This study found that despite carrying an activating Hras mutation, hair follicle stem cells integrate into normal skin without causing tumors, unlike similar mutations in the epidermis, suggesting unique tumor-suppressing mechanisms in hair follicles.

This study found that mackerel-derived fermented fish oil extract and its component DHA promote hair growth by activating anagen pathways in dermal papilla cells.

This study suggests that Platycarya strobilacea extract promotes hair growth in mice by enhancing stem cell factor expression, reducing mast cell numbers, and increasing cytokines associated with hair growth.

This review discusses the role of hair follicle bacterial colonization in immune responses and the pathogenesis of alopecia but reports no new clinical results.

This study reported that the pseudoceramide bis-oleamido isopropyl alcohol (BOI) promotes hair growth in ex vivo cultured human hair follicles, likely by enhancing sphingolipid synthesis in dermal papilla cells.

This study found that in C57BL/6 mice, treatment with fermented red ginseng marc, a traditional polyherb formula, or a combination of both, promoted hair growth by enhancing the hair-growth cycle.

This review discusses commonly used dietary supplements for hair growth and highlights the lack of evidence supporting their efficacy and safety in the absence of nutritional deficiency; it reports no new research results.

In this study, curcumin-loaded nanoparticles with a size of 400 nm showed optimal accumulation in human hair follicles after seven days, although mouse models differed significantly in penetration and retention, indicating limitations in their suitability for follicular drug delivery studies.

This study developed a mathematical model to explore the interactions between hair cycle dynamics and immune system activity in alopecia areata, providing insights into disease progression and potential targets for treatment by simulating immune response effects on hair follicles.

This review discusses advancements in regenerative medicine for hair loss treatments, highlighting stem cell techniques for rejuvenating or creating hair follicles, but provides no new clinical results.

This article discusses conventional and alternative treatments for hair loss but presents no new findings, highlighting concerns about the unknown long-term effects of approved drugs.

This study found that treatment with PTH-CBD stimulated hair growth in mice with alopecia areata, with increased levels of beta catenin indicating activation of the Wnt pathway.

This study found that a mixture of Red-BCQ and Agnex extract promoted greater hair growth and antioxidant effects in C57BL/6 mice compared to other groups, including minoxidil treatment.

This study found that applying TPA to mice accelerated hair follicle regeneration by activating Akt and Wnt/ß-catenin signaling pathways, involving hair follicle stem cell proliferation.

This study found that Gsdma3 mutation in mice allows hair follicles to bypass a typical telogen phase and directly enter the anagen phase, suggesting Gsdma3's role in hair cycle transitions by regulating Wnt signaling.

This study indicates that targeting the PTH/PTHrP receptor may potentially stimulate hair growth, particularly for chemotherapy-induced alopecia, as observed in hairless and cyclophosphamide-treated mice.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

This review examines the role of stem cells and their niches in continuously growing ectodermal organs like teeth, hair, and claws, providing insights from mouse models without presenting new research findings.

This study found that mutations in the Sgk3 gene cause defective hair follicle development and altered hair cycling in mice, with variable phenotypic outcomes depending on different dysfunction patterns of the SGK3 protein.

This article reviews common hair loss disorders, emphasizing their potential links to systemic disease and the importance of thorough diagnostic evaluation, but reports no new clinical results.

This review discusses the adverse effects on hair associated with targeted cancer therapies and reports no new clinical results; it emphasizes the need for comprehensive documentation of these effects.

This study found that low fluence photoepilation with intense pulsed light targets the pigmented area of hair follicles, causing temporary hair loss by inducing a catagen-like state without severe follicle damage.

This study observed that Aconiti Ciliare Tuber extract may promote hair growth in mice by activating the Wnt/β-catenin signaling pathway.

This animal study found that dermal papilla cells in hair follicles of chimeric mice can originate from various fibroblasts in the skin, challenging assumptions about their specific lineage.

This review discusses the clinical, epidemiological, and pathophysiological aspects of female pattern hair loss, reporting no new research findings.

This article discusses treatments for female pattern hair loss, highlighting that oral antiandrogens and topical minoxidil can effectively arrest progression and reverse miniaturization in many patients with mild-to-moderate cases, but it reports no new clinical results.

This article reviews current knowledge on the causes, diagnosis, and medical treatments for androgenetic alopecia, particularly in men, and reports no new findings.

This review discusses the combination of laser hair removal and topical eflornithine for managing resistant hirsutism, providing guidance based on existing clinical data, but reports no new results.
