Is olive oil really good for you?

I heard a lot about olive oil being good for your skin and hair


can someone tell me what it does and how can it be used also because its expansive are there any other products that can do the same or similarIs olive oil really good for you?
It's good because it is a good source of monounsaturated fat that is good for your heart and fat is also very important in the health of your whole body. You won't want to heat it though because of its unsaturated and can easily oxidize and turn rancid... very bad for you! So I usually use it as a salad dressing or poured over veggies. This is on the beauty section though so I think you mean for your hair or face...? It's good for dry skin and maybe you can use it in your hair idk! You can buy it pretty cheap at any grocery store.Is olive oil really good for you?
i agree with the first person on everything i just wanted to add that if you soak your nails in a bowl of olive oil for ten minutes it will work wonders it is great for nails and strenghtens them and everything
