Your hair needs to fill up with regenerating active ingredients to regain its shine at the end of winter. There is nothing like an excellent nourishing mask with avocado and lemon to tighten hair scales. Mash the very ripe avocado, mix with half a squeezed lemon juice, and apply everything to your dry hair, avoiding the roots but emphasizing the ends. Leave on for fifteen minutes before using a special shampoo for dry hair.
