April 2020 in “DOAJ (DOAJ: Directory of Open Access Journals)” This study established a mouse model of atopic dermatitis with overgrowth of Malassezia globosa using olive oil as a vehicle, which caused severe lesions and hair follicle damage.
This review discusses the potential effectiveness of certain essential oils in promoting hair growth for alopecia and reports no new clinical trials; the authors suggest these oils may increase hair thickness and volume.
January 2020 in “Journal of the Brazilian Chemical Society” This study suggests that using nanostructured lipid carriers may improve the targeting of 17-α-estradiol in treating alopecia by improving skin penetration and stability.
December 2019 in “Fayoum University Medical Journal” This study reported that prostaglandin D2 levels were significantly lower in both the serum and tissue of Egyptian patients with alopecia areata compared to healthy controls.
August 2019 in “Journal of archaeological science: Reports/Journal of archaeological science: reports” This study demonstrated that cortisol, estradiol, and testosterone are preserved in archaeological human hair, allowing for the analysis of ancient stress and reproductive hormone patterns.
August 2019 in “Archivos de medicina” This study observed a high prevalence of hair loss among students at the University of Manizales, Colombia, with significant associations found between hair loss and both academic programs and autoimmune diseases.
January 2019 in “ISGE series” This study found that estradiol and other sex steroids reduced the capture of monocytes by human endothelial cells in vitro, potentially inhibiting the formation of atherosclerosis by promoting nCAM polysialylation, which interferes with leukocyte tethering to the vascular endothelium.
May 2018 in “Más dermatología” In this study, among postmenopausal women with female androgenetic alopecia, the combination of Pygeum africanum and Serenoa repens extracts at higher doses plus MSM significantly increased total hair growth and hair resistance compared to a lower dose formulation after 16 weeks.
In this study, a clear pattern of selective sweep was observed for the SLC24A5 gene, with high linkage disequilibrium and low haplotype diversity, but no clear correlation with UV radiation intensity was found.
This study observed that a combination of two mineral and nutritional supplement products increased anagen-phase hair and reduced hair loss in women with androgenetic alopecia and acute or chronic telogen effluvium after four months.
August 2016 in “Annals of International medical and Dental Research” This study found that patients with alopecia had significantly higher mean serum ferritin levels compared to controls, except for those with telogen effluvium, whose levels were not significantly different.
This study observed that testosterone combined with hormonal contraceptives elevated hormones like estrone and testosterone, altered coagulation factors, and increased sexual behavior frequency in female capuchin monkeys.
April 2016 in “The FASEB Journal” This study found that blocking androgen receptors in male rats during the perinatal period led to permanently increased estrogen and ER-a expression in the hypothalamus, affecting sexual preference in adulthood.
January 2016 in “Surgical and Cosmetic Dermatology” This study showed that platelet-rich plasma treatment led to a statistically significant increase in terminal hairs and a reduction in vellus hairs in men with androgenetic alopecia.
December 2015 in “OPAL (Open@LaTrobe) (La Trobe University)” This study found that estrogen treatment induced premature catagen and apoptosis in hair follicles of wild-type mice, while having no effect on mice lacking estrogen receptor α.
December 2014 in “Bali Medical Journal” This study observed that estrogen receptor content was lower in white hair compared to black hair, with the lowest levels recorded in male white hair among participants aged 50-56.
This review discusses the potential of using sustained release systems to increase the effectiveness and reduce side effects of 17-alpha-estradiol in alopecia treatment and reports no clinical results.
January 2014 in “Journal of Changchun University of Traditional Chinese Medicine” This study found that resolving acne capsules may suppress acne keratosis and regulate hormone levels in a rabbit ear acne model, showing potential anti-acne effects.
August 2013 in “Fertility and Sterility” This in vitro study suggests that factors in the serum of PCOS patients may contribute to ovarian dysfunction, evidenced by higher hormone production and primordial follicle survival compared to control sera.
May 2013 in “UTUPub (University of Turku)” This study suggests that adding androgens to menopausal hormone therapy may reduce breast cancer risk by counteracting estrogen-driven proliferation in postmenopausal breast tissue.
December 2012 in “Journal of Dermatological Science” In this study, estradiol was found to increase VEGF expression in cultured dermal papilla cells at physiological levels similar to pregnancy, suggesting that declining estrogen might contribute to female pattern hair loss in older Japanese women.
August 2012 in “Open Repository and Bibliography (University of Liège)” This case report found that a dog's progressive alopecia and prostatitis were caused by ingesting a transdermal estradiol cream, emphasizing the need to identify exogenous estrogen sources during evaluation.
This study reported no significant difference in serum ferritin levels between female patients with telogen effluvium and those without hair loss.
January 2011 in “Junshi yixue” This study established a murine chronic graft-versus-host disease model with scleroderma features, showing typical skin changes and cellular infiltrates associated with the condition.
August 2009 in “International Journal of Dermatology” This case report describes a postmenopausal woman who experienced facial erythema, acne, and hirsutism due to excess androgen and estrogen levels.
January 2009 in “Anhui nongye kexue” This study found that higher concentrations of estradiol inhibited the growth of cashmere goat hair follicles, with associated morphological changes observed.
