TLDR Co-washing is gentler on hair but can cause residue buildup.
The document discussed co-washing, a method of cleansing hair with conditioner instead of shampoo. It was found to be gentle and beneficial for dry, sensitive, overprocessed, and textured hair, as it cleansed without stripping moisture and added lubrication. However, it was not effective at removing heavy buildup and required periodic use of clarifying shampoos to maintain cleanliness. The method was unsuitable for products containing nonsoluble silicones, petrolatum, or mineral oils due to potential residue buildup. Co-washing was recommended for sensitive and ethnic hair types but needed to be combined with clarifying shampoos every 15 days.
