[Objectives] To optimize the pet dog dyeing process of plant hair dye. [ Methods] Three factors affecting dyeing were selected including pH, concentration of dye and dyeing time. The L9(3³) orthogonal design was used to evaluate the hair colorng effect and the absorbance of cleaning solution after hair was dyed. [Results] The optimum pet dog dyeing process of plant hair dye was dye concentration of 50 mg/mL, dye pH of 7.5 and dyeing time of 1 h. [Conclusions] The coloring and fixing effects of the dye and dyeing process are good, which can lay a foundation for the development and utilization of plant dyes. [ABSTRACT FROM AUTHOR]
