When swimming, do the Kmax keratin fibers detach?

Kmax keratin fibers are water resistant, so they will not go away while swimming, however they will be removed when you wash your hair with a shampoo. Without using a cleansing shampoo, you'll probably only need a touch-up after your swim, but most of the Kmax keratin fibers will stay in place. Clearly it depends on the type of swim: with a simple swim in the sea to cool off nothing happens, while a prolonged swim could remove a part of the fibers present, making a small retouching necessary.
