This is a permanent hair dye that delivers even and long-lasting color results while protecting the hair structure during the coloring process, thanks to PLEX technology. The Light Brown shade provides a natural and soft tone with vibrant shine and a healthy appearance. The 60 ml color tube is mixed with the appropriate amount of developer to form a smooth, homogeneous mixture, which is applied evenly to dry, unwashed hair. Leave on for 30 minutes, then rinse thoroughly with warm water. The included care treatment is used after coloring to lock in the color and maintain the softness and shine of the hair. The formula is designed with hair care in mind and is free of ammonia.
