PDP- PREDEEPPOO or DeepPrePoo TM DPP - when you deep condition your dry hair before you actually shampoo. Pre Deep Condition on dry hair for 1 to 24 hours before you shampoo. This makes my hair so soft and detangled that after I shampoo I don't even have to condition afterward. I seal my cuticles with an oil before twisting or bantu knotting, then air dry.
UPDATE: I only DeepPrePoo with coconut oil for an extended period of time. I no longer use a conditioner as a DeepPrePoo.
