Homemade Hair Mask | Take a medium sized banana, an egg yolk, 1 tablespoon of honey, half avocado and 2 tablespoons of olive oil. First, mash avocado and banana for making a smooth paste. Now, add other ingredients to this mixture. Mix them properly and apply it on the hair so that the hair strands are covered from root to tip. Let it stay for 30 minutes and rinse with a good moisturizing shampoo. To obtain best results, apply this hair mask once in a week for at least a month.
