Olive oil gives your hair a healthy glow: you can use it to reduce that unappealing frizzy look and achieve softer, well-nourished hair. Just like with your feet, apply olive oil to your hair and leave it on overnight. It might be an idea to wear a shower cap so that you don’t get oil all over your pillow! The oil will create a protective layer on the scalp, which will help protect your hair. If you have dandruff, you can add two spoonfuls of lemon juice and water to the oil: the lemon helps with the scales and, as we’ve said before, the oil moisturises the skin!
