This study in identical twin males with androgenetic alopecia found that dutasteride significantly improved hair growth compared to placebo over one year.

This study found that a genetic model using SNPs can predict early-onset male-pattern baldness with moderate accuracy, which may assist in decisions about interventions.

This article updates Japanese guidelines for diagnosing and treating male and female-pattern hair loss, recommending specific drugs and therapies while advising against certain treatments for female-pattern hair loss.

This study found that medroxyprogesterone acetate treatment in women with PCOS reduced hyperandrogenism-related hormonal levels and improved skin conditions without affecting lipid or carbohydrate metabolism.

In this study, Norwegian men aged 20-50 who perceived themselves as having more hair loss reported greater dissatisfaction and concern about aging compared to those without hair loss.

This study found that 4-MA is a potent inhibitor of testosterone 5α-reductase in human tissues, promising potential for treating androgen-dependent skin conditions like male pattern baldness.

This review discusses the emerging roles of transit-amplifying cells in tissue regeneration and cancer formation, highlighting their significance beyond a mere transitional state in hair follicles and the hematopoietic system.

This review examined studies on erectile dysfunction and 5 alpha-reductase inhibitors, concluding that these drugs do not significantly cause erectile dysfunction and emphasizing testosterone's importance over dihydrotestosterone in erectile function.

This study found that using hair steroid profiling, dutasteride treatment led to reduced dihydrotestosterone levels and DHT/testosterone ratio in patients with male-pattern baldness.

This study found that four microRNAs, which were significantly upregulated in balding hair follicle papilla cells, could play a role in the development of male pattern baldness.

This study found that early-onset male pattern baldness was associated with a reduced relative risk of prostate cancer.

This review examines the roles of testosterone, dihydrotestosterone, and estradiol in activating male sexual behavior in laboratory animals and humans, reporting no new clinical results.

This study introduces the multiple papillary centres model, offering a new explanation for hair twisting by combining known hair morphology features with differential growth rates caused by dermal papillae.

This study reports that the prevalence of male pattern baldness in Asians is higher than previously believed, with potential links to socioeconomic factors and westernized diets, though the exact cause remains unclear.

This study found that combining fractional radiofrequency microneedling with 5% topical minoxidil improved hair count and thickness more than minoxidil alone in Chinese men with male pattern hair loss.

This study found that nutritional deficiencies, particularly in amino acids and certain micronutrients, are common in individuals with hair loss across all types of alopecia.

This study found that finasteride decreases DHT/T levels more significantly in the vertex scalp hair than in the occipital hair of patients with male pattern baldness.

This study shows that multiphoton microscopy can non-invasively distinguish between scarring and non-scarring alopecia by identifying certain morphological features, but further research is needed to confirm its clinical utility.

This study found that an oral marine protein supplement significantly increased hair growth and reduced hair shedding in women with temporary thinning hair over 90 days compared to a placebo.

This study found that loss of contact between the arrector pili muscle and the hair follicle bulge may explain why hair loss in male and female pattern baldness is largely irreversible, unlike in alopecia areata.

This study found that scanning electron microscopy revealed considerable abnormalities in hair morphology in MPS I, II, IIIA, and IIIB patients, potentially related to heparan sulfate accumulation.

In this study, men seeking treatment for male pattern hair loss were highly concerned about their condition and had often attempted self-treatment, but many were dissatisfied with their physician consultations due to unmet expectations and perceived indifference from doctors.

This study introduced a new classification method for male pattern baldness in Korean men, detailing six types that could guide hair restoration surgery and further research.

This study found that the cocrystal of mycophenolic acid with isonicotinamide significantly improved solubility and dissolution rate, while two other cocrystals showed decreased performance in these areas.

This study concluded that platelet-rich plasma injections significantly improved hair density, thickness, and scalp inflammation in both male and female pattern hair loss, with better outcomes in lower-grade cases.

This study observed that mast cells and increased collagen and elastic fibers in the scalp may contribute to male pattern hair loss, but additional research is needed for further understanding.

This review discusses the perceptions of male pattern baldness by strangers and explores the sociocultural aspects of hair and hair loss but reports no new results.

In this study, male-pattern baldness was strongly associated with a higher risk of keratinocyte cancers, particularly squamous cell carcinoma and melanoma, likely due to increased sun exposure on the scalp rather than androgen levels.

This review summarizes recent research on the molecular properties and functions of L-PGDS and PGD2, but reports no new findings, highlighting their pathophysiological roles and guiding future studies.

This study suggests that any baldness, particularly moderate balding, is associated with a higher risk of fatal prostate cancer in men, supporting a possible link between hair loss and prostate cancer mechanisms.
