When swimming the Kmax hair fibers will go away?

Kmax hair fibers are water resistant so they will not go away during the swim, however they will be removed when washing the hair with a shampoo. Without using a cleansing shampoo, after the swim you will probably need just a touch up but the most of the hair fibers will remain in place. Clearly it depends on the type of swim: with a short swim in the sea to cool off nothing happens, while a prolonged swim could remove some of the keratin fibers, making necessary. a touch up.
