This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This study in Hexi cashmere goats found that secondary follicle activity increases with time, and Hoxc13 expression varies significantly across different growth stages, suggesting a role in follicle activity.

A woman developed rare, unexplained curly hair on her scalp and eyelashes.

This study observed that in chicken skin, large-scale differences in gene expression between feathered and scaly skin are controlled by enhancer-driven uniform expression, while small-scale differences within individual feathers are associated with chromatin looping.

This study found that RCM combined with dermoscopy can differentiate disease states between alopecia areata, tinea capitis, nevus sebaceous, and linear scleroderma of the scalp by identifying distinct dermal and follicular patterns.

This study successfully cultured human fetal hair follicle-derived melanocytes, which showed high proliferative capabilities and unique morphological characteristics compared to adult-derived cells, potentially advancing hair disease research.

Uncombable hair syndrome causes dry, frizzy hair that can't be combed flat, seen in a young child.

Lichen planopilaris is a rare, chronic condition causing hair loss, mainly in middle-aged women, and early treatment is important to prevent permanent baldness.

This study uses cryo-electron microscopy to reveal how androgen receptor forms a non-obligate dimer to bind DNA, with implications for prostate cancer development.

This study examined the unique structural features of sinus hair follicles in the shrew Sorex unguiculatus, which suggest a specialization for vibration sensing.

This correspondence describes the dermoscopic features of an osteonevus of Nanta but does not report new clinical findings.

The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.

This study observed that follicular dysplasia in Weimar Pointers produces histopathological features and hair abnormalities similar to color dilution alopecia, though less severe.

Examining scalp tissue under a microscope helps diagnose and understand hair loss diseases.

This study found that the 16th-century mummified hair from a female mummy in Paju was remarkably well-preserved, with the hair's ultrastructural features maintained likely due to a calcium-rich surface coat.

This chapter highlights various commercial and open-source light sheet microscopy systems, detailing their rapid evolution and integration of multimodal technologies, with a focus on the ZEISS Lightsheet Z.1 system's advanced design for direct imaging and specialized sample mounting.

In this case study, electron microscopy revealed that harlequin ichthyosis involves giant mitochondria in keratinocytes and abnormal lamellar granule development, which may contribute to pathogenesis through altered lipid metabolism.

This publication provides a standardized nomenclature for classifying microscopic lesions in laboratory rat and mouse skin, aiming to harmonize international toxicological research.

In this study, researchers found that a low-cost USB dermoscope can effectively detect microscopic hair changes associated with early female pattern hair loss, making it a useful tool for diagnosis even without expensive equipment or programs.

This paper discusses the use of dermatoscopy as a fast, noninvasive technique for diagnosing hair shaft disorders and reports no new results; the authors highlight its advantages over traditional microscopy methods.

This article presents a protocol for using mouse tail skin to study hair follicle stem cells, enabling visualization of calcium signaling and other cellular features in various conditions but reports no new research data.

This research focused on Eclipta prostrata, revealing unique anatomical features and bioactive compounds such as alkaloids and flavonoids that can aid in reliable identification and quality control of this medicinal herb, commonly used for hair growth and liver health.

This study investigated the pharmacognostic characteristics of Adenostemma lavenia leaves, identifying key diagnostic features and confirming the presence of major phytoconstituents such as alkaloids and flavonoids, to help standardize this traditional medicinal herb.

This study found that ribbed hairs on tarantulas closely resemble chemoreceptors rather than silk-producing spigots, with no silk observed emitting from them under microscopy.

This study found that while ethnic hair types share a common fibrous keratin structure, variations in keratin-associated proteins and lipids may lead to different macroscopic hair characteristics.

This study found that the weak tensile strength of pili torti hair may result from loose keratin intermediate filaments due to abnormalities in disulfide bonds.

This study described the structure of the hair brush on male Endoclita vietnamensis moths' legs, identifying characteristics such as specialized scales and a pheromone gland, which could facilitate the future development of pheromone-based pest control methods for eucalyptus pests in China.

In this study, testosterone and certain metabolites were highly effective in promoting sebaceous structure growth in the female hamster flank organ, while others had limited or no effect.

This study identified significant differences in medullary structure, hair length, and root diameter among dorsal guard hairs of red foxes, golden jackals, and gray wolves in Turkey.

This study identifies various phytochemicals in Thuja orientalis bark, potentially aiding its botanical identification and quality standardization.
