It is a dry oil so it wont leave your hair oily. I didn't attach the pump that came with mine so that I could control how much I use to avoid greasy hair. I use about a dime sized and my hair is shoulder length, it takes a while but after 2 months my hair was completely transformed. Hope this helps.
It smells fantastic! You can definitely make your hair oily if you use too much and concentrate it up towards the scalp. If you use a small amount and go from the midshaft to the ends and you should be fine. I love this stuff!
It smells very good. Also, it does not leave the hair oily. It absorbs into the hair easily. If you're worried about looking oily, start with a small amount until you find out what works for your hair.
