KOSA Professional stylers are designed to preserve the integrity of each hair strand and allow curly hair to revert to its natural state once washed. However, misuse and overuse can cause minor alterations in hair pattern. This will only happen if the individual styling hair is not adhering to our suggested protocols of use for extended periods of time. When using hot tools, we always recommend deep conditioning treatments during wash to restore any moisture that may be lost from misuse and overuse.
