Shampooing cleans your scalp and hydrates the hair follicles. Its purpose is to cleanse the scalp and remove dirt, skin particles, oils, dandruff, contaminants and environmental pollutants from your scalp and hair. There are conflicting views on how often shampooing should occur – daily, every other day, or less frequently? Do you need to rinse and repeat or just wash once? While there is no definitive right or wrong answer, it’s best to experiment with different products and frequencies to determine what works best for your hair. Some experts recommend more frequent shampooing for straight hair to achieve a sleek, glossy look, while curly hair can become too fluffy if it’s washed daily, so allowing a day or two between washes is suggested.
