In this mouse study, researchers found that dermal Wnt signaling/β-catenin activity is essential for fibroblast proliferation and initiating hair follicle formation by interacting with epidermal Wnt ligands.

This review discusses the use of antiandrogens like flutamide and its derivatives in prostate cancer treatment and highlights the need for next-generation antiandrogens for improved efficacy; it reports no new clinical results.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This review discusses recent advances in understanding gender differences in skin and their implications for dermatologic diseases, but it reports no new experimental results; ongoing research is necessary for translating these insights into clinical practice.

This review concluded that oral finasteride for men and topical minoxidil for both genders have the most evidence supporting their effectiveness and safety for treating androgenetic alopecia.

This review explores finasteride's effects on neuroactive steroid levels and their potential influence on disorders like depression and alcohol withdrawal but reports no new clinical findings.

This study observed that autologous platelet-rich plasma treatment improved hair count and density in areas with androgenetic alopecia compared to placebo, with differing outcomes based on the PRP collection device used.

This review provides a comprehensive guide to serum-free human hair follicle organ culture methods, highlighting research opportunities, standardization efforts, and potential applications without reporting new empirical findings.

This article discusses the evaluation and management of a 45-year-old woman with diffuse scalp-hair loss and reports no new clinical findings.

This study found that feather patterning is primarily self-organizing and dynamic, relying on both genetic and epigenetic controls, with implications for similar processes like fingerprints and pigmentation.

Minoxidil is the only FDA-approved topical drug for treating male or female pattern hair loss, and other medications like finasteride and dutasteride can also increase hair growth.

This pilot study suggests injecting platelet-derived growth factors into the scalp may offer some clinical benefits for androgenetic alopecia, though further randomized trials are needed for confirmation.

This article discusses treatment options for androgenetic alopecia, noting that medical interventions like finasteride and minoxidil can halt and partially reverse hair loss in mild to moderate cases, especially when combined with surgery.

This review highlights the challenges in identifying histological features of adverse reactions to soft tissue fillers and emphasizes the need for increased awareness due to product uncertainty and delayed reactions.

This review found that microneedling appears to be a safe and effective option for treating scars and wrinkles, with fewer side effects and shorter recovery time than some other treatments.

This article outlines the clinical features, evaluation, and treatment strategies for androgen excess in polycystic ovary syndrome, highlighting important diagnostic and management approaches but reporting no new research results.

This review discusses niosomes' increasing popularity in dermatology for topical drug delivery due to their ability to enhance drug penetration, provide sustained release, and carry various drugs, while reporting no new clinical findings.

This review discusses the potential role of steroid 5α-reductase inhibitors in treating neuropsychiatric disorders related to dopaminergic hyperreactivity but reports no new clinical results.

This review discusses recent advances in trichoscopy for differentiating types of alopecia and presents a systematic approach for using its diagnostic findings, but reports no new clinical results.

This review discusses diagnostic approaches for women with diffuse, nonscarring hair loss and reports no new clinical results.

This review concluded that FDA-cleared low-level laser therapy devices are safe and effective for patients with male and female pattern hair loss who do not respond to or tolerate standard treatments.

This study concluded that 5α-reductase inhibitors were linked to increased sexual dysfunction in men with benign prostatic hyperplasia, but not in men with androgenetic alopecia.

This review discusses the role of androgens in women's skin-related conditions like acne, hirsutism, and female pattern hair loss, noting the lack of dermatology guidelines for when to pursue endocrinologic evaluation.

This study observed that in frizzled 6 null mice, initially uncorrelated hair follicle orientations develop into highly ordered patterns over time, suggesting possible mechanisms for biological structure patterning.

This study found that finasteride decreased plasma dihydrotestosterone levels and altered steroid metabolism, similar to the profile of male pseudohermaphrodites with inherited 5a-reductase deficiency.

This review discusses possible medication-induced hair loss and the need to exclude other confounding factors like stress and illness; it reports no new clinical findings and emphasizes careful assessment before attributing hair loss to medications.

This review discusses common skin appendage diseases, including their pathophysiology and treatments, but does not report new results.

This review discusses various techniques for evaluating hair shedding and alopecia but reports no new clinical results. The authors emphasize the value of specific clinical and instrumental methods in assessing hair growth.

This review discusses dermal white adipose tissue's roles in skin immunity, highlighting its antimicrobial function and interactions with other immune cells, but reports no new clinical results.

This review discusses treatment options for female pattern hair loss, emphasizing the importance of early intervention and the benefits of combined therapies, but reports no new clinical results.
