WHEN SHOULD YOU USE CONDITIONER?
The outer layer of the hair strand is called the cuticle. When your hair gets wet, the small scales on the cuticle lift, allowing the water and your shampoo to rinse the hair from within. Your conditioner ensures that the cuticle closes and tightens after you wash your hair with shampoo. It leaves your hair strong, soft and shiny. Conditioner makes your hair feel smooth. When the hair is smooth, it becomes shiny as well, because the smooth surface is better at reflecting light. Since your conditioner closes the cuticle, it must be used every time you wash your hair. First shampoo, then conditioner. If you use a hair treatment, the order is: shampoo, treatment, conditioner. If you add a nourishing oil to your hair treatment, you should wash an extra time with shampoo before you finish with conditioner.
