This study identified 65 bacterial species from human hair with varying carbon metabolic capabilities and proposed a systematic way to evaluate their ease of isolation under different conditions.

In this study, researchers formulated a herbal shampoo using traditional ayurvedic herbs and reported that it may serve as a natural and effective alternative to synthetic shampoos for cleaning and managing hair, emphasizing the growing preference for herbal products over chemical ones.

This study found that terpene compound concentrations in coniferous tree leaves were generally highest in spring and summer, suggesting these seasons are most effective for extracting essential oils.

This research highlights selenium's critical roles in various biological processes and underscores the potential health impacts of both its deficiency and excess, including increased mortality risk, poor immune function, and neurological issues.

This study found that peripilar signs on the scalp are linked to perifollicular lymphocytic infiltrates in early androgenetic alopecia, detectable even in areas with high hair density.

This review discusses mammalian models of epimorphic regeneration to define a vertebrate regeneration blastema, concluding that regenerative failure likely stems from cellular responses to the microenvironment after injury, not progenitor cell availability, and calls for targeted modification studies in mammals to advance human regeneration.

COVID-19 may cause a temporary hair loss condition called telogen effluvium in some patients after recovery.

This study found enhanced remyelination in the corpus callosum of late pregnant rats compared to virgin and postpartum rats, suggesting a pregnancy-associated promyelinating effect mediated, in part, by the GABA A receptor system.

This study found that carvone, a plant-derived compound, decreases melanin content and inhibits melanoma cell proliferation through the cAMP pathway, suggesting potential benefits for treating melanomas and other hyperpigmentation disorders.

In this study, a standardized 7.5% herbal extract significantly increased hair growth in men with androgenetic alopecia compared to a placebo over a 48-week period.

This study found that among 17 beta-(N-ureylene-N,N'-disubstituted)-4-azasteroids, those with an N'-phenyl moiety were the most effective inhibitors of human type I 5 alpha-reductase.

This study found that IL-4 VNTR intron 3 and TNF-α (rs1799964) gene polymorphisms do not have a significant association with alopecia areata susceptibility in the Egyptian population.

This abstract discusses Netherton Syndrome, a genetic disorder with a characteristic triad of symptoms caused by SPINK5 gene mutation, and reports no new clinical findings or treatment advances.

This review discusses scaffold materials and properties used in epidermal tissue engineering to promote skin regeneration and reports no new research findings.

This article reviews the clinical presentation and histopathologic features of alopecia areata and proposes a hypothesis for its development, but it reports no new clinical results.

This review discusses the classification and diagnosis of pregnancy-related skin conditions and reports no new clinical findings.

This article outlines manifestations of systemic lupus erythematosus, noting rapid joint symptom improvement with corticosteroids and antimalarial drug responsiveness for skin symptoms, and links anti-Ro with photosensitive rash and subacute lupus.

This study found that prenatal exposure to finasteride in rats led to permanent changes in developmental endpoints like anogenital distance and nipple retention, which were predictive of further reproductive tract malformations.

This review discusses the role of 5α-reductase enzymes in androgen action and related disorders, noting that their specific inhibitory drugs show promise for conditions like benign prostatic hypertrophy; it reports no new clinical results.

This review examines how mesenchymal stem cells and their derivatives may enhance skin regeneration and rejuvenation, but it reports no new clinical results; the authors suggest iPSC-derived MSCs hold promise for future therapies.

This study discovered nine human type I hair keratin genes, including a transcribed pseudogene, in a 190 kbp genomic region, revealing three gene subclusters based on sequence homologies.

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.

More research is needed to understand alopecia areata severity.

This study suggests that chemotherapy-induced anagen effluvium represents patterned hair loss, with most patients retaining hairlines, but patterns do not vary significantly by age, symptoms, or chemotherapy type.

This study revealed that deficiency in the enzyme FA2H in mice affected sebaceous gland function, altered sebum composition, and caused cycling alopecia, highlighting FA2H's role in hair follicle homeostasis.

This study found that GLI2 plays a key role in activating follistatin, an activin/BMP antagonist, in response to hedgehog signaling in human epidermal cells, with implications for hair follicle development and basal cell carcinoma.

Minoxidil affects collagen-related genes, potentially helping treat fibrosis.

This study found that mange-infected bare-nosed wombats have increased heat loss, higher metabolic rates, altered behavior, and disrupted fatty acid composition compared to healthy individuals.

In this study, Gaussian process regression models combined with Grey Wolf optimization were used to predict and optimize phenolic and flavonoid content extraction from Carthamus caeruleus L. rhizomes, showing high accuracy and helping improve understanding and extraction processes through a new interactive tool.

This study found that 3D cultured hair follicle-like constructs, which include keratinocytes and dermal papilla cells, showed improved gene expression and cell interactions relevant to hair follicle development.
