This study found that, in female patients with idiopathic telogen effluvium, a supplement containing zinc, biotin, and other nutrients significantly improved hair loss and quality over 180 days, whereas another supplement with different ingredients had less consistent effects.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

This study found that integrin-linked kinase is crucial for various epidermal functions, including differentiation and barrier formation, and also plays a previously unreported role in melanocyte development and function.

In this study, Hispanic individuals in Northern Nevada were found to be disproportionately affected by COVID-19, although they had lower mortality rates compared to their non-Hispanic counterparts.

This study reported that exogenous R-spondin-1 can restore hair follicle neogenesis in adult mouse cells, highlighting differences in gene expression and signaling pathways between fetal and adult dermal papilla cells.

This study found that a single application of 'Lye' or 'No-Lye' chemical straighteners significantly reduced drug concentrations in hair samples from both drug-fortified standards and authentic drug users.

This review compares the CO2 and Er:YAG laser treatments for acne scars, noting that while CO2 lasers offer deeper tissue penetration for severe scars, Er:YAG lasers pose a lower risk of post-inflammatory hyperpigmentation, and recommends personalizing treatments and considering combination therapies.

This study found that the retinoid receptor and PPAR pathway are involved in hair follicle miniaturization in androgenetic alopecia, alongside androgen receptors.

This study found that the uptake of molecules by hair is influenced by both hydrophobic and ionic charge interactions, with binding affinity decreasing as pH approaches the solute's dissociation constant.

This article discusses how nutritional and environmental factors, along with antioxidant supplementation, may improve hair growth by mitigating the effects of androgens and reports no new clinical results.

This study used numerical models to explore the cooling power required by different scalp cooling devices to prevent chemotherapy-induced hair loss, finding that coolant temperature significantly influences scalp tissue temperatures.

This study found that mice lacking CD61 had significantly shorter lower incisors compared to wild-type mice, suggesting CD61 is crucial for proper tooth growth and pre-ameloblast proliferation.

This study found that adjusting plant growth conditions, such as the use of elicitors like yeast extract and methyl jasmonate, increased wedelolactone production in Eclipta alba cell suspension culture.

This paper highlights the growing scientific interest in plant extracts for cosmetics due to their potential benefits, including antioxidant, antimicrobial, and protective properties, while emphasizing the need for quality and safety assessment to mitigate possible adverse reactions.

This review discusses molecular signaling pathways and nutritional factors influencing feather growth and regeneration in poultry and offers no new results; the authors suggest these insights may guide strategies for producing superior plumage.

This study developed mathematical models showing that heat penetrates individual hair quickly but takes longer to reach the center of hair bundles, helping understand potential damage from high-temperature styling tools.

This study suggests that hydroxypinacolone retinoate (HPR) may be an effective alternative to tretinoin for anti-aging skin treatments, offering similar collagen production benefits without increased skin irritation.

This meta-analysis reported that finasteride 1 mg/day significantly increased hair count in male androgenetic alopecia compared to placebo, but highlighted persistent sexual side effects and associated depression risk.

Finasteride treats hair loss but may affect prostate cancer detection.

This study found that the circular RNA circCOL1A1 influences the formation of superior-quality brush hair in white goats by regulating hair follicle stem cell behavior and interacting with the miR-149-5p/CMTM3/AR axis.

In this study, beta-caryophyllene enhanced wound healing in female mice by improving re-epithelialization, cell proliferation, and cell migration, suggesting potential benefits of essential oil compounds in inflammation reduction.

This study observed that Wnt5a mRNA expression in mice correlates with the hair cycle and inhibits hair follicle growth by antagonizing the Wnts pathway.

This study investigated single-cell changes in photoaged skin, revealing distinct cell clusters and increased activity in PD-L1 and PD-1 pathways in sun-exposed areas, enhancing understanding of UVA-induced skin damage and potential prevention targets for photoaging and UV-induced skin cancers.

This review discusses methods for improving study design and evaluation in sexual health literature and reports no new clinical results; it highlights current methodological issues and the benefits of validated questionnaires.

This study observed that men with frontal and moderate vertex baldness between ages 40 and 50 had a higher risk of aggressive prostate cancer, suggesting a potential link between baldness pattern and cancer risk.

Dermatologists greatly affect inpatient diagnosis and treatment of skin conditions, especially in spotting infections in patients with weakened immune systems.

This letter to the editor addresses corrections related to an earlier study on the effect of the dual 5α-reductase inhibitor dutasteride on markers of tumor regression in prostate cancer, but reports no new findings.

This review discusses the role of androgens in male sexual differentiation and characteristics and reports no new clinical results; it emphasizes the androgen dependence of male pattern scalp hair loss.

This study found that plantar dermis matrix homogenate can partially restore the regenerative capacity of hair follicles impaired in culture, with CTHRC1 playing a critical role in this process.
