This study identified that 80% of a rural population in Ecuador uses medicinal plants like Aloe vera for treating hair conditions, highlighting the prevalence of ancestral plant knowledge.

This study suggests that hair follicle dermal stem/progenitor cells play a key role in both hair regeneration and skin wound healing, with potential implications for preventing hair follicle miniaturization linked to aging or alopecia.

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.

This study found that a composition including Serenoa repens extract and anti-inflammatory agents effectively suppressed inflammation-related gene expression in a keratinocyte model, suggesting a potential dual strategy for treating androgenetic alopecia.

In this study, researchers using molecular docking techniques found that 12-Methoxy carnosic acid from rosemary shows promising potential as a natural inhibitor of the 5 alpha reductase enzyme, which is involved in hair loss, suggesting its efficacy compared to finasteride.

This study found that ingesting seeds from the Lecythis ollaria tree may cause hair loss and other toxic effects in animals.

This study identified Sciellin, a new protein precursor to the cornified envelope in keratinocytes, with unique solubility properties hinting at its potential role in envelope assembly.

In a mouse model, this study found that an ethanol-based rosemary extract speeds up wound healing and reduces scarring by activating the TRPA1 nociceptor in sensory neurons, with carnosic acid identified as a key component.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

This study found that ultrasonically depolymerized ι-carrageenan from Solieria chordalis yields low-molecular-weight fractions that maintain fibroblast viability and show no cytotoxicity, suggesting potential for safe use in human medicine.

This article reviews the identification and characterization of soluble proteins in horny tissues such as calluses and psoriatic scales, but reports no new clinical results.

In this study, researchers found that skin pigmentation alterations in a mouse model of Carney complex may be caused by specific dermal fibroblasts promoting melanogenic signaling.

In this study, the vitamin D analogues 1 alpha,25-dihydroxy-vitamin D3 and calcipotriol were found to thin the living cell layer and affect differentiation marker expression in organotypic cultures of human outer root sheath cells.

In this study, researchers tested lotions containing DGLA, S-equol, and propionyl-l-carnitine on individuals with androgenic alopecia, noting a significant increase in hair count for women and a marginal increase for men after 6 months, along with improved hair cycle dynamics.

In this study, sarolaner administered orally proved effective in treating demodectic mange in a naturally infested cat in Brazil, as no mites were observed and skin condition improved after 21 days.

This study found that the hydromethanolic extract of Carthamus caeruleus L. rhizome demonstrated significantly higher antioxidant and cytotoxic activities compared to the chloroformic extract, particularly against NCI-H460 lung carcinoma cells, suggesting its potential use as a traditional treatment for burns.

This study found that chondroitin sulfate levels were higher than hyaluronic acid in skin and hair follicle samples, with the highest concentration observed in prekeratin of hair follicles and wool fibers.

This study found that the petroleum ether extract of Solanum nigrum may promote hair regrowth in testosterone-induced hair loss in rats, as indicated by increased follicle density and anagen/telogen ratio.

This study found that mice deficient in ceramide synthase 4 showed altered sebum composition and progressive hair loss due to obstructed hair canals.

In this study, cinnamic acid in solution form showed strong antifungal activity against Microsporum canis, but when incorporated into hydrogels, the acid's diffusion and resulting antifungal performance decreased, though it maintained effectiveness for potential prolonged exposure.

This study found that the methanolic extract of Carthamus caeruleus roots significantly reduced inflammation, promoted wound healing, and enhanced hair growth in experimental models, supporting its traditional use in Northern Algeria as a skincare remedy.

In this study, a newly developed cardamonin-loaded liposomal formulation significantly enhanced hair growth and improved hair follicle performance in mice with androgenic alopecia.

In this study, all stereoisomers of cyoctol were synthesized and tested, revealing that contrary to initial patent claims, cyoctol does not function as an anti-androgen.

This study found that diphlorethohydroxycarmalol significantly increased prostaglandin $E_2$ synthesis in HaCaT human keratinocytes by upregulating COX-1 and COX-2 expression, suggesting potential benefits from elevated $PGE_2$ production.

This source provides supplementary materials for the Carnivore Follicular Integrity Framework, a theoretical model proposing that animal-based diets may support hair follicle stability through several biological mechanisms. The materials include definitions, nutrient tables, and mechanistic notes but do not report empirical results.

This study evaluated the stability of multiple active ingredients in TrichoSol™ for use in alopecia treatments, finding varying stability durations at room temperature—up to 180 days for some ingredients—supporting its use as a compounding vehicle in personalized therapies.

This study found that Carthamus tinctorius floret ethanolic extract stimulated melanogenesis in B16F10 murine melanoma cells without cytotoxicity, suggesting its potential as a treatment for gray hair.

In this study, researchers developed microcapsules and effervescent tablets containing policosanol from insect wax, achieving high encapsulation efficiency and rapid water dispersion, effectively addressing the challenges of solubility and psychological acceptance in consuming insect-based lipids.

This review discusses the cornification process of epidermal keratinocytes in forming the skin barrier and reports no new results; it emphasizes the importance for diagnosis and treatment of skin disorders.
