Platinum blonde hair color is blonde, lightened hair that has had all warm, yellow tone pigments removed through hair coloring, bleaching, and toning.
The “term” platinum blonde was apparently invented by Howard Hughes in reference to Jean Harlow as a nickname.
There are two elements important to achieving a great platinum blonde hair color,
- The hair must be lightened to a level that oxidises (makes translucent) as much yellow pigment as possible.
- The hair then must be toned with a cool shade of color such as silver, ash, pearl, (blue pigments that counteract gold and look PLATINUM)
