Olive oil has very interesting properties that are a huge help for solving various things. Olive oil is great for strengthening your hair. It also causes your hair to stop looking dull, by making it shiny and moisturizing it. Just add two teaspoons of oil on dry hair before showering. It is important that you wear a shower cap so that the oil acts on your hair. In fact, the steam from the bath will also help the oil to better penetrate your entire scalp. After approximately ten minutes, you should remove the cap and rinse your hair normally. You can use your regular shampoo and conditioner.
