Following this simple routine will regrow hair that is thinning or damaged. I learned this trick while working in hair salon during college. It really works!
Give yourself a strong scalp massage every day, preferably twice a day, for about 15 minutes. Do this by taking your prong hairbrush and rubbing it all around your scalp in circular movements. Really massage it. Doing this gets the blood flowing into your follicles, which is necessary for hair growth.
Every night, brush your hair with your boar bristle hairbrush. Start at the roots and brush downward to the ends of your hair. This will pull the hair's oils to the ends, making the hair nourished and healthy. 100 strokes.
Keep this routine up and your hair will be healthy and strong, and you will see a significant regrowth of your hair in no time!
