrated using electron microscopy on dog hair.

This case report describes the characteristic clinicopathological features of trichodysplasia spinulosa in two boys with acute lymphocytic leukemia, highlighting its resolution as immune function normalizes.

This article explores the use of monoclonal antibodies to study the presence and distribution patterns of melanocytes in developing human skin, but reports no new clinical results.

Hair and follicle keratins differ in structure and expression, especially in cysteine content.

This study discovered that the lipid in human hair follicles is mainly located in the hair cuticle and keratinized inner root sheath, distinct from sebaceous and epidermal lipids, suggesting a potential role as a "hair barrier.

This study suggests that spiny keratoderma may be an ectopic hair formation on palms and soles, based on keratinization patterns observed using antikeratin antibodies and electron microscopy.

In this study, researchers found that alpha-keratin homologs similar to those in mammalian hair are present in the claws of the lizard Anolis carolinensis, suggesting a structural role during claw formation.

This study examined two cases of bubble hair deformity using light and electron microscopy, suggesting that trauma to the hair shaft may contribute to this condition.

This study examined hair curvature in Japanese women, finding that 47% have curved hair, and identified structural differences in hair fiber, which resemble those in wool fibers.

In this study, topical minoxidil was reported to increase fenestration in follicular capillary walls around anagen hair bulbs in male rats.

This study found that applying a mix of cholesterol and Tween 60 detergent to mouse skin significantly reduced epidermal cell mitotic activity.

The document concludes that hair analysis is not good for assessing nutrition but can detect long-term heavy metal exposure.
