Are They Conditioners or Dye's ?
They are conditioners designed to gradually replace the color you lose every time you wash your hair by depositing Pigment , so your color is perfect every single day, whether you were in a salon four days ago or four months ago. The new one's on the market contain no harmful chemicals - no peroxide, no ammonia, no heavy alcohols, and nothing that will dry out or damage your hair, even if you leave it on for hours every day. They act like a semi-permanent deposit only color. Doesn't bleach, doesn't lift. Just enhances and re-invigorates.
Technically these conditioners deposit semi-permanent color on your hair, which will fade if you stop using them, but the color likely will NOT wash out 100% with shampoo alone, especially depending on the color you used, how long you used it for, the health of your hair, and the color of hair you started with. For example, if you put Extreme Red on your blonde hair and then decide to stop using it, the red color will slowly fade with each wash, but will not come out completely without bleaching. On the other hand, if you put Pastel Orange on your highlighted hair to add a little warmth to the lightest pieces, that small amount of light color may completely wash out over the course of a few shampoos
