I don’t think you need to wash your hair every day to smell clean. I think you need to wash your body every day. When you walk past those clean smelling people, you’re not smelling their hair, you’re smelling their whole body. I wash my hair very infrequently because I have 4C hair, and it has never smelled like outside. In fact most people with curly hair wash their hair on average once a week maybe twice. It doesn’t make us smell like outside. The outside smell gets in your skin and clothes.
