This study found that acute stress can cause rapid hair loss by triggering necrosis in hair follicle cells and initiating autoimmunity, revealing a mechanism where stress-induced nerve activity leads to tissue damage and immune system activation.
November 2025 in “Scientia Pharmaceutica” This review highlights that injectable biostimulatory agents like poly-L-lactic acid, polycaprolactone, and calcium hydroxyapatite are effective in regenerative aesthetics by enhancing collagen production, stimulating adipogenesis, and improving dermal quality, although further research is needed to standardize protocols and confirm long-term safety and efficacy.
November 2025 in “Contact Dermatitis” This study reported a case of acute kidney injury and toxic contact dermatitis in a 25-year-old woman following exposure to a glyoxylic acid-containing hair straightening product, highlighting glyoxylic acid's potential role in cutaneous and renal complications and underscoring the need for stronger regulation and awareness.
November 2025 in “Zenodo (CERN European Organization for Nuclear Research)” In this study, researchers evaluated hair loss in 40 participants and identified key Ayurvedic and biochemical factors, finding frequent dietary incompatibilities and a high prevalence of low serum calcium, supporting an integrated approach emphasizing diet and scalp health.
November 2025 in “Zenodo (CERN European Organization for Nuclear Research)” In this study, low serum calcium and dietary incompatibilities were linked to hair loss, supporting Ayurveda's connection between Asthi Dhatu and hair, and suggesting an integrative approach for prevention.
In this chapter, the authors explore hyperdiluted CaHA as a new potential treatment for mild to moderate hair loss, providing preliminary insights into its application as an innovative option within regenerative therapies.
October 2025 in “Nephrology Dialysis Transplantation” In this case report, a young woman experienced acute kidney injury linked to the use of a hair straightening product containing glyoxylic acid, suggesting dermal absorption may lead to calcium oxalate nephropathy; this highlights the need for regulatory review and public health intervention.
August 2025 in “Clinical Toxicology” This study suggests an association between glyoxylic acid-containing hair-straightening treatments and acute kidney injury in young women, with urine calcium oxalate crystals observed in some cases, indicating potential nephrotoxicity. Early treatment with thiamine and pyridoxine may mitigate the severity of kidney damage.
