1. The key to the selection of anti-dandruff shampoo is that its active ingredients can control the balance of scalp colonies. 2. To choose a product that is mild in nature and suitable for your scalp, you need to use it for a period of time. 3. Use warm water every time you shampoo, make foam in your hands and then apply it to the hair, gently massage the scalp with your fingertips, and rinse the shampoo thoroughly.
4. Do not shampoo every day, 2-3 days is the best.
