From the description of your problem, I think all you need is vitamins and minerals supplement. Vitamin H (Biotin) is a very useful oral medication. There are combos with pantothenic acid and minerals. One anti-oxidant capsule daily also helps. Correct anaemia if present. Yet another important point is that you must check your thyroid function, as this governs hair loss/growth in a big way. I sincerely feel that you will get the hair you desire if you look at the above details.
