This study found that mixtures used in permanent hair dyes had irritant effects on reconstructed human epidermis, while individual ingredients alone did not.

This study identified a missense mutation in the keratin 71 gene as the cause of autosomal dominant woolly hair/hypotrichosis in a Japanese family, marking the first human mutation in KRT71 linked to a hair disorder.

This study found that isolated red light may serve as an alternative for photo-immunotherapy without additional photosensitizers, as it did not reduce keratinocyte differentiation markers or increase photo-oxidative damage, unlike treatment with IL-4 or UVA1/blue light.

Caspase-7 has functions in skin and hair that are not related to cell death.

This study found that the novel IPC analog SIG-1451 may inhibit inflammatory cytokine release in cell-based assays relevant to allergic dermatitis.

This study found that hypoxia-conditioned mesenchymal stem cell exosomes increased GM-CSF and decreased IL-1 expression in a dose-dependent manner in a murine model, suggesting potential for treating androgenetic alopecia.

In this study using mouse models, researchers found that elevated IL-17a in aged olfactory epithelium impairs olfactory function, while IL-17a inhibition promotes regeneration and mitigates age-related decline.

This study suggests that rather than inhibiting IL-15, selectively stimulating IL-15Ra-mediated signaling could be beneficial for managing alopecia areata and possibly other inflammatory hair loss conditions, as IL-15 promoted hair growth and maintained immune privilege in human hair follicles.

This study found that skin bacteria promote regeneration in wound-induced hair follicle neogenesis, suggesting a role for IL-1β signaling and challenging the belief that infection inhibits healing.

This study found that keratin-75, discovered in enamel tissue, is secreted by ameloblasts using an unconventional pathway involving the ER-Golgi-Intermediate-Compartment and Golgi, differing from typical cytokeratin localization.

In this study, researchers reported that IL-17C plays a key pro-inflammatory role in human skin diseases and may be a promising therapeutic target for inflammatory skin conditions.

This study found that combining metformin and clomifene citrate improved pregnancy outcomes and reduced miscarriage rates in women with PCOS and infertility undergoing intrauterine insemination.

This study found that genetic ablation of Tet genes in mice led to changes in hair structure and keratin gene expression, indicating a role for Tet-mediated 5hmC DNA oxidation in hair follicle development and cycling.

This study found that IL-9 influences the behavior of human primary keratinocytes by promoting motility while reducing invasion potential through a novel mechanism independent of matrix-metalloproteinases.

This study found that fisetin, a dietary flavonoid, significantly improved psoriasiform skin lesions in mice by promoting cell differentiation, inhibiting proliferation, and modulating inflammatory responses.

This study found that SM04755, a novel topical drug, inhibited inflammation, keratinocyte proliferation, and fibrosis in vitro and improved skin health in a mouse model of psoriasis, indicating potential as a topical psoriasis treatment.

This study found that retinoic acid and a retinol complex formulation showed different permeation and compound localization in a skin equivalent model, with unique lipid changes observed with only the retinol formulation.

This study on women aged 18–40 with polycystic ovary syndrome reported that a three-month treatment involving dietary changes, oral contraceptives, fertility drugs, and supplements significantly improved ovulation, menstrual regularity, BMI, and reduced hirsutism, acne, and certain immune factors compared to pre-treatment and control groups.

In this study, researchers found that TCDD exposure accelerated differentiation and altered gene expression in human epidermal cells, indicating the epidermal barrier as a target of TCDD-activated AHR.

This study found that the effectiveness of 17-beta-estradiol in inhibiting hair growth depends on its application method, and noted significant sex differences in response to 17-alpha-estradiol in male and female mice.

In this study, 7-phloroeckol, derived from marine brown algae, was found to promote hair growth by increasing cell proliferation and hair shaft elongation in cultured human hair follicles.

This study found that MENT is 10 times more potent than testosterone in suppressing gonadotropins and contributing to anabolism in monkeys, with a potentially wider therapeutic index for human androgen replacement and male contraception.

2011 dermatological research found new skin aging markers, hair loss causes, skin defense mechanisms, and potential for new treatments.

This study analyzed Neo-Assyrian medical texts from the first millennium BCE, revealing that treatments for women's hair, such as amulet use for hair thinning and loss, were categorized separately from women's reproductive health and generally included alongside men's remedies.

This study found that consuming sweetened tea drinks is associated with an increased risk of female androgenetic alopecia, and this relationship is influenced by bedtime habits rather than sugar intake from soft drinks.

This study found that frequent consumption of sweetened tea drinks is linked to a higher risk of female androgenetic alopecia, and this relationship is mediated by late bedtimes but not daily sugar intake.

This study used machine learning to identify molecular predictors of drug response in alopecia areata, suggesting a tool for predicting treatment efficacy based on gene signatures.

This study suggests that HDAC inhibitors, such as Vorinostat and Entinostat, could be effective in promoting hair regrowth in a mouse model of alopecia areata.

This study found that inhibiting JAK signaling can unexpectedly trigger hair growth in resting-phase mouse skin, implicating JAK-STAT pathways and oncostatin M in maintaining hair follicle stem cell quiescence.

This study suggests that dsRNA may enhance KRT9 expression in palm and sole skin through β-catenin signaling, potentially linking mechanical damage to specific skin features and certain skin conditions.
