July 2025 in “Clinical and Experimental Dermatology” In a case report, complete hair regrowth was observed in a patient with severe alopecia areata after treatment with deucravacitinib, a TYK2 inhibitor, suggesting new therapeutic avenues for alopecia areata despite TYK2 not being traditionally linked to this condition.
In this study, women in their 40s with hair loss showed significant improvements in hair properties such as pore density and hair thickness when treated with a caffeine-based scalp ampoule and Microneedle Therapy System, compared to a caffeine-free control.
January 2026 in “Clinical and Experimental Dermatology” In this case report, complete hair regrowth was observed in a patient with autoimmune-related alopecia areata after treatment with a Janus kinase inhibitor, suggesting its potential effectiveness for both genetic and sporadic forms of the condition.
March 2025 in “Digital Library of Theses and Dissertations (Universidade de São Paulo)” In this study, the researchers observed that ferulic acid and resveratrol effectively protected chemically treated hair from oxidative damage, particularly against protein loss and color degradation, but not cisteine oxydation prevention, and these antioxidants also offered protection against sun-induced damage when used in conditioners.
