Yes, it could extend the life of the BKT. I often tell my clients, instead of shampooing every time to just rinse and condition. There is no need on long hair to shampoo everyday since it diminishes the keratin treatment faster. Some of my girls that go to the gym are now doing this instead of shampooing after working out.
