The Wella Professional Sp Volumize Mask Hair Volume Treatment is designed to enhance hair volume and body. This intensive treatment works to lift and strengthen hair from the roots to the tips, providing a fuller appearance without weighing the hair down. Ideal for fine or limp hair, it nourishes and revitalizes, leaving hair feeling thicker, bouncier, and more manageable. For optimal results, apply generously to shampooed and towel-dried hair, leave for the recommended time, and rinse thoroughly.
