Koleston 305/4 Hair Colour

Koleston 305/4 is a permanent hair color kit designed for coloring hair at home in a specific shade. The kit typically includes the color cream, developer, and instructions needed to achieve consistent, long-lasting color coverage, including on gray hair. It suits anyone looking to refresh or change their hair color themselves rather than at a salon. As with any permanent hair dye, a strand test and patch test are recommended before full application, and instructions in the box should be followed closely for best results.
