I have used many different hair oils, and this is the best of all so far. It smells good, makes the hair soft and shiny, and neither dries out nor clumps the hair together. A big plus is that it comes in a glass bottle.
It can be used in several ways: You can apply it generously in the evening as an oil mask to give the hair deep nourishment, and then wash the hair in the morning. You can also use it after washing your hair and blow-drying (by the way, with the oil, the hair dries faster). But if you want to blow-dry your hair with a round brush to get volume or curls, I recommend using the oil after styling, as it makes the hair smooth and the curls hold a little worse.
Finally, you can of course use the oil as a finish product after styling - it gives the hair a beautiful shine.
I used 100 ml over 7 months, so it is quite economical.
