Pro and Contra of Cleansing Conditioners

The main function of a shampoo is to clean the hair and the scalp. However, overcleansed frizzy hair is not cosmetically acceptable. Alternative methods of cleansing the hair have become popular among the sensitive hair population.

Co-washing is gentle to the hair but may lead to buildup due to residues under the cuticle scales. We discuss the pros and contras of the co-washing method in a medical perspective.
