Hair loss at normal rate but hair density still decreasing

Hi Guys,

After reading quite a few posts over the net it seems like my hair fall is normal, not too excessive. Problem is that I still feel my hair thinning on the top of my head to the extent that I feel like I'm going bald. As if hair is falling at a normal rate but new hair isn't growing fast enough to maintain the Hair density at least on the top of my head. Any one know ways of stimulating new hair to grow ? Thank you.
