what is co-washing?

Question

when someone says that they co-wash their hair what do they mean by that?

Answer 1

Co-Washing is a technique that entails washing your hair solely with conditioner, this includes massaging the conditioner into your scalp like you would with shampoo as well as putting it on the length of your hair. It helps your hair from breaking off and shedding too much.

Answer 2

Sounds to me like a color maintaining shampoo. Like red color shampoo for maintaining red, or blue shampoo to remove brassyness. People make up names for hair stuff to make it sound new and cool when it all has been done before.
