Washing your hair every day is dry and easy to break. In the process of washing hair, hair scales will open when they meet warm water. Although the hair scales can be closed by themselves after opening, frequent shampooing will always cause certain damage to the hair scales. The frequency of shampooing still varies from person to person:

Fine and soft hair absorbs oil more easily than other hair. Oil will make hair flat and look less beautiful, so fine and soft hair should be washed more frequently. If possible, you should wash your hair every day, especially those who exercise regularly.

For coarse hair, there is nothing wrong with washing your hair once a week.

For medium-thick hair between fine hair and hard hair, it is usually enough to wash it 2-3 times a week.
