1. Comb your hair with a wide-toothed comb before cleaning.

2. Moisten your hair and ensure that the water temperature is moderate (not too cold or too hot).

3. Pour a small amount of shampoo (depending on the length of the hair) in the palm of your hand, and knead it gently to make it foam.

4. Gently rub the shampoo into the head with your fingers.

5. Wash hair thoroughly with water. If it is difficult to clean it once, repeat it.

6. Gently pat the hair dry. Do not rub, pull or twist, because wet hair is much weaker in elasticity and strength than dry hair.
