Is it better to shampoo in the morning or at night? Some people prefer to shampoo in the morning, some in the evening, and some do in both. A frequent question we get asked is, “how often should you shampoo?”.
To prevent your hair from drying out, it’s best to shampoo once every two days.

Some people may think that’s not enough, but the more often you shampoo, the more likely your hair gets damaged. Proteins and natural oils in your hair get washed away when you shampoo too often, causing your hair dye color to fade and loosens perms. That's why many manufacturers add keratin and essential oils to moisturize and prevent from damaging. You can maintain a healthy scalp and hair by washing at night so that rich nutrients in shampoos nourish your hair while sleeping. Also, be sure always to blow dry your hair thoroughly before going to bed to reduce friction between your hair and the loss of protein in your hair.
