What does the term "Co-wash" refer to?

The term "Co-wash" specifically refers to a method of cleansing hair using a conditioner in place of traditional shampoo. This practice is particularly popular among individuals with curly or textured hair, as it helps maintain moisture while effectively removing dirt and build-up from hair without the harsh effects of sulfates commonly found in shampoos.

Using a conditioner mixed with water can help to gently cleanse the scalp and strands by leveraging the cleansing agents present in the conditioner itself. This method can be beneficial for maintaining the hair's natural oils, which is crucial for those looking to keep their hair hydrated and healthy. Co-washing promotes softness and curl definition, making it a staple technique in many hair care routines for specific hair types.

The other options presented do not accurately describe what co-washing is. A shampoo for oily hair would typically have specific cleansing agents designed to strip excess oil without being overly drying. A daily detangler is used primarily to untangle hair and may not have cleansing properties. A leave-in conditioner provides moisture and can help with styling but does not serve the same purpose as co-washing, which focuses on cleansing while conditioning.
