Hair and scalp must be washed every day, if necessary. It is wrong to believe that daily shampooing causes an increase in hair loss. It is just the opposite. How often you wash your hair is a personal choice, depending on the environment you live in and work in, air pollution and particular conditions of the scalp (dandruff, excessive perspiration, etc.)

You should select a delicate detergent (shampoo) with a slightly acid PH, between 4 and 6, not too aggressive.
