I use oils regularly in my hair to keep it healthy. The name "onion and garlic" threw me off a little, but I decided to give it a try. When first applied, the oil definitely has a somewhat strange odor. Not smelly or anything like that, but just kind of strange. I've been using it almost every day since it arrived and I've found that the smell is very momentary and does not linger at all. I think the oil works very well, it absorbs well into my hair, not leaving a residue like some other oils do...
