ULTIMATE SMOOTH is a professional hair care ritual designed to nourish and smooth dry, dull, and frizzy hair or hair prone to frizz. The ULTIMATE SMOOTH shampoo is formulated with Metal Purifier* technology to optimize protection against free radicals and encapsulate harmful metals present in water, thus maintaining color vibrancy. It is formulated with squalane and Omega-9 to deeply nourish the hair from within and create a protective barrier on the outside. Dermatologically tested, it is suitable for colored hair. Its nourishing formula transforms into a soft, light, and luxurious foam to eliminate impurities and prepare the hair for the repair process. With notes of jasmine, vanilla, bergamot, peach, and sandalwood, it is a true floral bouquet that fragrances your hair with every use. Apply the ULTIMATE SMOOTH shampoo to your wet hair and lather. Rinse and repeat if necessary. For optimal results, use this shampoo with the conditioner (daily) or the mask (weekly) and the Ultimate Smooth Miracle Oil Serum for nourished hair in 30 seconds and smoothing that lasts up to 3 days.** *Visit: for more information about our ingredients **By using the ULTIMATE SMOOTH Miracle Oil Serum without washing for 3 days vs. without treatment.
