You will get shiny and smooth hair. (Make sure to wash your shiny hair well, as the egg odor and mayonnaise will not be easy to remove.) If you dislike the smell of eggs, you can try adding 2 tablespoons of honey in a jug of water. Then use water with honey as a final rinse to get shiny hair. Another effective way is to use apple cider vinegar with a cup of water. It is necessary to pour the water over wet hair and leave it on for 1 minute. Then rinse with cold water.
