3 citations
,
October 2022 in “Journal of Cosmetic Dermatology” This study found that alopecia areata patients had a higher serum CRP/albumin ratio compared to healthy controls, and this elevation was linked to disease severity, indicating its potential as an inflammatory marker.
2 citations
,
December 2021 in “Asian Journal of Beauty and Cosmetology” This study reported that a specific mixing ratio of Dendropanax extract and sea salt showed low cytotoxicity, high cell proliferation, anti-inflammatory, and antimicrobial effects, suggesting potential for functional cosmetics against hair loss.

October 2007 in “International journal of radiation oncology, biology, physics” This study observed that Gamma Knife radiosurgery is generally well tolerated, with some patients experiencing minimal acute complications like scalp numbness and fatigue, and most returning to work shortly after the procedure.
July 2026 in “International Journal of Clinical & Experimental Dermatology” This exploratory pilot study reported that using a 2% Oleosome-FGF-2 fusion extract scalp serum twice daily for 84 days in women with telogen effluvium and brittle hair improved hair density, anagen/telogen ratio, hair shaft thickness, and scalp hydration compared to a placebo.
May 2026 in “Malaysian Journal of Medicine and Health Sciences” This study found that in a testosterone-induced androgenetic alopecia mouse model, the combination of PRP-derived small extracellular vesicles and 5% minoxidil significantly improved hair follicle density and the anagen-to-telogen ratio compared to minoxidil alone, suggesting a synergistic effect that enhances hair growth.
December 2025 in “Anatomy (International Journal of Experimental and Clinical Anatomy)” In this study, researchers found that the congenital absence of the palmaris longus muscle was relatively uncommon and showed no significant differences according to sex, side, or digit ratio (2D:4D) among individuals assessed using MRI and radiographs.
July 2025 in “Journal of Dermatological Treatment” This study found that platelet-rich plasma significantly improved hair growth parameters in androgenic alopecia patients and was even more effective when combined with minoxidil, particularly in reducing vellus hair.
April 2025 in “Dermatology Practical & Conceptual” This study found that patients with alopecia areata had significantly higher systemic immune-inflammation index levels compared to healthy controls, regardless of the disease's severity.
January 2025 in “International Journal of Dermatology Research” This study found that patients with alopecia areata had a significantly higher mean platelet volume compared to healthy individuals, suggesting a potential link between hematological markers and the severity of the disease.
June 2024 in “Indian Journal of Plastic Surgery/Indian journal of plastic surgery” This study found that using a specific ratio method based on the patient's scalp measurements can effectively predict the dimensions of the permanent safe zone for hair transplants, particularly in early stages of androgenetic alopecia, potentially ensuring long-lasting transplant results.
November 2023 in “Biology” This study investigated 130 patients and found a significant inverse correlation between copper content and the copper/zinc ratio in hair samples and the extent of coronary artery disease, while zinc content alone showed no significant relationship with disease extent.
October 2023 in “Dermatology practical & conceptual” In this study, AMD was observed more frequently in AGA patients, and a higher monocyte/HDL ratio was associated with increased AMD severity, especially in men.
April 2020 in “Journal of the Endocrine Society” This study found that among transgender men undergoing long-term testosterone therapy, a severe pattern of androgenetic alopecia may indicate increased arterial stiffness, as measured by higher intima-media thickness of the carotid artery.
January 2020 in “the british journal of cardiology” This case report suggests that the progestogen-only pill may cause false-positive aldosterone/renin ratio results in primary hyperaldosteronism screening, indicating it should be omitted before testing.
March 2018 in “Benha Journal of Applied Sciences” This study found that while prolactin and DHEA-S levels were higher in women with hirsutism compared to controls, there was no significant correlation between second to fourth digit ratio and hormonal profiles.
April 2012 in “The Journal of Urology” In this prospective cohort study, male pattern baldness was identified as an independent predictor of prostate cancer, while the 2D:4D finger ratio was not associated with the cancer risk.
This research suggests that the digit ratio, 2D:4D, is unlikely to be a significant indicator of male androgenetic alopecia, contradicting a prominent isolated finding from a previous study.
11 citations
,
April 2015 in “International Journal of Cosmetic Science” This study found that topical adenosine significantly increased the ratio of thick hairs and contributed to global improvement in Japanese men with androgenetic alopecia compared to niacinamide, with no observed adverse events.
July 2022 in “International Journal of Health Sciences” This study assessed lipid parameters and serum DHT levels in type 2 diabetes patients, but the abstract does not specify the findings about their association.
