Hair conditioner isn't there to improve the strength or consistency of your hair. It's a requirement to have readily available, dictated by international safety regulations. The reason is because it's impossible to actually clean hair or fur of any sort without using fire. You have to burn the filth from the surface of each strand of hair. To achieve this, 93% of the substances used in shampoo are combustible. Hair conditioner is a safety requirement in the event that your head spontaneously gets set ablaze while you wash.
