Don't wash your hair every day. Daily washing strips hair of its natural oils, and because curly hair is typically prone to dryness, daily washing can lead to drier hair that's more likely to break. Instead, wash every other day or a few times a week.  The tighter your curls, the less frequently your hair may need to be washed. If you do need to wash your hair more frequently, you can use a dry shampoo in between those washes. Don't “wash, rinse, and repeat”--that style advice may work for people with straighter hair, but it's no good for those with curly hair. When you wash your hair, only wash it once, but make sure that it's a thorough wash so that all dirt and oil is removed from your hair. If needed, you can wash your hair with conditioner (called “co-washing”) in-between washes. That way you won't be harming your hair with sulfates, which are found in most shampoos. Keep in mind that co-washing is great for retaining moisture but only mildly cleanses the hair.
