It's great to use after washing as a hot oil treatment especially on damaged ends. It can also be used throughout the whole head of hair, from root to tip before washing. Let it sit while you bathe/shower then shampoo as usual and rinse well.
It penetrates the hair shaft , so the healthy properties are directed right into the hair instead of simple coating it. use it as a deep conditioner with a plastic shower cap, or to seal in moisture on top of your favorite moisturizer.
