This temporary hair dye works on the hair to add light color and usually only lasts two washes. In addition to the colors used, the texture, length and health of the hair contributes to the durability of the color. Temporary hair dye does not penetrate dandruff or discoloration causing permanent change, but it stays in the hair and begins to fade from the first shampoo.
Temporary hair coloring gives a more natural color and is easier to use. Direct dyes are made up of large colored particles that are deposited on the hair cuticle. These particles are too large to penetrate dandruff and wash it off the next time you wash your hair.
