If you use penetrating oils (coconut, olive, avocado) hot oils is a form of deep condition/ treatment. Many natural ladies use oils as an overnight pre-wash, then deep condition as a post-wash, can do same day or different days depending on your schedule.
Do you know your hair properties? Using a lot of oils may not a wise idea if you are low porosity for example. You should also consider hydrolysed protein treatments, most people use protein followed by a deep condition so same day.
