With the conditioner, leave it on for the amount of time it says to, if it says rinse off straight away I apologize but that's not likely, conditioners need to soak for the hair to be nourished, shampoos get rinsed off straight away. Conditioners only need to be applied on the mid length and end of your hair otherwise your roots will get oily faster, in saying that, if you feel you have a dry scalp try some pre shampoo hydrating oil or treatment or a good hydrating mask to put on your scalp before, after shampoo like a conditioner or even at the end of your shower, good video tho❤️
