No, human hair conditioners should not be used on dogs. Human hair conditioner is developed for the pH balance of humans, meaning it is formulated to not interfere with the acid mantle of the human skin. Human skin has higher acidity than dog skin, so their pH balance is different.
Dog shampoo and conditioner are formulated specifically for a dog’s acid mantle, which is important to help prevent bacteria, parasites and viruses from penetrating your pup’s skin. Using a human conditioner or shampoo on your dog may disrupt their acid mantle, leaving their skin dry and flaky and vulnerable to infection.
