I have hair growing pills?

Yes, they might do, but probably not that much on their own. Those minerals are needed by the hair so it will probably definitely make the hair a lot stronger if it does grow. To make your hair grow, the best thing that works is to get blood flowing to the scalp - that is absolutely your best shot. You can lie upside down and/or massage your scalp, or brush it (your scalp, that is) with a natural boar bristle brush - not very comfortable but it will get the blood flowing. If you do this often, more than 30 mins a day, it will help A LOT. If you do that in conjunction with the pills, it will make your hair a lot healthier and shinier as well. It's a lot of effort but it will probably be worth it.
