This article reviews dermatological research on black skin, emphasizing its unique physiological characteristics and common conditions like acne and eczema, and suggests more focus is needed on its structural differences and clinical responses.

This study found that treating human hair with vitamin E and γ-oryzanol significantly reduced UV-B-induced structural damage, with γ-oryzanol providing greater protection, especially in female hair samples. The findings highlight these compounds' potential as cost-effective solutions for preserving hair integrity against UV damage.

This study identified key molecular differences between Long and Short hair type cashmere goats, suggesting hair type differentiation is linked to structural assembly and follicle remodeling.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

In this study, synchrotron-powered infrared microscopy revealed that hair follicles are a favored penetration pathway for cyanophenol and ethylhexyl methoxycinnamate in human skin, without altering protein secondary structure.

This study reports the successful differentiation of mouse induced pluripotent stem cells into keratinocytes that can regenerate skin and its structures in an in vivo environment.

This study reports various immunophenotypical patterns in apocrine mixed skin tumors, resembling the structures of hair follicles, sebaceous glands, and apocrine glands.

This study concluded that the hairless protein interacts with the vitamin D receptor to repress transcription crucial for hair cycling, employing multiple protein interfaces and modulating chromatin structure.

This study found that Wnt ligands from CD133-positive dermal papilla cells are essential for maintaining hair growth by supporting cell signaling between different hair follicle structures.

This research suggests that both proposed pathways into hair fibers for molecule penetration are valid and complementary, with all fiber structures acting as potential routes for delivering materials.

This study developed a zinc-infused egg white and GelMA hydrogel that enhanced cellular processes crucial for wound healing, including fibroblast proliferation and collagen expression, and demonstrated promising biocompatibility and bioactivity in vivo, suggesting potential effectiveness in repairing damaged tissues.

This study investigated the immunohistochemical characteristics of keratin proteins in epidermal appendages, finding variable staining patterns in different skin structures and tumor cells, which suggests differences in keratinization.

This study found that treating hair with ATS, formed from fumaric acid and cysteamine, effectively improved hair quality by increasing moisture content and altering the internal structure of strong curls.

This study found that fish oil supplementation in male Wistar albino rats helped maintain hair shaft structure and improved amino acid composition, while reducing harmful protein compounds associated with diabetes and hypercholesterolemia.

Specific cross-linkages help make hair proteins stable and strong.

This study found that about 80% of known fullerene-binding proteins rank in the top 10% of scorers for C60 docking sites, confirming the accuracy of the predictive model used.

In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

Vertebrate skin evolved to be more specialized and complex, especially in land animals.

This study found that trichothiodystrophic hair shows reduced and disoriented protein deposition in follicles, with both the cuticle and cortex affected, providing localized structural insights into keratin abnormalities.

This review highlights the limited research on sebocyte lipid droplets and their proteins despite their role in sebocyte differentiation and potential involvement in skin diseases like acne and alopecia, and reports no new results.

This review summarizes recent research on the molecular properties and functions of L-PGDS and PGD2, but reports no new findings, highlighting their pathophysiological roles and guiding future studies.

This study characterized the Hoxc-13 gene from sheep wool follicles, noting its potential autoregulatory role and potential influence on skin function beyond hair keratin regulation.

In a study on diabetic mice, researchers developed a protein-based hydrogel that leverages zinc ions and the natural compound phellopterin to promote cutaneous nerve regeneration, angiogenesis, and tissue remodeling in diabetic wounds, highlighting its potential for advanced wound therapy.

KAP genes are crucial for hair development and show both shared and unique traits in humans, chimpanzees, and baboons.

Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.

In this study, Apricot Kernel Oil treatment in Wistar rats showed dose-dependent improvements for seborrheic dermatitis induced by DNFB, including reduced inflammation and oxidative stress and enhanced skin structure.

This study utilized the DNP–SANS technique on human hair for the first time and found significant changes in the SANS profile dependent on polarization conditions, providing insights into the structural composition and dynamic properties of keratin and its associated proteins.

This study found that sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.

This review explores how epidermal stem cells contribute to the development and maintenance of various skin structures, and highlights specific markers and proteins associated with these cells, but reports no new clinical results.
