The people of Egypt, ancient Greece, Rome and Asia have been using lemon in cosmetics. Today, it is still one of the main ingredients in beauty products. It is especially therapeutic for the hair because it cleans, refreshes and nurtures it, restoring volume and shine. To make a lemon shampoo, you need 5 spoons of lemon juice, 1 yolk, 2 spoons of rum and a little bit of a mild shampoo. Mix all the ingredients and wash the hair with them. This treatment is especially recommended to people with greasy hair and dandruff.
