Kenalog is the brand name for triamcinolone acetonide, a corticosteroid that helps reduce inflammation. When injected into the scalp, it calms the immune response around the hair follicles, allowing hair to begin growing again. Cool Peel CO2 laser treatment can effectively improve the appearance of wrinkles, fine lines, acne scars, uneven pigmentation, sun damage, and skin laxity. By suppressing inflammation around the affected follicles, Kenalog can halt the autoimmune attack and restart the hair growth cycle. It is most commonly used for alopecia areata and other inflammatory hair loss conditions.
