--> Co-washing is fun until you realize your hair doesn't absorb products or the products just sit on the surface of the hair! Other times, the hair feels weighed down and no product seems to help! After co-washing for a while, the conditioners tend to leave residues on the hair! How? According to JC of thenaturalhavenbloom , h air carries a slight negative charge which is enhanced when you use a shampoo with a negative charge. Hair will adsorb the conditioner better because the positive charge in the conditioner is attracted to the negative charge on the surface of hair . Also,m ost ingredients in hair conditioner attach to the surface of hair Based on this, I believe that the ingredients in c onditioners, in the process of moisturizing, , repairing damage, smoothing cuticles will continue to pill up on the surface of the hair.
