The term “co-wash” is a contraction of the term “conditioner wash.” Conditioner washing is simply washing the hair with conditioner only, skipping shampoo altogether. Many choose to co-wash between shampoo days as a way to prevent dry hair.
Some people co-wash with commercial cream conditioners, but this can cause buildup in locked hair. Safer options for co-washing locked hair include aloe vera and coconut milk.
