August 2024 in “Journal of Cosmetic and Laser Therapy” This study found that intralesional vitamin D3 achieved similar effectiveness to triamcinolone acetonide for treating patchy alopecia areata but was associated with fewer adverse effects and higher patient satisfaction.
July 2026 in “Journal of Investigative Dermatology” Alopecia totalis/universalis involves more intense immune activity and inflammation than patchy alopecia areata.
In a phase 2 trial, researchers tested a topical formulation for alopecia areata and found significant hair regrowth with the treatment, but these improvements did not lead to substantial enhancements in health-related quality of life.
January 2026 in “JEADV Clinical Practice” This study examines the depiction of a soldier with an atypical hairstyle resembling alopecia in an Isenmann painting, possibly reflecting medical conditions like tinea capitis or alopecia areata to emphasize the soldier's moral degradation, though artists historically mixed medical conditions for stylistic purposes.
This study found that both intradermal BCG vaccine and intralesional triamcinolone acetonide were similarly effective for treating patchy alopecia areata, though intralesional triamcinolone was preferable due to fewer side effects associated with BCG vaccine.
