Our grandma's hair spray contains sodium laureth sulfate and hydroxyethyl cellulose. It can have nice, smooth, silky color effects. Its use is simple: do a sensitivity test 24 hours before dyeing, and wash your hair before dyeing. Brush the premix to the hair strands, leave the premix on the hair for 40-60 minutes, then wash the hair thoroughly, and finally use milk (H2O2) with dioxy, using a 1:1 ratio of dioxy milk to hair color cream. And hairdressing.
