Shiseido Professional Primience AM13 is a high-quality hair coloring product designed for professional use. This product offers vibrant and long-lasting color while caring for the health of your hair. The specially formulated dye provides excellent coverage, even on stubborn grays, and delivers a radiant shine that enhances your natural hair texture. To use Shiseido Professional Primience AM13, start by performing a patch test 48 hours before application to ensure no allergic reactions. Once ready, mix the hair color with the appropriate developer as recommended by your stylist or the product instructions. Apply the mixture evenly to dry hair, starting from the roots and working your way to the ends. Allow the color to process for the time specified in the instructions, usually about 30 to 40 minutes. Rinse thoroughly with lukewarm water until the water runs clear. Follow with a color-safe shampoo and conditioner to maintain the vibrancy and health of your hair.
