Do i deep condition after ONLY shampooing or do i use a rinse out conditioner too?
That's up to you and your hair's needs. If your hair is a bit tangled after shampooing, you should probably use a rinse out conditioner for detangling and then deep condition (that's what I do). However, there are many who skip right to deep conditioning, and it has their hair flourishing. So it's up to your hair's specific needs :).
