If you are loosing more then 100 hairs a day then you should start evaluating your options to check hair loss as otherwise if you are loosing hairs below this range then it is considered normal and you need not worry about that and start any medication.

There is no general best solution for hair loss and different conditions require different approach, medication, product or treatment. For example if your hair loss is due to a medical condition such as acute infection you need to treat that condition and in most cases hairs lost during such illness regrow back when health gets back to normal. If you are suffering from Male Pattern Baldness then the underlining cause is always DHT, an anabolic hormone primarily responsible for hair loss. So the treatment in this case would be either use natural supplements such as Saw Palmetto or otherwise FDA approved drugs such as minoxidil or finastride to control DHT and thus prevent further hair loss and even regrowth is possible in some cases.

So i would suggest if you really think you are substantial hair loss then ideally have a medical checkup done which takes not much time and ensure the reason behind your hair loss. Once that is known you would be in a much better position to analyze what vitamin, or products or treatment you need to use. Otherwise you may end up treating something which does not even exist and may even further deter your condition due the side effects some of the treatments carry.

Nexium is a great product for thinning hair. The smell isn’t so great, but using this system helps hair grow back thicker. Beauty supplement vitamins found at your local drugstore would also help hair grow back slightly faster.

you might want to talk to a doctor and make sure its not a medical problem like your thyroid or if its a sudden thing it might be stress and you just need some good old relaxation
