Our gentle, ammonia-free Copper Toner works best on medium yellow bleached blonde hair (any type!).
It can also create a ginger hue on naturally light blondes. It's great to prep hair for fiery Super Cool Colours like Proper Copper and Tangerine Dream, or as a bronze finish all on its own.
The best way to check the colour your hair will go is with a strand test.
You must also do a skin sensitivity test before using it.
