DEEP CONDITIONER + PRE -POO OIL
Oils give hair essential fatty acids, which make it more flexible and soft. Also oil treatments pre shampoo protect hair from harsh detergents and too much water. Oils can't moisturize hair, because they repel water, but the softness and flexibility you get after using them contributes to the overall "moisturized" look.
Deep conditioning treatments can provide your hair with protein if it needs it, moisture and fatty acids (if your DT contains oils). Also deep conditioners smooth the cuticles, make hair more slippery and have anti-static effect, thanks to cationic conditioning ingredients and silicones (the longer you keep the DT on your hair, the more conditioning agents adhere to your hair and make it look and feel more, well, conditioned).
