A conditioner is often the final part of the hair wash, and is applied either after shampooing or after wrapping the hair . When you apply shampoo to your hair, it opens up the outermost layer of the hair to remove grease and dirt stuck there. Therefore, it is good to use a conditioner after shampooing. The balm reseals that layer and makes the surface smooth and shiny again. A conditioner also contributes more moisture and makes the hair soft and shiny for a longer period of time.
