Generally, people have specific habits when it comes to washing their hair. Some wash their hair every day, while others do it only two to three times a week. However, there are also those who do not have a fixed schedule for washing their hair. Washing hair too frequently can make it dry and dull, while washing it infrequently can cause problems such as dandruff and unpleasant odor on the scalp. This is often confusing, but some experts have provided advice that helps determine the appropriate frequency.

1. Hair Type, People with oily hair types need to shampoo more frequently, and vice versa for dry hair types. 2. Age, Oil production by the scalp tends to decrease with age, so shampooing does not need to be done too often. 3. Scalp Health, Conditions like dandruff, which are characterized by flaking skin, require more frequent shampooing. 4. Activity Level, the more physically active a person is, the more often they need to shampoo.

1. Hair becomes dry and dull. 2. Hair becomes curly. 3. Hair becomes fragile. 4. Scalp experiences irritation, dryness, and itchiness. 5. Hair experiences damage.
