This study demonstrates that keratinocyte cell lines derived from cultured hair follicles can fully differentiate in organotypic skin models, offering a minimally invasive alternative to obtaining keratinocytes for research.

This case report describes a six-year-old child with congenital biotinidase deficiency whose symptoms, including breathlessness, alopecia, and hearing loss, were reversed with biotin supplementation.

This study found that adding 10 mg/day of biotin to isotretinoin treatment for acne improved hair growth and maintained skin hydration, potentially reducing isotretinoin's mucocutaneous side effects.

This review summarizes causes and treatments of androgenetic alopecia with a focus on herbs as potential alternatives, but reports no new results and suggests more research is needed to validate these options.

This study found that human keratinocytes express a sodium-dependent multivitamin transporter for biotin, pantothenic acid, and lipoic acid, including a highly specific biotin transport component.

This article reviews various causes of hair loss linked to systemic factors, noting that careful history and examination can lead to accurate diagnosis, but reports no new clinical results.

This study found that a shampoo containing a 6-active ingredient complex increased β-Catenin production in human hair follicle dermal papilla cells to levels comparable to Finasteride, suggesting potential for promoting hair growth. It also showed good cleaning efficacy, volume, and shine in a sensorial study.

Eating a balanced diet with the right vitamins and minerals is important for healthy hair, but too many supplements can be harmful.

This study observed that smokers and alcohol consumers with androgenetic alopecia had significantly lower serum levels of antioxidant vitamins, and these habits may trigger earlier onset of alopecia in susceptible individuals.

This study reports that a low concentration of chitosan induces callose deposition and slows root hair growth in Arabidopsis, suggesting an evolutionary conservation of this response to mild biotic stress across plant types.

This study found that hemodialysis patients taking water-soluble vitamins had a 16% lower mortality risk compared to those not taking any, but the specific supplementation needed remains unclear.

This consensus paper reviews expert opinions on treating telogen effluvium but reports no new clinical findings.

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.

This review examines the impact of biotin, vitamin B12, and zinc on male reproduction, emphasizing their role in spermatogenic failure, but reports no new clinical results.

This study revisits and reproduces Felix Pinkus' concept of the vitreous membrane in hair follicles, suggesting these structures may play a role in differentiation or nutrition due to their location in metabolically dynamic regions.

In this study, transcutaneously applied nanoparticles and viral vectors were shown to penetrate murine hair follicles, internalize in antigen-presenting cells, and induce immune responses, suggesting a promising approach for vaccine delivery.

This research highlights the crucial roles of B vitamins in metabolism, neurological processes, and DNA functions, and describes emerging therapies that enhance vitamin absorption and therapeutic potential.

This study found that a 2% polyherbal phyto-complex cream containing aqueous extracts of Trichosanthes cucumerina and Abrus precatorius effectively promoted hair growth in preclinical tests, comparable to minoxidil 2%.

This review discusses the use of caffeine in cosmetics for its fat-reducing, antioxidant, and hair growth properties, but reports no new research findings.

This study found that multiple ion channel modulators, used here at clinical concentrations, increased intracellular calcium release in prostate and breast cancer cell lines.

This thesis investigates the underlying mechanisms and treatment options for androgenetic alopecia, highlighting the molecular roles of androgens and genetic predispositions, and evaluates current and emerging therapies, such as PROTACs and Janus Kinase inhibitors, to enhance patient management.

This study reviewed existing literature to provide comprehensive insights into diagnosing and managing alopecia areata, emphasizing the importance of understanding its classification, etiology, and the diverse treatment options available for improved patient care.

This study found that matriptase, a membrane serine protease, is crucial for maintaining multiple types of epithelial tissues in mice, with its absence leading to severe organ dysfunction and increased permeability.

This review examines skin symptoms, diagnosis, and treatment of zinc deficiency in children, proposing a classification system but reporting no new clinical results.

In this study, researchers identified a gene expression pre-pattern and implicated the Wnt inhibitor Dickkopf 4 in the formation of color patterns in domestic cat embryos.

This study on feather pattern formation in chicken skin found that inhibiting gap junctional intercellular communication can lead to the emergence of new feather buds in specific spatial patterns, suggesting that GJIC may facilitate Turing-type periodic patterning by propagating inhibitory signals over long distances.

This study found that inhibiting mTORC1 activity with rapamycin increased both hair growth and pigmentation in human scalp hair follicles, suggesting a potential strategy for treating greying and hair loss.

This study found that Manganese PCA, Cinchona succirubra, and Leontopodium alpinum extracts may promote hair growth by enhancing VEGF secretion and activating the Wnt/b-catenin pathway in Human Hair Follicle Dermal Papilla Cells.

This abstract presents the book "Buy Medical Physics in Aesthetic Medicine," which explores future innovations and techniques for cosmetic procedures expected in 2025, though specific findings or results from the book are not reported.

This paper offers a detailed overview of B vitamins, detailing their importance for energy, cognition, and metabolism, conditions leading to their deficiencies, symptoms of deficiencies, and the foods rich in these essential nutrients.
