In the first 4 days following treatment, avoid shaving, showers, sweating, scrubbing, shampooing topicals and long-term exposure to sunlight. It’s okay to lightly dab the area with a wet cloth, but do not soak the head. After 4 days, it’s okay to shower (lightly), shave, and use fragrance-free moisturizers. After 10 days, you can resume your normal activities, but it’s still best to avoid long-term sunlight for 30 days.
