This color treatment from Rohto Mentholatum's 50 Megumi line is designed to effectively dye gray hair while simultaneously caring for your hair and scalp. With each application, it not only colors white hair but also works to repair damaged strands, leaving your hair beautifully glossy and healthy-looking. It offers versatile usage, being applicable to dry hair either before shampooing or after shampooing in the shower. For optimal results, applying to dry hair before shampooing is recommended for better color adhesion. One bottle typically provides around 5 applications for short hair. For a more vibrant color, it is advised to leave the treatment on for 5-10 minutes. If you have shoulder-length hair, tying it up is suggested to prevent color transfer to your body. Afterward, rinse thoroughly with water until the rinse water runs clear. The product is available in Black, Dark Brown, and Light Brown shades. Pack size is 150g.
