Comparatively Speaking: Metallic vs. Natural Hair Dyes
By: Anthony J. O'Lenick, Jr., Siltech LLC
Posted: November 13, 2012
page 2 of 2Metallic dyes are vastly different from natural dyes in chemistry, source and use. These materials were based upon silver and lead salts and are generally used to gradually replace gray. These materials are primarily marketed to men and are available in a limited range of color, principally black. They are applied until the desired color is obtained.
To maximize the effectiveness of metallic dyes, daily application is required to reach the desired color and periodic application is required to maintain the color. Removal of the color can be difficult since the dye reacts with keratin sulfur.
