Leave-in conditioners usually come in spray or cream form, and they can be used on all hair types.

These ingredients help to hydrate the hair and protect it from damage. Leave-in conditioners can be used daily, or as needed. They can be applied to wet or dry hair, and they can be used before or after styling products. Leave-in conditioners are an easy way to add extra moisture and protection to your hair care routine.
