Avocado is becoming more and more popular with women who have dry, frizzy and damaged hair. Avocado is rich in protein and vitamins that moisturize and nourish your tresses and scalp and promote hair growth. Rub the pulp into the scalp and tresses, leave it for about 15 minutes and wash away. Add avocado to your masks or use it as a hair conditioner each time you wash your hair. For a better effect, combine avocado pulp with egg yolk. Massage your scalp with this paste for 10 minutes and rinse as usual.
