August 2026 in “DOAJ (DOAJ: Directory of Open Access Journals)” In this study, no significant association between androgenetic alopecia and increased blood pressure or serum aldosterone levels was observed among a small sample of Saudi Arabian men.
July 2026 in “International Journal of Science and Research (IJSR)” In this study, women with PCOS were found to have higher BMI, insulin resistance, and homocysteine levels, which are key predictors of the condition.
June 2026 in “Biomolecules and Biomedicine” This study found that women with PCOS had higher levels of serum phoenixin isoforms, which correlated with reproductive and metabolic markers, suggesting these isoforms may have a potential diagnostic role.
May 2026 in “Archives of Dermatological Research” In this study, serum levels of vitamin C, vitamin E, and total antioxidant capacity did not differ significantly between individuals with premature greying hair and controls, but a strong association with family history was observed.
May 2026 in “Electronic Journal of General Medicine” In this study, researchers found that women with PCOS and insulin resistance had higher irisin levels, while both PCOS groups had lower betatrophin levels compared to controls. These distinct biomarker alterations could aid in better metabolic profiling and risk assessment for PCOS.
April 2026 in “Global Journal of Health Science” This study observed that patients with hypothyroidism-associated hair loss commonly have deficiencies in several vitamins and minerals, suggesting that these deficiencies may be linked to their condition.
March 2026 in “Skin Appendage Disorders” This study reviewed multiple research articles and found that patients with telogen effluvium, primarily women, had significantly lower levels of serum ferritin and vitamin D compared to healthy controls, suggesting a role for trace element imbalances in hair loss.
This systematic review and meta-analysis found that patients with telogen effluvium, primarily females, exhibited significantly lower serum levels of ferritin and vitamin D compared to healthy controls, suggesting trace element imbalances play a crucial role in this type of hair loss.
This study found that telogen effluvium is strongly linked to lower serum levels of ferritin and vitamin D, especially in predominantly female patients.
March 2026 in “Dermatology Reports” In Indonesian men with early androgenetic alopecia, this study found that hair iron levels were positively correlated with hair diameter, suggesting potential for improving hair thickness.
January 2026 in “International Journal of Pharmaceutical Quality Assurance” In this study, researchers observed that patients with Alopecia Areata had significantly lower serum zinc and higher copper levels compared to healthy controls, indicating a disrupted zinc-copper balance that may contribute to the disease's pathogenesis.
This study found a significant association between lower vitamin D levels and increased severity of androgenetic alopecia in men.
January 2026 in “Mansoura Medical Journal” This study found that patients with Telogen Effluvium had significantly higher levels of scalp pain and itching, and serum ferritin levels could effectively differentiate them from healthy controls.
December 2025 in “Cureus” This study found that women with telogen effluvium had significantly lower serum ferritin levels compared to healthy controls, suggesting an association between iron deficiency and this form of hair loss.
December 2025 in “Frontiers in Nutrition” This study found that in patients with AIDS-related non-Hodgkin lymphoma undergoing targeted therapy, a positive serum albumin change rate was significantly associated with better treatment outcomes, suggesting the value of dynamic albumin monitoring and nutritional support during treatment.
December 2025 in “Obesity Surgery” In this study, researchers found that patients undergoing one-anastomosis gastric bypass experienced a greater incidence of low serum zinc levels and related symptoms, such as hair loss and delayed wound healing, compared to those undergoing sleeve gastrectomy.
November 2025 in “Open Access CRIS of the University of Bern” This study compared serum and hair steroid hormone profiles in adolescents and found that hair steroid profiling is a feasible, non-invasive alternative to serum analysis, with androgen levels in both mediums correlating more strongly with body size and composition in boys than in girls.
November 2025 in “European Journal of Endocrinology” This study found that hair steroid profiling is a feasible, non-invasive alternative to serum analysis in adolescents, with androgen levels correlating more strongly with body size and composition in boys than girls.
November 2025 in “Fayoum University Medical Journal/Fayoum University Medical Journal ” This study found that intralesional vitamin D3 injections significantly increased serum vitamin D3 levels in patients with localized alopecia areata, although baseline vitamin D3 levels did not predict disease severity or treatment response.
This study found that serum irisin levels were significantly lower in patients with androgenetic alopecia compared to healthy controls, but no significant relationship was detected between serum irisin levels and insulin resistance markers like BMI, fasting insulin, or HOMA-IR.
October 2025 in “Pakistan Journal of Health Sciences” This study found that low serum ferritin levels were significantly associated with non-scarring alopecia in women from Punjab, Pakistan, suggesting that assessing ferritin could help identify iron deficiency as a modifiable factor in hair loss.
October 2025 in “Nepal Journal of Dermatology Venereology & Leprology” This study conducted at Tribhuvan University Teaching Hospital found no significant correlation between serum testosterone levels and acne severity in adult female patients with acne, suggesting that serum testosterone is not a reliable marker of androgen excess in this sub-population.
