Our grandmother`s grey hair styling agent contains deionized water, cetyl alcohol, and cetyl ether. It can achieve beautiful, smooth, and silky color effects. Its usage is simple: conduct a sensitivity test 24 hours before dyeing, and wash your hair before dyeing. Brush the premix onto the hair strands, then leave the premix on the hair for 40-60 minutes, thoroughly wash the hair, and finally use milk (H2O2) with hydrogen peroxide in a 1:1 ratio with hair dye. And it can also be used for hairdressing.
