The best way to strengthen hair follicles, promote hair growth, and reduce dry skin and dandruff is to increase the blood circulation to your scalp. You can achieve this by massaging your scalp with your fingertips for a few minutes a day. Reach from underneath you hair as if you were washing it, and move your fingers in a circular motion. Apply enough pressure to move the skin surface, and make sure to give attention to every area of the scalp. Incorporating a couple drops of essential oil such as lavender, ylang ylang, and cedarwood will further stimulate your scalp and make your massage more healthful and relaxing.
