Is olive oil applied to hair good for hair?

Personally, olive oil is very good. If it's for hair care, it's best to apply it to your hair after washing, not too much. Spread it evenly, and then wrap it with a hot towel for about 10-20 minutes. You'd better wash it, or it will be too oily. At this time, there is no need to put too much shampoo, which is neither oily nor protective.
