oVertone pigmented conditioners are all semi-permanent. They deposit semi-permanent color onto your hair, which will fade if you stop using them, but the color likely will not wash out 100% with shampoo alone. How fast the color fades depends on many factors, including the color you used, how long you used it for, the health of your hair, the color of hair you started with, what shampoo you use, and how often you heat treat it.
For example, if you consistently use Extreme Blue on your blonde hair for months and then decide to stop using it, the color will slowly fade with each wash but will likely not come out completely with shampoo alone. On the other hand, if you put Pastel Purple on your highlighted hair once, that small amount of light color may completely wash out over the course of a few shampoos. We have plenty of tips and tricks for fading color here.
