One of the most important things in hair care is how much and how we wash our hair. Since hair washing is sometimes a job we do every day, it may seem simple to you but it is a very important factor. First of all, if your hair is oily, you should stop washing your hair constantly. Before you degrease your hair, the more often you wash your hair, the more often it will be oiled. If you are going to wash it with hot water, you should wash your hair twice a week at most. Hot water opens all your pores and your skin remains exposed to all dust and other dangers. You can wash your hair every two days with cold water.
