This review discusses the evolution and ongoing debate about the causes of central centrifugal cicatricial alopecia in African American women, without presenting new clinical findings.

This study found that Sophora flavescens extract may promote hair growth in mice by inducing earlier hair cycle changes and regulating growth factors in dermal papilla cells.

In this study, researchers found that depleting mtDNA in mice caused skin wrinkles and hair loss but restoring mitochondrial function reversed these effects, highlighting mtDNA's significant role in skin and hair health.

This case report describes a 10-month-old boy with dermatitis, alopecia, and hypotonia who showed dramatic improvement with oral biotin, suggesting a possible defect in biotin absorption or transport.

This review discusses the use of mushrooms and their bioactive compounds in cosmeceuticals and nutricosmetics and reports no new clinical findings, highlighting potential areas for future research and development.

This study identified that a deficiency in the palmitoyl transferase enzyme, due to a mutation in the Zdhhc13 gene, led to severe physiological abnormalities in mice, including skin, bone, and systemic amyloid issues.

This study observed that human hair follicles were able to regenerate fiber-forming structures after the bulb was amputated and transplanted onto athymic mice, suggesting a general regenerative capacity.

This study found that short-chain fatty acids produced by the skin microbe Propionibacterium acnes may drive inflammatory gene expression in sebocytes, potentially contributing to acne.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

This study explored the interaction between androgen and Wnt signaling in dermal papilla cells, targeting the effects of androgen on hair growth reduction.

This review discusses genome maintenance mechanisms critical for preventing age-related diseases by preserving stem and progenitor cell potential, but reports no new empirical findings.

This study identifies six novel keratin genes from the chromosome 17q21.2 region, suggesting their association with hair follicles, while all 27 keratin genes in the domain have been characterized transcriptionally.

This study found that people with alopecia who worry about not wearing a wig reported higher levels of depression, anxiety, and social anxiety, although wig use increased social confidence for many.

This study found that ectopic expression of Whn in transgenic mice caused impaired differentiation in epidermis and hair follicles, with hair growth defects and severe urinary tract issues leading to hydronephrosis.

In this study, three patients with extensive alopecia areata showed varying degrees of hair regrowth after 20 weeks of treatment with ustekinumab, a cytokine-targeting therapy.

This review discusses the role of the hedgehog signaling pathway in hematological cancers and its potential as a therapeutic target; it reports no new clinical findings.

This study found that in thin cutaneous melanomas, tumor regression is associated with a higher risk of sentinel lymph node involvement.

This study suggests that botanical 5AR inhibitors like Serenoa repens and β-sitosterol may improve symptoms of androgenetic alopecia, with 60% of treated subjects showing improvement compared to placebo.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

This review evaluates and classifies the non-saponin components of Korean Red Ginseng, emphasizing their combined role with saponins in the plant's bioactivity, but reports no new clinical results.

This review discusses the dual role of tissue-resident memory T cells in providing immune protection against infections and cancer and contributing to autoimmune skin disease pathology, without presenting new experimental results.

This review discusses phytotherapy options for managing benign prostatic hyperplasia, noting some herbal agents show promise in trials for mild-moderate symptoms but more evidence is needed for others.

This study found that the transcription factors Msx2 and Foxn1 are crucial for maintaining Notch1 expression in the hair follicle matrix, which is necessary for proper hair differentiation.

In this study, researchers found that electrospun membranes with aligned surface topography advanced the immune response towards an adaptive stage and highlighted the role of T cells in hair follicle regeneration in mice, showcasing the intricate interactions between immune and skin cells.

This review discusses melanocyte development, emphasizing the plasticity of melanoblasts and the role of both intrinsic and extracellular signals in their differentiation and migration, with no new clinical results reported.

These guidelines review the management of complications and specific forms of congenital ichthyosis and report no new results; they summarize expert and evidence-based recommendations for clinicians.

This review suggests that isotretinoin's effects on severe acne and various cancers may result from apoptosis, which might also explain its adverse effects through genetic variability.

This chapter reviews the role of androgen receptors in mediating the actions of androgens in specific tissues and provides no new experimental findings.

In this study, researchers reported that a keratinocyte growth factor-Ig fusion protein could specifically detect and localize KGFRs in epithelial tissues, suggesting a method for histochemical detection of growth factor receptors.
