How often should you wash your hair without shampoo (co-washing / water-only)?

How often you wash your hair without shampoo depends on your hair type and how quickly it becomes greasy. In general, one to three times per week is a good guideline to keep your scalp clean and your hair hydrated without weighing it down. This helps natural oils, such as jojoba oil or argan oil, keep your hair smooth and shiny.

This method, also known as co-washing, is ideal for dry or curly hair that tends to lose moisture quickly. It works by using the cleansing yet gentle properties of conditioners to remove dirt and styling products without stripping the scalp of its natural oils.

It is important to listen to your hair; if it feels heavy or lifeless, you are probably washing too often or using a product with too many nourishing ingredients. If it still feels greasy, you may need to occasionally use a mild shampoo or co-wash more frequently.
