Don't worry. She's just saying that because it's something new to her. For most people clean hair=using shampoo, so if they hear talk about not using shampoo they automatically think dirty hair. I follow a modified CG routine. I only shampoo (sulfate-free) once a month and co-wash once a week, and my hair smells fine.
