SHISEIDO-A - SHISEIDO Sublimic Airy Flow Mask (U) 680g is a special treatment designed to protect fluffy, well-defined hair from humidity. It deeply penetrates repair ingredients and utilizes the heat of a hair iron to smooth out hair with frizz or waves. For usage, apply it to the entire hair after shampooing as a treatment once or twice a week. Leave it on for 3 to 5 minutes before rinsing thoroughly. After towel drying, using a hair iron will help set the repair effects, allowing you to feel the benefits even the next morning. It leaves the hair with a moist finish and imparts a natural shine.
