A "Prepoo" is good to incorporate into your regimen. Prepoo's are left in the hair sometimes 15-30 minutes, sometime overnight. This is done prior to shampooing. I have attached a picture of three of the products I use to Prepoo. You can also use any cheap conditioner such as "Alberto V05". Some people also use oils such as Coconut or Olive Oil.
