In this review, researchers explored key mechanisms underlying androgenetic alopecia, revealing how hormonal, oxidative, inflammatory, and lipid dysregulation suppress hair growth pathways and suggesting new therapeutic targets such as DP2 antagonists and microbiome modulators.

This study found that increased levels of PGD2 and prostacyclin and decreased levels of PGE2 and PGF2α were associated with baldness in androgenetic alopecia, suggesting potential targets for treatment.

PGD2 stops hair growth and is higher in bald men with AGA.

This article reviews the pharmacology of bimatoprost and prostamide F2α, highlighting bimatoprost's therapeutic applications in glaucoma, hair growth, and potential fat reduction, without reporting new experimental results.

This review synthesizes knowledge on Prostaglandin E2's role in platelet biology and suggests that targeting PGE2 pathways could lead to personalized antiplatelet therapy without affecting hemostasis, but it presents no new results.

This study identified several compounds from traditional Chinese medicines that may inhibit prostaglandin D2 synthase, potentially providing promising candidates for treating androgenic alopecia with minimal adverse skin reactions.

This study found that low doses of bisphenol A may increase proliferation of the ventral prostate in adult rats by altering the estrogen to androgen ratio and gene expression.

This study identified a thiazolidine dione derivative as a potential inhibitor of 15-PGDH that may enhance prostaglandin activity in hair follicles, suggesting its use to support hair regrowth treatments.

This study suggests that the expression of the DP2 receptor is higher in balding scalp cells and that its knockdown could inhibit the transition to the catagen phase in cultured human hair follicles, potentially counteracting hair growth inhibition associated with male pattern baldness.

In this pilot study, topical latanoprost acid was observed to increase hair count and improve hair follicle structure in women with androgenetic alopecia, with no serious adverse events, suggesting potential for further investigation to confirm its efficacy and safety.

This study assessed Ageratum conyzoides gel's efficacy in reducing hair loss and improving quality of life in adults with pattern baldness, finding that it decreased temporal recession and improved hair-related distress scores, with a significant reduction in 5α-reductase expression and PGD2 release in vitro.

This review explores the role of fatty acids and bioactive lipid mediators in skin health and suggests targeting this metabolic network to control inflammation and improve skin conditions, but it reports no new findings.

This review explores the current treatments for different types of alopecia, emphasizing the need for well-designed clinical trials and highlighting that most therapies are used off-label, as only androgenetic alopecia has FDA-approved drugs.

A substance called prostaglandin D2 is linked to stopping hair growth in men with common baldness.

Early exposure to germs may protect against autoimmune diseases, lack of sex increases alcohol preference in fruit flies, a potential baldness treatment could involve blocking a specific receptor, skin memory cells help prevent re-infection, high-fat diets can affect brain cells related to weight, and the link between social status, stress, and heart disease in primates is unclear.

This review by St. Denis et al. highlights that prostaglandin E2 is overexpressed in several skin cancers and suggests targeting its pathway could offer potential treatments for these malignancies.

This review discusses the roles of prostaglandins in hair loss and highlights their potential as targets for new alopecia treatments, but reports no new clinical findings.

This review explores how adult skin epithelia preserve stem cell populations for hair follicle regeneration and wound healing, but reports no new experimental results.

This article reviews the mechanisms by which minoxidil stimulates hair growth and reports no new clinical findings.

This review discusses the role of signaling networks in sebaceous gland development and disorders, highlighting recent insights from mouse models and cell line studies, but reports no new experimental results.

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 review discusses how macro-environmental factors such as intradermal adipose tissue and sex hormones influence hair and feather stem cell niches, suggesting environmental targets for regenerative medicine, but reports no new clinical results.

This article reviews emerging treatments for androgenetic alopecia, including topical 5-alpha-reductase inhibitors and prostaglandin modulators, but reports no clinical results and calls for further efficacy evidence, especially for PRP.

This article reviews mechanisms by which herbal ingredients may stimulate or inhibit hair growth, and it reports no new clinical findings while suggesting potential for developing hair loss treatments.

This article discusses the need for rational strategies in developing hair loss drugs targeting specific events in hair follicle cycling, reporting no clinical findings but emphasizing the importance of understanding molecular controls.

This paper discusses mechanisms by which various chemicals disrupt male sexual differentiation, concluding that mixture risk assessments should include a broader set of compounds beyond phthalates to address cumulative reproductive health risks.

This study found that EP 2 signaling is crucial for macrophage recruitment and inflammatory regulation in the injured heart, impacting cardiac repair processes.

This study found that Wnt3a increased beta-catenin signaling and upregulated specific genes in cultured human dermal papilla cells, enhancing their response to PGE2 and potentially aiding hair growth.

This review discusses emerging targets for developing drugs to treat hair loss and reports no new clinical results; the authors emphasize the potential for therapies that regenerate hair follicles.

This study reports that polyphenols from Annurca apples may safely promote hair growth and protect against chemotherapy-induced alopecia without interfering with chemotherapy regimens.
