First of all make sure you are not wearing your favourite blouse because olive oil can stain, and it is very hard if not impossible to remove. ( I know from personal experince :))
Pour a little bit on your palms an work through the ends of your hair, and apply it mainly in the pony tail area. Some people might say it is good for the scalp, but when I applyed it all over my scalp, because the formula is so greasy, even after shampooing my hair twice, it looked like I had the oliest hair ever the whole week!
Put your hair in a shower cap and wait how long you want to. 15 minutes would be ok, but you can leave it in overnight if really feel like your hair is very damaged.
I recommend this people with wild untamable hair, I just feel it would work beter for them, but I have fine, very straight hair and still love it! I should say the smell is quite strong and it smells like olives which is not the most pleasant smell, but it won't linger in your hair so it shouldn't be that much of a downside. I know olive oil can be used for everything, what do you like to use it for?
