Our Granny Gray Hair Dye contains Sodium Laureth Sulfate and Hydroxyethylcellulose. It provides beautiful color effects that are smooth and silky. Its usage is simple: perform a sensitivity test 24 hours before dyeing, wash hair before dyeing. Brush the pre-mix onto hair strands, leave it on for 40-60 minutes, then thoroughly wash hair. Finally, use hydrogen peroxide with milk (H2O2) in a 1:1 ratio
