Surfactants in dandruff shampoos are typically cationic. Cationic surfactants have positive charges and are effective in attracting to negatively charged surfaces, such as the scalp affected by dandruff. They help in cleansing the scalp and hair by reducing oil and buildup, which can contribute to dandruff. Anionic surfactants (option A), nonionic surfactants (option C), and amphoteric surfactants (option D) are not commonly used in dandruff shampoos because they may not be as effective in targeting the specific issues associated with dandruff.
