To help get rid of dandruff quickly, use anti-dandruff shampoos containing ingredients like ketoconazole, selenium sulfide, pyrithione zinc, or coal tar, following the instructions for use. Maintain scalp hygiene by regularly washing your hair with gentle products, manage stress levels, and maintain a balanced diet to promote a healthy scalp. If dandruff persists or worsens, seek advice from a dermatologist for further evaluation and specialized treatment options.
