Hair just looks blonde, not silver?

This is effectively, the same issue outlined above. When a result looks blonde rather than silver, it is indicating warmth was present in the hair prior to application. Therefore, Chrome has been unable to display as a cool tone, but instead had to function as a neutraliser to counteract those warm tones in the hair and can now only display as a blonde hue. To remedy this issue, use Iced Platinum on top of this newly applied Chrome shade. With this method, the Iced Platinum will attempt to neutralise the (underlying) warmth, and the Chrome pigment will then pop out and display as silver.
